Plagiarism Detection Tools

Plagiarism Detection Tools

Plagiarism results in serious consequences, including disciplinary action. Students can take a proactive approach, checking their work for issues before submitting it to their instructors. For their part, instructors can identify instances of plagiarism by checking student papers using one of the many websites and software programs available. Here are eight online services that check text for plagiarism:


This free site offers a convenient copy-and-paste section to check your content quickly. Users can also take advantage of the site's writing tools, 24/7 customer service and live chat features.

This tool checks submitted documents against billions of books, articles, magazines, Internet sources and academic journals to identify everything from subtle to very serious plagiarism. Monthly subscriptions start at $20 for students and $85 for educators. The website only requires a Web browser and the installation of Adobe Flash Player, which is free, to work. Users submit documents online, and a plagiarism report is sent to the user’s mailbox after the review is complete.


This free service uses an easy copy-and-paste window for your content. Grammarly gives you feedback on grammar and spelling along with plagiarism detection software. Buying a monthly membership unlocks additional features.


This free site allows users to detect plagiarism in any document or file that is copy-pasted or uploaded. Within a few seconds, the site generates a report dissecting each sentence and displaying all of the source websites from where the content was copied. The site places limits on word counts and number of times per day a user can run a search.


This comprehensive online plagiarism checker for educators scans papers against an enormous database of thousands of journals, millions of archived papers and billions of web pages. But Turnitin offers additional services that distinguish it from the competition, such as peer review, course management and online grading. Many high schools and colleges have subscriptions to Turnitin. Instructors who need to pay for their own subscription are charged $3 per student annually. Once instructors create an account, students can upload their final papers directly into Turnitin. Turnitin creates originality reports within two minutes of each submission, enabling the instructor to see which parts of the document are derivative.

This site offers standard and premium services. Standard credits are $.05 and premium credits are 25 cents, and they never expire. The standard version is designed for students and instructors who want a fast, cheap way to check text. The premium service uses SMART technology and multi-layered scanning for better accuracy. First, users upload text (doc, docx, odt or txt files) or paste it into the checking area. Then the system checks it for similarities against a private database and websites open for indexation. Within one minute, users are redirected to the results section, where any areas that have been plagiarized will appear. The plagiarized areas are hyperlinked to make it easy to check the source. Unlike most sites, Plagiarism Detect allows users to check both English and Spanish text.

Instructors can check student papers for plagiarism with Plagiarism Checker, one of the more basic plagiarism-detecting sites. The site is free, but instructors are limited to checking phrases rather than entire documents. After users type phrases (or paste from a computer file) into the search box, Plagiarism Checker will provide Google search results with a list of Web pages containing those phrases.


This plagiarism checker and citation assistant is user-friendly, quick, and free. Buying a membership allows users to upload multiple documents at once and provides access to more in-depth searches for plagiarism and sources.
