Plagiarism Checker: Free Tools and Paid Checks
Free plagiarism checkers often search a smaller set of web pages, and a paid check gives you more to work with before you submit. Our checker uses PlagAware, which searches publicly available sources and links every match in your PDF report. Public sources, ~70B texts (per PlagAware) · Results in about 15 minutes · From $0.29/page.
This service offers paid full-document scans, not a free unlimited plagiarism check. Free tools vary in coverage and limits.
Public sources, ~70B texts
The draft discusses the relationship between evidence and interpretation. It then considers how research questions shape an argument.
Illustrative example, not an actual report or vendor interface. Highlights distinguish source excerpts, not severity. Similarity is not a plagiarism verdict.

What a False "Clean" Report from a Free Tool Actually Costs
Free tools can tell you your paper is clean. But when it isn't, the consequences of discovering that during your submission are far more expensive than $0.29/page.
Academic Misconduct Charge
A plagiarism violation finding triggers a formal disciplinary process at most universities. Even a first offence can result in a written warning and grade reduction that follows you throughout your academic career.
Failed Module or Degree
Repeated or serious plagiarism can result in failure of the module or the entire degree. You might have to retake a year or lose your qualification entirely. Either way, it costs far more than a professional pre-submission check.
Reputational Damage
Academic misconduct findings can appear on official transcripts and be disclosed to employers or professional licensing bodies. A professional plagiarism check before submission helps you review source matches; it does not guarantee an academic or professional outcome.

Free vs. Professional Checker | Frequently Asked Questions
Free plagiarism checkers often search a smaller set of web pages and may have word limits, so they can miss matches in a full paper. A paid check searches publicly available sources at scale (according to PlagAware, about 70 billion texts) and gives you a source-linked report. PlagAware has no access to paywalled or subscription journals, so treat any report as a pre-check.
A 20-page essay costs $5.80. A 60-page bachelor's thesis costs $17.40. A full 200-page dissertation costs $58.00. Compare that to the cost of failing a module, repeating a year, or losing your degree entirely. A scan helps you review public-source matches; it does not insure against academic misconduct charges.
According to PlagAware, it searches about 70 billion publicly available texts, including web pages and open-access publications. It has no access to paywalled or subscription journals or to non-public databases. Coverage of free tools varies, so check what each one says it searches.
Some free tools rely mostly on exact text matching, so rewording can slip through. PlagAware often catches lightly reworded passages, and each match links to its source so you can compare the two texts. Heavily rewritten passages are hard for every checker.
Your upload goes to PlagAware (our provider in Germany), isn't added to its comparison database, and PlagAware deletes its scan text after report creation. Our upload download tokens expire after 48 hours; this is not a maximum physical file-retention deadline. See our privacy policy. Some free tools store your document and make it searchable by others, so check what each one does with your text.
