Bilingual AI-Generated Content (AIGC) Detection

This site provides both the Chinese model version and the English model version. It follows your browser language by default, and you can switch versions manually on the homepage. The detector chunks long documents automatically and returns document-level, section-level, and high-risk snippet results with export support.
