Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many professional writing services use a plagiarism checker for research paper. However, students sometimes forget that they should too. But with so many options that pop up when you ask Google to “check my paper for plagiarism”, how do you choose the right one for detection? We’ve got the solution in the form of PapersOwl’s free plagiarism checker tool! Our simple tool makes it convenient to check any writing task without having to spend a dime. It works quickly and highly accurately, ensuring that you get the top grade you deserve. So, if you want to check plagiarism online before turning your task in, head over to our website and get started!

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

PapersOwl’s plagiarism detection tool gives you all the information you need to fix plagiarized content. Whether you’ve fallen victim to accidental plagiarism or have tried to make your life easier by copying some text from different sources, you’ll get an accurate percentage with our plagiarism checker online. If you’re wondering how to check paper for plagiarism, it’s nothing complicated at all! Simply visit our site, paste your whole essay into the relevant text box or upload the text file, click on Check For Plagiarism, and you’ll get accurate plagiarism results in a matter of seconds. You’ll see the problematic parts with plagiarism detected highlighted, with links to where similar content exists. Our service with plagiarism detector will also give you the option to check my paper for plagiarism and then to hire a professional writer to fix your task quickly if you’re busy with other things!

The Fastest Plagiarism Checker Online

Gaining insight into duplicate content only works if you get your results quickly. There are so many free plagiarism software online that promise to do the job for you. However, a lot of them are clunky, slow, and inaccurate. How can you produce original work without similarity detection you can trust?

PapersOwl stands out in this regard because it will detect plagiarism in seconds. This is a plagiarism scanner that’s able to perform a Swift Check to give you a uniqueness check right there and then. It also conducts a Deep Search, going through millions of sources on the internet to check for plagiarism. A document of about 1500 words takes only about 10 seconds to get processed! You get a clear plagiarism score of how much text is plagiarized and how much is original. All the sources that your essay matches are listed based on how much similarity there is in your academic writing. And on top of that, you get a handy Make It Unique button that’ll take you to an order page where you can ask our expert writers to rewrite your work and make it 100% unique.

All of this is done almost instantly, allowing students to continue working on their assignments without missing a beat. Not every plagiarism detection software works this quickly, making ours the best one you’ll ever use.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly. Turning such a paper in can cause multiple problems, as your professor might think you haven’t done the work at all.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose. A simple, free plagiarism check could help you check plagiarism, fix any mistakes you see, and submit high-quality text that no one will question.

Our plagiarism detector has a lot going for it. It makes plagiarism detection easier than ever before. Unlike copying and pasting each passage individually into Google, simply upload the whole file into our plagiarism checker free for students, and you don’t have to do anything else. All the matches are highlighted so you know what to change.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required. So, using our copyright checker online free to check your writing is essential. This way, you’ll submit the task only when you’re sure it meets the level of uniqueness required by your school. As a result, your grades will drastically improve when you check for plagiarism.

Student running a plagiarism check

You don't need a plagiarism checker, right?

You would never copy-and-paste someone else’s work, you’re great at paraphrasing, and you always keep a tidy list of your sources handy.

But what about accidental plagiarism ? It’s more common than you think! Maybe you paraphrased a little too closely, or forgot that last citation or set of quotation marks.

Even if you did it by accident, plagiarism is still a serious offense. You may fail your course, or be placed on academic probation. The risks just aren’t worth it.

Frequently asked questions

Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2022.

The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.

Scribbr’s  Plagiarism Checker is powered by elements of Turnitin’s Similarity Checker , namely the plagiarism detection software and the Internet Archive and Premium Scholarly Publications content databases .

The add-on AI detector is powered by Scribbr’s proprietary software.

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

  • 99.3 billion current and historical webpages
  • 8 million publications from more than 1,700 publishers such as Springer, IEEE , Elsevier, Wiley-Blackwell, and Taylor & Francis

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker. Plagiarism checks can be bought separately — prices depend on the size of your document.

Your writing stays private. Your submissions to Scribbr are not published in any public database, so no other plagiarism checker (including those used by universities) will see them.

The free report tells you if your text contains potential plagiarism and other writing issues. The premium report gives you the resources you need to review issues in detail and resolve them.

Generating your (free or premium) plagiarism report takes between 1 and 10 minutes, depending on the document size.

In that time, your document is compared to the world’s largest content database, with over 99 billion webpages and 8 million publications.

Scribbr’s plagiarism checker offers complete support for 20 languages, including English, Spanish, German, Arabic, and Dutch.

The add-on AI Detector and AI Proofreader are only available in English.

The complete list of supported languages:

If your university uses Turnitin, the result will be very similar to what you see at Scribbr.

The only possible difference is that your university may compare your submission to a private database containing previously submitted student papers. Scribbr does not have access to these private databases (and neither do other plagiarism checkers).

Luckily, many papers, theses, and dissertations are also published in public databases that Scribbr does have access to.

How you can avoid plagiarizing

ILLUSTRATION

Know the different types of plagiarism

There are several types of plagiarism, and it’s essential to understand the differences to avoid making these mistakes and prevent plagiarism in the classroom.

  • Direct plagiarism: Using someone else’s exact words and using them as your own with no credit to the source. Eliminating portions of the text still qualifies as direct plagiarism.
  • Patchwork plagiarism: Creating new text by combining exact phrases or sentences from multiple sources without acknowledging the original authors or sources.
  • Self-plagiarism: Attempting to reuse or recycle your previous work and claiming it as a new piece of work without mentioning the source of original publication.
  • Source-based plagiarism: Producing false sources within your writing or omitting one or more references from citations.

Cite your sources

Students often think of citations as a simple means of acknowledging another author's work. While this is their main purpose, there are other benefits as well.

Source citations also show readers where to go to learn more. By providing context around the citation in student papers, such as the source medium and when it was published, readers can locate the information more easily. Giving too little source information or improperly formatting it can result in unintentional plagiarism. These mistakes also make it difficult for readers to locate the original source and verify information.

Quetext's citation generator makes it easy for students to accurately cite their sources without slowing down their writing process. Once a user inputs the text, the software identifies the passages that require a citation and subsequently generates it in the style required — APA, MLA, or Chicago.

Always use a plagiarism checker

The best way to avoid severe plagiarism consequences is to use a plagiarism checker. Often, plagiarism is unintentional and results from poor paraphrasing of material found online. Using a plagiarism checker, the student can avoid accusations of any kind of plagiarism and benefit from a close review of the original material.

Quetext's plagiarism checker provides a speedy, easy process for students to receive accurate results, identifying areas of concern and providing on-page solutions.

Plagiarism Checker for Students FAQ

What are the consequences if a student is caught plagiarizing.

The consequences of plagiarism vary according to the student’s academic institution and grade level. For example, a middle school student who plagiarizes within an essay may receive a stern warning and additional instruction related to the process of citing sources or summarizing one’s thoughts.

However, students in higher education institutions guilty of plagiarism in academic papers face much steeper repercussions, including, but not limited, to failing grades and disciplinary or legal action. Factors such as the assignment itself, the instructor, and whether or not it is your first offense impact the outcome.

Depending on the severity of the situation, plagiarism can also impact a student’s reputation or future career opportunities.

How does a plagiarism checker help students?

A plagiarism checker helps students be proactive in finding instances of plagiarism before an assignment is completed and turned in with no way to correct the errors.

In addition, by identifying the potential conflicts early, students can conduct further research to find alternative sources to understand the material better and revise or rewrite the offending passages.

Plagiarism checkers also help students learn innovative writing techniques, improve their writing skills through better research and experience in summarizing ideas, and preserve academic integrity.

Do teachers use plagiarism checkers?

Many teachers use plagiarism checkers to ensure a student’s submission is 100% original work. With the rise of easy-to-use tools like Quetext, checking for authenticity and text matches is a quick and affordable process to scan millions of online data sources.

Using plagiarism checkers also allows teachers to educate their students on the importance of citing sources and the ethical responsibilities of research and opinion writing.

Plagiarism has always been a source of concern for teachers, but until now, options for manual detection have limited their opportunities to identify the problem efficiently. However, the evolution of technology in this area has made the tools more accessible than ever.

How do teachers check a paper for plagiarism?

Teachers are skilled at detecting plagiarism, especially those who have been teaching for a significant period or who teach in the areas of English or Literature. Some teachers use a simple technique of entering a sentence into a search engine to find instances of duplicate text on web pages.

However, this manner of plagiarism detection is manually intensive and dependent upon unreliable algorithms. Some may use their writer’s intuition by identifying anomalies in sentence structure, inconsistencies in vocabulary or grammar, or a combination of all of these.

Others use more sophisticated and robust plagiarism detection software, like Quetext. Quetext can scour millions of sites using DeepSearch™ technology to identify plagiarism in seconds. These tools also enable instructors to work with students to improve their writing and avoid repeating the same mistakes in the future.

Can students get in trouble for accidental plagiarism?

Yes, students can be penalized for plagiarism, even if it was an accident. Unfortunately, instructors have no way of knowing the intent behind plagiarism. Depending on the type of plagiarism, instructors may allow leeway for students to learn from their mistakes and correct the work without the threat of severe consequences.

However, repeat offenders are less likely to receive this flexibility and may face steeper penalties. Additionally, instructors of college-level courses with clear plagiarism guidelines and policies may be less inclined to let students off the hook and instead enforce severe consequences.

Is there a free plagiarism checker for students?

Yes! Quetext offers both a free and a paid subscription for students to seamlessly verify their writing. Quetext goes beyond traditional plagiarism checkers to provide students with advanced technology that puts content through three layers of evaluation in just a matter of seconds. This level of insight enables students to understand the degree to which the text has been plagiarized and decide whether to rewrite the text or use the citation assistant to cite sources.

Quetext also offers a detailed report students can use to document their editing efforts and present as proof of a plagiarism-free, 100% original content document.

Quetext's plagiarism tool also offers flexible pricing for its Pro features which facilitates the citation of online sources, attributions, and real-time feedback for writing improvement.

How can a student check for plagiarism?

Anyone can enter the text from a research paper into a search engine and find potential matches that identify instances of plagiarized content or duplicate content. However, this method is largely ineffective and does not identify every area of concern.

Students can use Quetext's free online plagiarism checker by creating an account, copying and pasting the text in question into the plagiarism checker, and receiving a comprehensive analysis with color-coded feedback, a plagiarism percentage score, and options for editing the text.

Quetext is one of the best plagiarism checkers available with high-quality insights and accurate results.

When you’re writing a paper the last thing you want is for your message to get lost due to incorrect punctuation or confusing sentence structure. You know that the great ideas in your head would make for a standout paper, if only you could get them written clearly on the page. If this struggle sounds familiar, you’re not alone.

Great ideas may be an essential part of high-quality writing, but they’re not the only component. Excellent papers and essays clearly express strong ideas with good grammar, proper punctuation, spot-on spelling, and thorough, careful citations. While this may sound like a lot, your teachers and professors are grading you on your skills as both a writer and a researcher, which means your assignments will require an ethical and attentive approach. Luckily, there is no shortage of available tools to help you along your way.

You could use a plagiarism checker free, though, these tools often lack grammatical support. Given the high stakes and rigorous requirements, the aid of a plagiarism checker without the needed support of a grammar checker could mean the difference between an “A” paper and a “C” or even “D” paper.

Thankfully, the EasyBib Plus plagiarism tool provides all-in-one support to cover all your bases. Our premium essay checker is convenient, easy to use, and includes access to a grammar and spell checker, plus a plagiarism checker. With a single scan, you’ll receive personalized feedback to help identify potentially missing citations and help improve your sentence structure, punctuation, grammar, and more.

Not sure if that noun is spelled correctly, or if the preposition at the end of your sentence is grammatically correct? The EasyBib Plus plagiarism tool is your one-stop shop to help check plagiarism, get grammatical suggestions, correct spelling and punctuation errors, and help create polished papers you can be proud to turn in. And, we haven’t told you the best part yet: you can try our tool free and scan your work for grammar suggestions right now!

A Grammar Check for Peace of Mind

You know that grammar plays a significant role in your assignments. Not only does it factor into your overall grade, but without clear and precise language, your ideas can lose their impact or might even be misunderstood entirely. Still, with so many different parts of speech and rules to learn and apply, it’s not uncommon to get them mixed up and find yourself questioning your knowledge now and again:

Can you use an adverb to modify a noun? (No. You need an adjective for that.)

Well, can you use it to modify a pronoun ? (Still no.)

What do they modify, then? (Almost everything else. Fun, right?)

Ugh. (That was an interjection .)

Does this have to be so difficult? (Nope!)

Scanning your paper with the EasyBib Plus writing tool delivers more than the basic punctuation and spell check functions that come standard in word processing programs. You’ll receive immediate, targeted feedback that can help improve the sentence structure and style of your writing. Not only can this help ensure that you don’t lose points off your grade for grammatical errors such as mismatched verb tense, but it can also help to clarify your meaning and strengthen your arguments by eliminating confusing punctuation and run-on sentences that confuse readers.

Reviewing your work to correct errors and refine the flow of your writing is a critical part of the revision process for novices and novelists alike. Even the most conscientious of wordsmiths might make mistakes, such as using a conjunctive adverb in place of a coordinating conjunction or pairing a plural determiner with an uncountable word. They likely appreciate a subscription-based or free grammar check as much as a beginning writer. That’s why the EasyBib Plus writing tool is designed for all writers, from students who are still learning the fundamentals to published professionals who get paid by the word.

The EasyBib Plus writing tool provides quick, targeted feedback that you can use to help improve your writing immediately. Also, our free resource library is available 24/7, just like the rest of our tools, to help you brush up on the areas that challenge you the most (Conjunctive what? Uncountable who?) That means you can continue to sharpen your skills and improve your writing over time, which will help make finishing your next project easier.

Why is Grammar So Important, Anyway?

Why is grammar important? As long as others know what you mean, does it really matter if you use proper grammar? These are age-old questions, but the answers remain unchanged. Grammar is important for many reasons:

Communication:  Communication is about more than merely listening and talking. We communicate in myriad ways: with our voices, our mannerisms, our facial expressions, our actions, and frequently, our written words. Written communication is just as important as all the other ways we broadcast our thoughts and feelings. Unlike our other communication methods, though, written communication leaves a record. While most of us relax our style when talking to or texting friends, the fact remains that more formal venues require a more formal tone. Proper spelling, grammar, and punctuation are a necessary element of professional and academic writing, so running your work through a spelling and grammar check before you submit it is an absolute must.

Clarity:  Expressing your thoughts, ideas, and opinions is an uphill battle when you communicate them with less-than-stellar punctuation, spelling, and grammar. A missing or misplaced comma, for example, can entirely change your meaning:

  • Call me Ishmael = My name is Ishmael.
  • Call me, Ishmael = I want Ishmael to call me.

Spelling errors can result in similarly muddled meaning:

  • Her shoes perfectly complemented her dress. = Her shoes and dress go well together.
  • Her shoes perfectly complimented her dress. = Her shoes can both speak and engage in flattery.

Grammar deficiencies such as a dangling modifier yield similarly confusing results:

  • I saw the girl’s purple backpack in the library. = The purple backpack belonging to the girl is in the library; I saw it.
  • I saw the purple girl’s backpack in the library. = You know the girl who mysteriously turned purple? I saw her backpack in the library. This week has not been easy on her.

Credibility: Establishing your credibility is critical whether you’re writing for school or business. Proving that you can reliably communicate using proper grammar is essential to establishing and maintaining the trust of your teachers, professors, readers, customers, and colleagues.

What Happens After I Upload My Paper?

Once you upload a paper, the EasyBib Plus grammar checker scans your text and highlights grammar issues within your document so you can see it in context. For users running a grammar check and spell check using the grammar check free tool, up to the first 5 issues are shown. For subscription subscribers, all of the areas that require your review will be highlighted once the scan is complete.

No matter which version of the tool you’re using, your feedback will include detailed explanations so you can understand why the text was flagged. Other highlighted areas will include examples of how the issues can be fixed. Some will include a detailed explanation as to why the issue was flagged. This personalized feedback allows you to make an educated decision about whether to edit your text or dismiss the suggestion, so you’re always in control of your final draft.

Subscription users also have the plagiarism checker at their disposal when scanning their papers for style and grammar suggestions. Just as with our other writing tools, when you use the tool to check plagiarism, changes are never made without your review, so you are always in the driver’s seat. You can review each highlighted area as well as the sources of matching text and will always be given a choice to either accept or ignore both citation and grammar suggestions.

Whether you are a student or a professional, the EasyBib Plus tools are powerful allies that can help you improve your paper, establish credibility as a writer, and maintain an ethical writing process.

Check for Unintentional Plagiarism

Persistent use of the best grammar checker and spell checker you can find will help to shape up the style and substance of your composition. However, to ensure the integrity of your work and root out unintentional instances of academic dishonesty, you’ll also need to incorporate a subscription-based or free plagiarism checker for students.

The ability to scan your paper and check plagiarism and grammar before submitting your work is an invaluable tool for students. It’s so valuable, in fact, that students are not the only ones who consistently use this type of software.

Many teachers and professors use a service to ensure that student papers are original and include properly formatted and sourced citations for all reference materials. For some, this may be a consistent element of their grading process, while others may utilize one only when they feel there is a reason to do so.

What Exactly Does a Plagiarism Checker Do?

If you’ve used an online plagiarism checker before, you may be familiar with the process that these tools employ. For those who have never used one, it can be helpful to understand how these tools work and what you should expect as a result of using one.

The most basic free tools will scan your paper and provide you with a percentage that indicates how much of your work is original. This feature can be useful to a point, as some instructors and institutions set a percentage for the amount of similar text that is considered acceptable. This policy does not mean that they are lenient about academic dishonesty but, instead, that they recognize that similar or even matching word choice is not always an indicator of copying.

However, some schools do not tolerate any form of incremental plagiarism, period. In these institutions, “check paper for plagiarism” is likely a standard action when grading all papers.

With a free plagiarism checker, the percentage of word-for-word plagiarism in your text may be the only feedback you receive. Moreover, some of these providers may wade in unethical waters, and offer essay writing services in conjunction with their checking services. This is why many students and teachers prefer subscription-based checkers that focus on integrity, such as the EasyBib writing tools.

With our premium tools, you get more than just supporting proof that your paper is original and in your own words. Your writing is scanned for potentially matching text and areas that needs your attention is highlighted. We’ll provide you with the source of the matching text so you can review it and decide how to proceed. If you agree that a citation is needed, our citation tools and resources will provide you with the information you need to help format and insert the new sources in your text as well as your works cited page.

How Does the EasyBib Plus Online Plagiarism Checker Work?

The EasyBib Plus writing tool provides an all-in-one spell check, grammar review, and plagiarism checker that not only helps you with the paper you’re writing now but enables you to gain new knowledge and improve your writing for the future, too.

Our essay checker searches online for phrases, sentences, or passages that are similar to those in your paper. If it returns matching text, this may indicate that you have passages that are missing citations.

Just as with many checkers, our tool will tell you how many instances of matching text it finds in your paper. Our plagiarism tool is designed to do more than most free tools, however.

When a portion of your paper is flagged for review, we provide you with the source that it matches. As with our online spell check tool, you have the power to review each area and choose how to proceed. If you decide to cite the flagged text, you can review the suggested source and access our citation tools to help create a proper citation and start building a bibliography for your paper. Or, you may determine that no citation is needed, in which case it’s simple to dismiss the suggestion and continue to the next section.

If you’re unsure about how to proceed, our library of resources can help you learn more and make an educated decision. In this way, you gain more than just the ability to correct your work; over time, you can learn how to avoid plagiarism altogether.

Reasons Your Teacher May Run Your Paper Through a Plagiarism Detector

As stated previously, your teachers and professors grade papers with a fixed process that includes “check paper for plagiarism” as a standard, across-the-board action. Others may check for plagiarism only when they feel there is cause to do so. There are a few red flags that may stand out to them while reviewing a paper that would lead to their running a plagiarism check, including:

Style/Voice:  Most teachers are familiar with the style and voice that you use in your writing. While most will hope that the feedback they provide when grading your work will help you to improve problem areas over time, a paper or essay that has a dramatically different style or voice than the work you’ve previously submitted can be a red flag.

Inconsistency:  Changes in the font, font size, formality, formatting, and more may indicate that portions of a paper have been copied and pasted. If these inconsistent passages are not presented as quotations or don’t include citations, this may further indicate to your teacher that there’s plagiarism in the paper.

Old References:  Part of a well-researched paper is verifying the legitimacy and relevance of your sources. While some older references may be acceptable depending on the topic, if all of your sources are outdated, it may lead your teacher to believe that you’ve recycled your own work or someone else’s.

What is Plagiarism?

If you’re looking for a free online plagiarism checker , you’re already aware that it’s not something you want to be found in your papers. However, you may still be wondering: what does plagiarism mean? It’s a reasonable question and one that merits exploring. After all, some of the actions and circumstances that fall within the plagiarism definition come as a surprise to those who only learn that they’ve committed them after it’s too late.

So what is plagiarism? To define plagiarism in the most basic sense, you might say that it is taking someone else’s ideas and words and passing them off as your own.

If your goal is avoiding plagiarism entirely, you’ll need to go beyond the basics to thoroughly define plagiarism, recognize it, and keep clear of it. Some examples of plagiarism that students find surprising include forgotten citations, poor paraphrasing, and re-submitting your own work in whole or in part for more than one assignment. This useful article provides more help in recognizing and understanding the different forms that academic dishonesty can take.

Of course, using your own words and ideas does not count as plagiarism, nor does using common knowledge . Basically, common knowledge is information that is well known by the average person. Examples of common knowledge:

  • there are 12 months in a year
  • the freezing point of Celsius is zero degrees
  • Socrates was a Greek philosopher

So should you only include your original thoughts and common knowledge in your papers? Of course not! Research-based assignments are meant to demonstrate your skills as a researcher, after all, as well as your ability to build upon the work of others to formulate new ideas. To avoid accidentally committing an act that falls within the plagiarism definition when you’re using another person’s words or ideas, though, you need to give them proper credit. This means you’ll need to clearly identify direct quotations or properly paraphrase them when including them in your paper.

Regardless of your approach, you’ll also need to cite your sources according to the style your professor specifies. Generally, you will use MLA format for the arts and humanities and APA format for the sciences, but it’s always best to check with your instructor when you’re unsure.

If you know what style to use but still aren’t sure how to create your citations, don’t fret! Our library of resources includes free guides to help you learn about various styles so you can properly structure and place them. And our premium tools not only help you check grammar, spelling, and originality in your papers, but subscribers also enjoy access to our citation creation tools!

What are the Different Types of Plagiarism?

In addition to the question “what is plagiarism,” you may also be wondering, “why do students plagiarize?” While some students do intentionally plagiarize because they believe they can pass off someone else’s work as their own to avoid spending time on their assignments, many others do so accidentally. They may not understand how broad the plagiarism definition is or they haven’t learned how to research and cite their sources properly. That is why it is vital to recognize plagiarism in all of its forms if you wish to ensure the integrity of your work.

Examples of plagiarism & How to prevent it

Direct plagiarism:

Intentionally copying another person’s work without including a citation that gives credit to the source. When most students are asked to identify potential plagiarism examples and behaviors, this direct and deliberate act is what they think of first.

  • Prevention: If you use an idea or quote from another source, cite it in the text. Make it clear that it was not your own words. 

Incremental plagiarism:

Copying parts of another person’s work, such as phrases, sentences, or paragraphs without crediting the source. When deciding which tools to use to check a paper for plagiarism , instructors often seek out those that will identify incremental forms as well as instances of direct copying and similar phrasing.

  • Prevention : Decide to either directly quote the phrases or sentences you want to use, or write a good paraphrase. In both cases, be sure to add a citation. Using a plagiarism checker could also help you identify problematic passages.

Self-plagiarism:

Academic self-plagiarism occurs when a student submits the same paper or parts of a paper for more than one assignment. When your instructors are grading your papers, they’re assessing your research and writing skills in the present. When you submit work that you completed in the past, they are both unable to evaluate your current skills and unaware that you haven’t completed the assignment.

  • Prevention: Write a new paper for each assignment you’re assigned. If you feel strongly that your past work could enhance your new paper, speak to your instructor and ask for permission first.

Misleading citations:

Including a citation for a quote or idea that misrepresents the source material. This can occur if a student does not understand the reference they are citing; if a student includes a citation for a disreputable source; or the source material simply does not align with the idea or argument that the student has attributed to it.

  • Prevention: Carefully review your assignment to understand it. As you research, take the time to evaluate each source notes . Remember, it’s better to have quality citations over an abundance of citations.

Invented sources:

If a reference in a student’s bibliography is found not to exist, it is considered an invented source. This may occur if a student couldn’t find a reputable source to back their argument, or if they needed to include additional references to meet the requirements of the assignment and chose to take an unethical shortcut rather than completing the required amount of research. No matter the reason, this behavior ultimately hurts them in the long run. Not only will they fail to gain the experience they need to conduct research in the future properly, but they’ll also experience significant consequences if they’re caught.

  • Prevention: Set aside time to do proper research so you can find enough sources. Start creating a list of sources as you’re researching and take good notes. This will help you keep track of your sources so none are forgotten. If you do end up forgetting where a quote came from, a paper checker could help you pinpoint the original source. 

Patchwriting/Spinning:

Patchwriting is often confused with paraphrasing, but there’s a significant difference. When you paraphrase, you demonstrate that you understand the topic well enough to restate it in your own words. When you patchwrite or spin, it is more akin to a word-swapping game; there’s no need to understand the subject, merely to have access to a thesaurus so you can substitute enough synonyms to mask the source material. This can be intentional, but it may also be a result of having a poor understanding of how to paraphrase.

  • Prevention: Using your own words, write down the key points of the phrase or idea, and put them together in a sentence. Be sure to include a citation as well. 

A good way to test if you’re patchwriting or paraphrasing is to remove your sources from view. If you can write about what you’ve read without looking at the source material, you likely understand it well enough to paraphrase it. If you have to review the source material with each new sentence or consult a thesaurus while writing about it (except when you’re adding direct quotations), you may be spinning your sources instead of paraphrasing them.

Academic Integrity Policies and Statements

If you’re still uncertain about what counts as plagiarism, look for your school’s/ organization’s policies on academic integrity and plagiarism. The policies of academic institutions usually cover what is considered plagiarism, the consequences of committing it, and how to avoid it. One great example is Purdue University’s Academic Integrity statement .

What are the Consequences of Plagiarism?

No matter the setting, plagiarism is not taken lightly, and the consequences can be significant. For a good reason, too! Whether in an academic or professional setting, the plagiarism consequences reflect the seriousness of the act, which is ultimately a form of theft that hurts everyone involved.

Just as with the theft of a tangible object, there can be legal punishments for plagiarism. It is, after all, a form of copyright infringement in many instances. A quick search for plagiarism articles will reveal that professional instances of intellectual theft have resulted in civil lawsuits and can even be criminally prosecuted under rare circumstances. In addition to the possible legal consequences, professionals may lose their jobs or have to start over in a new field after their acts of fraud are uncovered.

As a student, you’re likely to wonder what happens if you plagiarize in college or high school. While there will almost always be consequences for this behavior, there is no one-size-fits-all plagiarism sentence. Depending on the circumstances, academic dishonesty could result in outcomes such as:

  • You might get a zero for the assignment in which the infringement occurred.
  • You may receive a failing grade for the class. If it is a required course, this could leave you without enough credits to move on to the next level until you can repeat it and, in some instances, postpone graduation.
  • You may be expelled from your school or university.

The academic dishonesty may be noted on your transcript, which can lead to you not getting into your preferred college, graduate school, or Ph.D. program in the future.

Nobody wants to be known as a fraud or to have a reputation for dishonesty follow them through their career. And, given the consequences that can extend beyond just their reputation, it’s no wonder that professional and academic writers who wish to avoid them take the time to understand the complete definition of plagiarism and run their work through a plagiarism checker before sending it out into the world.

Even the vigilant can fall prey to inferior tools, unfortunately. Before selecting a plagiarism checker, you should understand how they work and what they can (and cannot) detect.

How We Check for Plagiarism

When exploring how to check for plagiarism, most students and professionals conclude that including a checking tool in their revision process is not only helpful but necessary. When you consider the Herculean task of checking each line of your paper against the text of each of your resources, the benefits of a checker are clear. Moreover, this manual approach would only alert you to matching text in the sources you’re aware of, after all, and leaves the sources you haven’t reviewed untouched.

But, hang on. Why would sources you haven’t reviewed factor into your review? The answer to this lies in the plagiarism definition you learned above. What is plagiarism? It’s presenting someone else’s work or ideas as your own, intentionally or otherwise. It is not uncommon to uncover an idea while you’re researching a topic and later misremember it as your own. This might even occur years after you originally came across it.

You might wonder: how can plagiarism be avoided if you have to account for the source of every thought you include in your work? A few exceptions minimize the scope of this. Common knowledge about your topic does not need to be supported by a citation, nor does knowledge that you gained through your personal experience. Using a subscription-based or free plagiarism checker will help you locate any passages that may fall into these categories so you can review them and decide for yourself whether a citation is needed.

EasyBib Plus writing tools provide easy, convenient, and reliable support to help you find potentially missed citations and can help you improve your paper into a high-quality paper with integrity. Simply upload your paper, select the checker, then sit back and relax as the site scans your document. In mere moments, we’ll search the web for passages of similar text and highlight duplicate content for your review.

Regardless of the tools you use to help you revise and polish your work, it’s ultimately your responsibility to ensure that you’re writing and submitting ethical work. That’s why our tools go beyond the basics and require your participation. The tool never automatically makes changes to your paper, but only flags sections that may need your attention and provides you with the matching source so you can to make an educated decision.

If you find that a citation is needed, our citation tools can help you create properly formatted citations and develop a complete bibliography. And, if you review the passage and determine that the match is coincidental, you can dismiss the alert and move on to the next.

Seamless Citation Creation

Professional writers and students alike can find creating citations incredibly confusing. Nevertheless, they are an integral part of a well-written and researched paper and a requirement in almost all academic settings. But, have you ever wondered why they are so important? Citations really do have a purpose—other than driving us crazy— that make it necessary always to cite our sources.

We cite our sources for a few important reasons:

We need to give credit where credit is due. When you use a quote from someone else’s work, you need to give credit for using their words and ideas. Research is often based on the works and ideas of others. However, to include the words and ideas of another without giving them proper credit is to plagiarize, even if the act was unintentional.

In addition, showing that you’ve done proper research by including in text & parenthetical citations and a comprehensive list of sources to back up your arguments gives your work a layer of credibility that can help you earn the trust of your reader or teacher.

Readers can find the sources you used.  When you’re writing high school or undergraduate papers, your only readers may be your instructors and peers. However, including citations at every level of writing helps to ensure that anyone who reads your work can access your sources to check their accuracy, learn more about your topic, and further their own research.

Sources can take your research and learning to the next level, too. When you are conducting research on a topic, checking the works cited or annotated bibliographies prepared by your sources can lead you down new avenues in your research to further develop your ideas and help you write your papers.

Correctly utilizing citations gives strength to your thoughts and opinions. Understanding the value of citations does not, unfortunately, make them any easier to create. We know how confusing it can be, but don’t throw in the towel on learning how to cite websites in MLA , create your APA citation website references, or format your works cited —this is where we come in!

While a free online plagiarism detector may tell you how much of your work is unoriginal and may even identify the passages that meet their plagiarize definition, a premium EasyBib Plus plagiarism checker account also gives you access to our powerful citation resources and generator so you can:

Scan your papers with the plagiarism tool to check for plagiarism-free work before you submit.

Review flagged passages to determine if they meet the plagiarism definition and create unlimited citations in APA format and MLA format for anything fitting the plagiarism meaning. Need more styles ?

Build a full bibliography for your paper right along with your parenthetical or in-text citations, which can save you hours of work along the way compared to manually creating and formatting them.

Plagiarism matters more than you think

You might define plagiarism as copying someone else’s work , whether by copying another student’s paper or taking passages directly from research sources and passing them off as your own work. But did you know that it’s not just about literal copying, but about making sure you credit your sources.

Think about it: would you want someone to take your hard work without crediting you? Of course not! So it’s important to make sure that you don’t accidentally use the work and research of someone else without giving them the credit they deserve and that formatting requires. A plagiarism check provides you with peace of mind that you haven’t forgotten to cite sources.

A paper check for peace of mind

Plagiarizing the works of another writer is a big deal in school and in life. Even if it’s a mistake, it’s the sort of mistake that no one wants to make because it’s a pretty serious issue. Luckily, it’s pretty easy to avoid if you have the right tools at your disposal! The first step to avoiding it is knowing what it is.

One plagiarism definition — probably the most commonly discussed one — is to directly steal somebody else’s words and pretend they are yours, or, alternately, to use someone else’s words and not give them credit. These actions are deliberate attempts to deceive, and they do happen in real life. More often, however, issues arise from not from intentional misconduct, but from innocent or careless mistakes that simply give an impression of copying because sources haven’t been credited as they should.

Most teachers ask you to cite the works of others so you learn to be an ethical researcher who does not plagiarize . In many cases, teachers will use a plagiarism tool to make sure students are following guidelines. However, with so many assignments, chores, friends, and other parts of life going on, it can be difficult to keep track of everything.

That’s why getting a plagiarism check — like the one from Citation Machine — can save you from forgetting to cite sources. It’s simple to use, catching missed citations and other errors. Finding and correcting these problems before you turn in your paper can make the difference between a stellar grade and a failing one.

Still not sure about it? Try our essay checker with Citation Machine Plus for free. Simply copy and paste or upload a paper into our tool and immediately get a grammar check!

Snag an intelligent paper check

Personalized writing suggestions at your fingertips? Yes, the dream is real, and it’s right here at your fingertips, thanks to the easy-to-use Citation Machine Plus paper checker. But that’s far from the only thing it can help you with.

Why wear out your own tired eyes after you’ve already researched, written, and proofread that long essay or term paper? Even the most attentive student might miss a minor detail or in-text citation when reviewing their own paper. Instead, use our software to check your paper and catch missed citations or accidentally copied passages of text before you turn it in. With Citation Machine Plus, a smart plagiarism check is only a few clicks away, allowing you to catch missed citations or accidentally copied text.

So why not try it out? It’s free to scan a paper and can help catch those pesky errors hiding in your text, even if it’s as simple as a quick fix of a  pronoun or a missing preposition . And with an affordable subscription plan, you can upgrade and unlock all of our powerful writing and citing tools.

How a plagiarism check helps you

We often think of citing sources to avoid plagiarizing as something that helps other people, because it’s focused on correctly crediting the work done by others and not passing it off as your own or accidentally implying that it’s your own by failing to cite sources. But using a plagiarism checker to do this actually benefits you, the student, too!

When you submit your paper to be double-checked and to make sure that you haven’t plagiarized in any way, you’re also protecting yourself. How does that work? It’s all based on the way these tools function in the first place. Most of them are built around algorithms that compare uploaded papers to a vast database of existing work. This may include research databases of published works (think papers in academic journals, books, newspapers, and other print and digital sources), as well as information found online on websites.

So when you submit to a free plagiarism checker — or a subscription-based one — you’re comparing your own writing to other writings online. Your essay is checked using algorithms. How does this help you? In short, it protects you from accidentally getting a reputation as a plagiarist. Once you’ve uploaded a paper, the checker will scan your writing to make sure that your writing is wholly your own, saving you plenty of headaches and ensuring that your original ideas are shining through clearly with support from sources, rather than borrowing too heavily from other research.

If that’s not reason enough to use a checker, then remember this: if you’re in any sort of formal writing class, whether in high school or in college, your teacher is very likely to have access to a checker through their department. “Check paper for plagiarism” is at the top of the to-do list when teachers sit down to grade papers — in fact, many have a rubric that has a section for academic honesty and proper citations.

Since your teachers are already using this kind of software, wouldn’t it be great if you could too? The great news is you can! A Citation Machine Plus subscription gives you access to a set of tools built specifically for students, allowing you to check your paper on your own, before even submitting your work for grading. The more you check on your own, the more you learn, which can help you avoid making mistakes in the future.

But that’s not all.

So, what is plagiarism?

Let’s start with the basics. You might be surprised about what really counts in the overall plagiarism definition. For instance, have you ever heard of incremental plagiarism? Also called “patchwork,”  this happens when you take bits and pieces from multiple sources, without citing, and pass it off as your own work. This is common with specific turns of phrase or ideas, but it’s also what can happen if you aren’t careful with citing all sources. A paper-checking service can help catch these issues before they get to your teacher’s desk.

When we talk about plagiarism, we’re talking about a wide variety of issues. It can mean deliberately copying from another source, whether it’s a book, an academic paper, or the work of a classmate or previous student. Using services that do work on behalf of a student, then put the student’s name on it, also falls into this category. As described above, deliberate incremental plagiarism — usually plagiarizing multiple sources and combining them to avoid detection — is also a major problem.

The above examples are probably the first answers that come to mind in response to the question “what is plagiarism?”, but there’s actually a lot more to it than that. Most of us wouldn’t intentionally plagiarize, but there are plenty of instances where you might do so without even realizing that you’ve done something wrong!

For instance, forgetting to cite a quoted source might result in the quoted passage tripping the algorithms when your teacher runs it through a paper checker. Or perhaps you’ve synthesized the information from your research, but you’ve inadvertently reused some particularly distinctive language from one of the original sources, making it appear like intentionally copied text even though it’s really not. Citation Machine Plus tools can help you avoid these accidents by proofreading your paper to catch any instances that could count against you and helping you fix the issues.

Here’s a detailed article if you’d like to learn more about avoiding plagiarism .

Why we cite

What do teachers want to see in your papers? When it comes to writing style, teachers will pretty much always understand that every student will have a different voice, but they’ll still be looking for certain elements that every paper should have — like citations. Essentially, the idea is to make sure that an essay has original ideas and arguments and cites sources where it uses existing information .

Remember the Golden Rule? Do unto others as they would do unto you? Most of us would not want others to take credit for our ideas, so we don’t intentionally steal someone else’s words. But with so much information in the world, it can easily occur by accident.

Unfortunately, it happens both intentionally and unintentionally enough that teachers often take student work and run it through a scan to make sure the content is original. That’s right, even teachers sometimes use online tools from a subscription-based or free plagiarism checker. It’s even a required step for many writing classes at any level, so make sure that your paper is prepared for these kinds of checks.

That being said, no teacher really wants to flag any student’s paper, and no student wants to be flagged. That’s one reason citations are so important and a vital part of ethical research and writing. When you cite your sources correctly, you’re giving credit to the originators of the ideas or quotes, which means that there’s no plagiarizing going on — just good old-fashioned research .

When you first start learning to cite your sources, you probably learned just one overall style guide. In college and in the real world, though, the style guide you’ll need to use will depend on what field you’re in. For instance, academia often sticks with Chicago citation style , while the arts and humanities tend to prefer MLA, and APA is favored by the social and behavioral sciences.

So you need MLA format help? We got you covered! How about APA format instead? No problem! We’re all over that, too! In fact, we have many more citation styles . Our classic citation tools are available for all your formatting needs.

Here’s the best part: using our tools could help you expand your knowledge for the future! Our citation formatting tools can help you become more familiar with the most popular style guides — which will make your life easier when you go to write more essays in the future! Curious about these benefits and how it works? Here’s a great place to

In addition to our paper checking tools, we have citation tools! Citing sources not only makes your work more professional, it is generally required for any formal papers or research projects.

Remember: when we ask “what is plagiarism?” the answer includes improperly cited sources along with intentional copying! Teachers can often use a paper-checking service through their schools, so we’ve developed similar tools for students to use.

Our classic citation tools make it easy to create a correctly-formatted citation for APA format or MLA format citation styles. ** We have taken the hassle out of citing your sources, and — trust us — you will notice the difference.

** The APA and MLA are not associated with Citation Machine, but our citation services follow their styles.

How to Check for Plagiarism: Ensuring Your Work is Original

Plagiarism is a serious issue, both in academic and professional settings. It involves using someone else’s ideas or words without properly citing them. Fortunately, there are several tools and techniques available to help you check your work for plagiarism before you submit it.

Here’s a guide to navigating plagiarism checkers and ensuring your writing is original:

Understanding Plagiarism Checkers:

  • What they do: Plagiarism checkers are software programs that scan your text against a massive database of web pages, articles, and academic journals. They identify any significant matches, highlighting potential plagiarism.
  • Peace of mind: Knowing your work is original reduces stress and avoids accusations of plagiarism.
  • Catching unintentional mistakes: Even paraphrasing without proper citation can be flagged, prompting you to double-check your references.
  • Not perfect: Plagiarism checkers are powerful, but they can’t catch everything. For instance, they may miss paraphrased content that retains the original meaning.
  • Limited databases: Free checkers might have smaller databases, potentially missing less common sources.

Using a Plagiarism Checker:

There are several free and paid plagiarism checkers available online. Here’s a general process for using them:

  • Choose a checker: Consider factors like features, database size, and cost. Free options are great for basic checks, while paid services might offer more in-depth analysis.
  • Upload your text: Most checkers allow you to copy and paste your text or upload a document file.
  • Run the scan: Initiate the plagiarism check and wait for the results.
  • Analyze the report: The report will highlight any matches. Review each flagged section carefully.

Beyond the Checker: Avoiding Plagiarism

  • Proper citation: Always cite your sources correctly, following the appropriate style guide (e.g., MLA, APA).
  • Paraphrase effectively: Don’t simply copy and change a few words. Rephrase the information in your own words, but still cite the source.
  • Focus on understanding: The goal of research is to learn and develop your own ideas. Don’t rely solely on copying others’ work.

Plagiarism is a serious offense that can hurt your academic or professional career. To avoid accusations of plagiarism, it’s important to use a plagiarism checker to ensure that your work is original.

Ensuring the originality of your content is essential, and the best plagiarism checkers mentioned above can assist you in avoiding the severe consequences associated with plagiarism.

By considering factors such as content database size, user interface, additional features, and pricing plans, you can select the most suitable plagiarism checker to meet your specific needs. Invest in these reliable tools to enhance your writing integrity and achieve peace of mind.

Many plagiarism checkers are available, so it’s important to choose the right one for your needs. In this article, we’ve compared the best plagiarism checkers of 2024 and helped you choose the one that’s right for you.

We hope this article helps you to choose the right plagiarism tool to check your thesis, research manuscript, and assignments.

Plagiarism in peer-review reports could be the ‘tip of the iceberg’

Time pressures and a lack of confidence could be prompting reviewers to plagiarize text in their reports. Credit: Thomas Reimer/Zoonar via Alamy

Mikołaj Piniewski is a researcher to whom PhD students and collaborators turn when they need to revise or refine a manuscript. The hydrologist, at the Warsaw University of Life Sciences, has a keen eye for problems in text — a skill that came in handy last year when he encountered some suspicious writing in peer-review reports of his own paper.

Last May, when Piniewski was reading the peer-review feedback that he and his co-authors had received for a manuscript they’d submitted to an environmental-science journal, alarm bells started ringing in his head. Comments by two of the three reviewers were vague and lacked substance, so Piniewski decided to run a Google search, looking at specific phrases and quotes the reviewers had used.

To his surprise, he found the comments were identical to those that were already available on the Internet, in multiple open-access review reports from publishers such as MDPI and PLOS. “I was speechless,” says Piniewski. The revelation caused him to go back to another manuscript that he had submitted a few months earlier, and dig out the peer-review reports he received for that. He found more plagiarized text. After e-mailing several collaborators, he assembled a team to dig deeper.

Meet this super-spotter of duplicated images in science papers

The team published the results of its investigation in Scientometrics in February 1 , examining dozens of cases of apparent plagiarism in peer-review reports, identifying the use of identical phrases across reports prepared for 19 journals. The team discovered exact quotes duplicated across 50 publications, saying that the findings are just “the tip of the iceberg” when it comes to misconduct in the peer-review system.

Dorothy Bishop, a former neuroscientist at the University of Oxford, UK, who has turned her attention to investigating research misconduct, was “favourably impressed” by the team’s analysis. “I felt the way they approached it was quite useful and might be a guide for other people trying to pin this stuff down,” she says.

Peer review under review

Piniewski and his colleagues conducted three analyses. First, they uploaded five peer-review reports from the two manuscripts that his laboratory had submitted to a rudimentary online plagiarism-detection tool . The reports had 44–100% similarity to previously published online content. Links were provided to the sources in which duplications were found.

The researchers drilled down further. They broke one of the suspicious peer-review reports down to fragments of one to three sentences each and searched for them on Google. In seconds, the search engine returned a number of hits: the exact phrases appeared in 22 open peer-review reports, published between 2021 and 2023.

The final analysis provided the most worrying results. They took a single quote — 43 words long and featuring multiple language errors, including incorrect capitalization — and pasted it into Google. The search revealed that the quote, or variants of it, had been used in 50 peer-review reports.

Predominantly, these reports were from journals published by MDPI, PLOS and Elsevier, and the team found that the amount of duplication increased year-on-year between 2021 and 2023. Whether this is because of an increase in the number of open-access peer-review reports during this time or an indication of a growing problem is unclear — but Piniewski thinks that it could be a little bit of both.

Why would a peer reviewer use plagiarized text in their report? The team says that some might be attempting to save time , whereas others could be motivated by a lack of confidence in their writing ability, for example, if they aren’t fluent in English.

The team notes that there are instances that might not represent misconduct. “A tolerable rephrasing of your own words from a different review? I think that’s fine,” says Piniewski. “But I imagine that most of these cases we found are actually something else.”

The source of the problem

Duplication and manipulation of peer-review reports is not a new phenomenon. “I think it’s now increasingly recognized that the manipulation of the peer-review process, which was recognized around 2010, was probably an indication of paper mills operating at that point,” says Jennifer Byrne, director of biobanking at New South Wales Health in Sydney, Australia, who also studies research integrity in scientific literature.

Paper mills — organizations that churn out fake research papers and sell authorships to turn a profit — have been known to tamper with reviews to push manuscripts through to publication, says Byrne.

The fight against fake-paper factories that churn out sham science

However, when Bishop looked at Piniewski’s case, she could not find any overt evidence of paper-mill activity. Rather, she suspects that journal editors might be involved in cases of peer-review-report duplication and suggests studying the track records of those who’ve allowed inadequate or plagiarized reports to proliferate.

Piniewski’s team is also concerned about the rise of duplications as generative artificial intelligence (AI) becomes easier to access . Although his team didn’t look for signs of AI use, its ability to quickly ingest and rephrase large swathes of text is seen as an emerging issue.

A preprint posted in March 2 showed evidence of researchers using AI chatbots to assist with peer review, identifying specific adjectives that could be hallmarks of AI-written text in peer-review reports .

Bishop isn’t as concerned as Piniewski about AI-generated reports, saying that it’s easy to distinguish between AI-generated text and legitimate reviewer commentary. “The beautiful thing about peer review,” she says, is that it is “one thing you couldn’t do a credible job with AI”.

Preventing plagiarism

Publishers seem to be taking action. Bethany Baker, a media-relations manager at PLOS, who is based in Cambridge, UK, told Nature Index that the PLOS Publication Ethics team “is investigating the concerns raised in the Scientometrics article about potential plagiarism in peer reviews”.

check my research paper for plagiarism

How big is science’s fake-paper problem?

An Elsevier representative told Nature Index that the publisher “can confirm that this matter has been brought to our attention and we are conducting an investigation”.

In a statement, the MDPI Research Integrity and Publication Ethics Team said that it has been made aware of potential misconduct by reviewers in its journals and is “actively addressing and investigating this issue”. It did not confirm whether this was related to the Scientometrics article.

One proposed solution to the problem is ensuring that all submitted reviews are checked using plagiarism-detection software. In 2022, exploratory work by Adam Day, a data scientist at Sage Publications, based in Thousand Oaks, California, identified duplicated text in peer-review reports that might be suggestive of paper-mill activity. Day offered a similar solution of using anti-plagiarism software , such as Turnitin.

Piniewski expects the problem to get worse in the coming years, but he hasn’t received any unusual peer-review reports since those that originally sparked his research. Still, he says that he’s now even more vigilant. “If something unusual occurs, I will spot it.”
