Best Free Plagiarism Checker

What happens when a university student submits a plagiarized essay? The possible consequences differ according to the institution and extent, but we can assure you that nowhere is it rewarded. Plagiarism can result in lower grades, automatically flunking the course, probation or suspension, or even outright rustication.

This explains the overwhelming popularity of plagiarism checker tools among students, but there’s a catch. The most reliable versions require a premium to access all available features, such as writing style improvement and grammar checks. But must you pay a fortune when you only need a plagiarism evaluation?

The answer is no, luckily! Thanks to several free plagiarism checkers that are 100% dependable. Don’t believe so? Verify for yourself in this fact-checked guide as we shortlist the top five of these platforms. Let’s get down to business!


Several features set Quetext apart from others, but none is as prominent as its copyrighted DeepSearch tech. This exclusive development conducts contextual analysis, conditional scoring, and fuzzy matching on texts, so the platform can always sniff out the smallest form of plagiarism. 

New users to Quetext can run a check on pieces with not more than 500 words, and registration is required to process more words. Upon becoming a member, you qualify for five free plagiarism assessments per month. What’s more?

The free Quetext bouquet offers a couple of great features that’ll help to attribute your sources, and the citation assistant is one of them. This feature allows you to manually cite your sources materials to beat the plagiarism trap. Sounds impressive?

Quetext’s plagiarism-checking ability is unrivaled due to the various features on offer. Contextual analysis evaluates the context in which phrases are used and how similarly structured are the words in their varying sources. What else? The fuzzy matching spec identifies rewritten phrases, notwithstanding the synonyms used. Lastly, the overall score of the text and all matches detected in it are highlighted.

Dupli Checker is a site-accessible tool for checking for duplicated content. Sacrificing fanciness for effectiveness, the resource works in a plain, basic interface that users can conveniently navigate even without previous experience with such scanners. This setup makes it much easier for students to understand their search outcomes.

Reports on searches are comprehensively presented. Duplicated content is highlighted in red with a link to its location. Further options are “Make It Unique” and “Start Another Search,” not to forget the reverse image search feature to locate publications from which images have been lifted.

Needless to say, the best thing about Dupli Checker is the leniency it has for free student members. You can access the platform even without registration, but joining is what gives you access to fifty free scans every day. Want more? Go premium, and you’ll check 25,000 words in one scan!
