Most AI detectors check a few hundred words and give one number. PaperCheck checks a whole thesis or project report (Word/PDF, up to 20,000 words) and marks exactly which lines read as AI-written and why. It also checks copied phrases against the arXiv papers you cite. Tested on held-out human writing so honest students aren't falsely flagged. 5 free checks a month. Works inside Claude and ChatGPT via MCP. Scores are estimates, not proof.

Hi everyone, I'm Adithyan, a CS student. Every semester my friends paste their reports into three free AI detectors and get 3%, 40% and 70%. Nobody knows which to believe. So I built PaperCheck to do one honest job: check the whole paper, show exactly which lines look AI-written and why, and check copied phrases against arXiv papers before you submit. In its first week it ran 1,000+ checks and 10M+ words, mostly from students checking final-year reports. The full engineering story (what broke, how the detector was trained, the cloud bills) is here: https://paper-check.me/engineering You get 5 free checks a month. I'd love your feedback, especially on wrong flags.
