AI detector FAQ
Is this AI generated?
The AI Detector gives review signals for AI-generated text risk, including score, confidence, and highlighted passages. Treat the result as a signal, not final proof.
Did AI write this text?
It can flag text that looks AI-written, but authorship still needs human review, context, and supporting evidence.
How do I check if something was written by AI?
Paste the text, run the check, review the score and highlighted passages, then decide which parts need closer human review.
Is an AI detector final proof?
No. An AI detector is a review signal and should not be used as the only proof of authorship or misconduct.
Is AI checker the same as AI detector?
On this page, AI checker and AI detector both mean checking text for AI-generated writing signals.
