FAQ
- Does it really search the web?
- Yes. The distinctive passages of the text are searched as exact phrases and every source shown is a real page with a link.
- Is it free?
- Yes: 1 check a day without an account, and far more with Premium. Each check runs real web searches, which is why the allowance is smaller than for other tools.
- Does it detect AI-written text?
- No, that is a different question. Use the AI detector for that; the two tools complement each other.
