Read the full description
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.

Partial Document upload, sentence highlighting UI and arXiv lookups are buildable quickly. Accurate AI-writing detection with calibrated false-positive rates is the hard part and depends on data.
What it would actually take: The stack is a document parser for Word and PDF, a sentence-level classifier served behind a web app, and arXiv API matching for copied phrases. The hard part is a detector trained on large, diverse human and AI corpora with held-out evaluation and calibration, which needs ML researchers and substantial labeled data.
