Using reliable tools to check for plagiarism has saved my life in both my personal and professional life. These tools are very helpful if you want to avoid the bad things that can happen when you plagiarize. From my own experience, I know that being accused of plagiarism can ruin a person’s academic and professional reputation and even get them in trouble with the law. So, I’ve made it a top priority to set up a strong system to stop plagiarism.
The best plagiarism checkers go further, providing links to original and copied content and even grammar assistance and language advice. We compared the best plagiarism checkers based on several factors, from the size of the content database and third-party integrations to the type of client they are suitable for and pricing plans. We also examined the user interface, learning curve, and additional features, such as language enhancement suggestions.
Plagiarism detectors are available online from several brands and are built using custom algorithms. Writers can try some plagiarism software for free and check a sample of their work. Premium plagiarism checkers offer deeper scans, more advanced reports and plagiarism scores. These tools charge per page/word or a monthly subscription. Below, we have mentioned the best Plagiarism Checkers.
Best Plagiarism Checkers
Unicheck
Unicheck offers a high-quality service, combining cutting-edge technology with intelligent design, and it clearly works: more than 1,000 academic institutions worldwide use this application. This tool has access to more than 91 billion pages and library files. So you can be sure that it will check every available source for plagiarism. Also, don’t worry about being overwhelmed with data once the app has searched the Web: The results are displayed in a simple interface that includes sources and color codes for copies, and each article has a plagiarism score that is changed as you edit the article.
The Unicheck system’s 99.9% uptime means you can check for plagiarism when needed, and the authorized and encrypted accounts ensure a high level of security for users. The versatility and power continues in other areas. A personal dashboard is perfect for managing a large number of sources or articles, and Unicheck integrates with the Office 365, Google Docs, and Chrome so you can search for plagiarism without ever leaving those applications. Besides, it has an accessible API, so the tool can be integrated with other services.
Scribbr
Scribbr performed well for all types of student-relevant sources, such as journal articles and dissertations. Most importantly, Scribbr’s checker was most successful in detecting plagiarism in source texts that had been heavily edited to simulate accidental paraphrase plagiarism. The screenshot shows how the plagiarized parts were highlighted, while the substituted words were not.
Scribbr was also able to find complete matches. This means that the entire plagiarized part is correctly matched to one source, rather than multiple incorrect sources. Different colors are used for different sources to make it easier for users to evaluate each plagiarism problem separately.
The problem can be solved with Scribbr’s free citation generator. It generates correct citations for all uncited or incorrectly cited sources. Users can also combine the Plagiarism Checker with Scribbr’s dedicated tool, the Self-Plagiarism Checker. Scribbr does not require users to subscribe, but does charge a fee for each plagiarism checker ($19.95-$39.95 depending on word count). However, users cannot work directly with the tools or recheck documents for free.
Enago Plagiarism Checker
Enago Plagiarism Checker, powered by Turnitin, is a unique and cost-effective tool for fast, comprehensive and reliable plagiarism checking, especially for students and researchers. It helps you assess the originality of your manuscript using advanced plagiarism software. Its extensive database of more than 91 billion web pages and 82 million published articles ensures a more thorough plagiarism check than other checkers. It also provides a detailed, color-coded interactive report highlighting plagiarized content and plagiarism rate. It is one of the best user-friendly tools with one-click access to the upload button.
Enago Plagiarism Checker also offers artificial intelligence-based grammar corrections that detect grammatical errors and suggest corrections and language improvements tailored for academic writing. The artificial intelligence-based grammar checker comes as a downloadable file with tracked changes, so you can review the suggestions at your convenience and within your MS Word environment. In addition, the power editing mode improves your research papers by correcting sentence structure, word choice and topic-specific wording.
Grammarly
Grammarly is one of the most popular writing assistants in the world, and no wonder: it does a fantastic job of checking the linguistic correctness of written work, as well as readability and tone. It is also available as an app, as a plug-in for most word processors, and as a browser extension. It works with email clients, social networks, and even Slack and Discord, so you can always count on this tool.
Grammarly also has an excellent plagiarism checker. It uses academic papers from the ProQuest database and more than 16 billion web page sources to search for plagiarized text; if the app detects copied language or phrases, it displays a warning in the document.
Grammarly’s plagiarism checker is free, but we do not recommend this option: it will tell you if you have plagiarized, but it will not show you where. Instead, we recommend signing up for Grammarly’s paid levels to get grammar, spelling and punctuation tools, as well as clarity, engagement, tone and plagiarism detection. Grammarly is one of the best language tools on the web.
Viper
Viper found some plagiarism when the source text was copied directly, but struggled to find it among edited texts. The tool achieved average performance for most source types, but it struggled particularly with academic source types, such as journal articles and dissertations. This makes the tool of questionable use for students. Viper was often unable to associate the entire passage with a source. Instead, it attributed only individual sentences to a source. This made the downloadable report rather difficult to read, despite the useful use of different colors for different sources.
The tool does not sell the document if you use the paid version ($3.95-$26.30 per review, depending on the number of words). However, if you use the free version, the document is uploaded to an internal database. After 3 months, the text will be posted on an external website as an example for other students. This may cause problems if the content of the text is confidential.
Quetext
Quetext detects most plagiarism, but is unable to associate the entire source text with a single source. Instead, individual sentences are attributed to different sources, leading to many false positives. The website claims that Quetext checks web pages and academic sources, but in fact the tool does not work well with academic sources.
In its downloadable reports, Quetext distinguishes the severity of plagiarism by using orange for partial matches and red for full matches. Otherwise, the same colors are used for different sources. Although it is not possible to work directly with this tool, Quetext offers a citation wizard to assist with missing citations. Users can check out up to 2,500 words in a free trial, after which they must subscribe for $9.95 per month.
ProWritingAid
ProWritingAid’s online plagiarism detection tool helps find plagiarized content in manuscripts, novels and other literary works. It detects grammatical errors, style problems and more than 20 different language mistakes. ProWritingAid checks plagiarism directly from MS Word via an add-in. So, are you afraid of losing your credibility as a researcher due to plagiarism? Yes, aren’t you? That’s why you should resort to advanced detection methods to prevent this crime.

Plagramme
Plagramme has a range of functions beyond those found in many other anti-plagiarism tools. It not only checks billions of sources, but highlights articles at risk of plagiarism, potentially paraphrased sections, insufficient citations, and textual similarities. Combining this with a simple scoring system, you will be able to quickly see how much of each article is at risk.
This system is multilingual, so it can detect problems in several languages, and Plagramme also offers an authenticity service in which its editors manually check and correct documents. This service comes at a higher cost, but it is ideal if you have an important document that needs to be refined. At the other end of the scale, there is a free plagiarism checker, but it performs a quick check without the in-depth reports or access to the full product database.
Once you sign up for an account, you will be able to see Plagramme’s full range of services. The cost is a few dollars to skip the queue and a few more dollars to get an in-depth report, and you can purchase credits that work with any of Plagramme’s services.
Pre Post SEO
Pre Post SEO could not find most of the plagiarized sources, even for unedited passages of text. In addition, almost all matches were only partial, attributing individual sentences to one or more sources, rather than to the entire section. A different color was used for textual plagiarism and paraphrase plagiarism, but the tool’s judgment was often incorrect. In addition, the same color was used for different sources and the original formatting was removed, making the report difficult to read.
Despite a premium rate, the website still displayed many unrelated and distracting ads. The user can access a rewriting tool to fix the similarities, but the quality of this platform is questionable and does not help solve citation problems. Pre Post SEO is a free platform, but unregistered users are limited to 1,000 words per search. Users can upgrade to premium plan ($10-$45 per month).
Compilatio
Compilatio was able to find some plagiarized sources, but had difficulty when the source text had been modified. However, when he was able to identify a source, it was often correct. It was not possible to determine whether Compilatio was able to match the source to a plagiarized text because the plagiarized parts were not highlighted. Instead, the report shows only the general area that matches the source. This may limit the usefulness for users, as it is difficult to investigate and clarify any instances of plagiarism.
The report does not show the similarities found by highlighting the text, which makes it difficult to read the report and get a good overview of potential problems. Also, it is not possible to work in the tool, so similarities cannot be excluded from the report. Users can purchase packages of 20 credits (5,000 words for 3.99), 100 credits (25,000 words for 14.99) or 200 credits (50,000 words for 24.99). These credits can be used for multiple documents and are valid for 12 months after purchase.
Conclusion
Simply put, plagiarism is cheating. It refers to the act of copying a person’s content and passing it off as one’s own. Taking someone’s photo and using it without permission and/or proper credit can be considered an act of plagiarism. Taking text from a source and using it on one’s own website without proper citation is also an act of plagiarism.
