What you get for free
- A Verdict in plain words: Likely human, Unclear or Likely AI.
- The passages behind it, highlighted in your text, with a confidence for each.
- A link you can share that shows the result without showing your text.
- 5,000 words a month without an account, 10,000 with a free one.
Why the free version is honest
Many free detectors show one big percentage and leave you to guess what it means. We show a Band whose thresholds we measured on thousands of texts, and we publish the error rates, including where the detector struggles. If a text is borderline, we say Unclear rather than pretend.
Need more? Pro scans 300,000 words a month, reads PDF and Word files, and makes reports.
Questions
Is it really free?
Yes. Without an account you can scan 5,000 words a month, up to 1,500 words at a time. A free account doubles that to 10,000 words a month and keeps your history. There is no trial that turns into a charge.
What is the catch?
There is no advertising and no selling of your text, because we do not keep it. Pro exists for people who need more words, file uploads and reports; that is how the free plan is paid for.
Is the free version less accurate?
No. Free and Pro Scans use the same Engine and the same thresholds. Pro adds volume and features, not a better answer.
