Undetectable AI
Undetectable AI rewrites AI-generated text so it reads as human-written and is less likely to be flagged by detectors. It also sells detection tools of its own — for text, images, voice, video and deepfakes — plus a suite of writing utilities and a Chrome extension.
- Genuinely broad detection coverage across text, image, voice, video and forged documents
- The document verification tools address a real and growing problem separate from academic integrity
- A free tier lets you judge output quality before paying
- Clearing a false positive on your own writing is a legitimate need this serves
- Selling both the humanizer and the detector is an unavoidably conflicted position
- No published false positive rates or independent evaluation, unlike some competitors
- Humanizing costs precision — the rewritten prose is usually worse writing
