The ChatGPT Detector Teachers Actually Use

Is there a ChatGPT detector that works for schools? Yes - and it needs to do more than flag a percentage. Proofademic gives teachers and institutions a ChatGPT detector trained on academic writing, which means fewer false positives on legitimate student work and clearer evidence when AI was genuinely used.

Schools and universities need a tool they can stand behind when challenging a student submission. A sentence-level breakdown with confidence scores gives educators exactly that.

Trained on academic writing

Reduces false positives on formal student essays. Fewer wrong flags means more trustworthy results.

Sentence-by-sentence evidence

Know exactly which parts of a submission are likely ChatGPT. Defensible, specific, actionable.

Batch Scan for whole classes

Upload multiple files at once. Proofademic scans the batch and flags AI-generated content across all submissions simultaneously.
