AI Detector
Paste text and see an AI-likelihood-style estimate.
This is a quick, probabilistic estimate from a language model—not a scan of Turnitin, GPTZero, or other third-party detectors. Use it to guide edits, not as evidence in academic or legal disputes.
Complete the verification above before running.

Frequently asked questions
Is this AI detector 100% accurate?
No honest detector is. This tool uses a language model to estimate patterns associated with AI-generated prose. Treat the score as a hint for editing, not proof for academic or legal decisions.
Does this scan against Turnitin, GPTZero, or Copyleaks?
No. It does not query external detector APIs or institutional databases. It is a single fast analysis meant for personal drafting workflows.
Is my text stored?
Text is sent to our server for the analysis request and is not stored for training. See our privacy policy for full details.
What should I do if my draft looks “too AI”?
Try rewriting in your own words, vary sentence length, add specific examples only you know, then run our AI Humanizer tool if you want a cleaner human tone.
How long can my input be?
Between 20 and 4,000 characters per run on the web, matching our other writing tools.
