QUICK ANSWERS
Yes. All current detection features are free to use without registration, login, a credit card, or purchased word credits. Each check supports up to 10,000 characters.
It is not uploaded to a detection server. Pasted or imported text is analyzed in your current browser. The site only loads the website and resources required for analysis. Local history can be cleared at any time.
It can flag model and statistical signals associated with AI-assisted writing, but it cannot reliably identify a specific vendor or model. Treat the result as a review signal, not final proof of authorship.
The detector supports Chinese, English, and mixed-language text. Paste text directly or parse TXT, Markdown, DOCX, and text-based PDF files locally in the browser.
No. Every AI-text detector can produce false positives and false negatives. Short, translated, formula-heavy, code-heavy, and domain-specific writing needs extra caution. Review drafts, revision history, sources, and human evidence together.
