📝 AI Plagiarism Checker — Free
Submitting an assignment or thesis? Check it before your university does. Upload your PDF — AI scans for plagiarism risk signals (style jumps, uncited claims, copy-paste patterns), gives a risk score, and shows exactly how to fix every flagged passage.
Honest note: Turnitin matches text against a proprietary database of billions of sources — no free tool can replicate that. This is a writing-pattern risk assessment: the same red flags a strict examiner looks for.
