PaperCheck
Turnitin AI checker — check your paper before submission
PaperCheck lets students run their own paper through the real Turnitin and see the official AI-writing score and similarity report — before you submit, not after. Most schools only reveal that report once it's too late to fix. Upload a draft (DOCX or PDF) and get the AI + plagiarism report back in minutes, with a plain-English breakdown of every flagged passage, so you can revise with confidence. Your file is deleted within 24 hours and never added to any repository, so checking here never affects your real submission. One-time pricing from $4.99 — no subscription. Independent service, not affiliated with Turnitin LLC.

Hey Fazier 👋 I built PaperCheck after seeing how stressful Turnitin is for students — and realising the problem isn't the tool, it's the timing. You only see your AI-writing and similarity scores after you've submitted, when there's nothing you can do about a 40% match or an AI flag on a paragraph you actually wrote yourself. PaperCheck closes that gap: you run your own draft through the real Turnitin first, get the exact report your instructor would see, plus a plain-English breakdown of what got flagged — so you can fix it while you still can. Files are deleted within 24 hours and never added to any repository, so a self-check here never touches your real submission. One-time pricing, no subscription — I didn't want to nickel-and-dime students. Would love feedback, especially from anyone who's been burned by a surprise similarity score. What would actually make a pre-submission check useful for you?
