How it works
Paste the text
Drop in any passage you want a second opinion on.
An AI weighs in
An AI model estimates how likely it's AI-generated and explains why. Run all three models together in the app.
Read the estimate
See a likelihood estimate, the AI's reasoning, and the signals it noticed.
Frequently asked questions
Is this proof that text is AI-generated?
No. AI detection is unreliable and produces false positives. Use it as a rough signal, never as proof or to accuse anyone.
Why a panel of models?
Different models notice different patterns. Your free check uses one AI; the full panel (Claude, GPT and Gemini) runs in the app, so you can see where they agree and disagree.
Is it free?
Your first check is free. For unlimited use and the full three-model panel, subscribe to Pro.
