AI Text Watermark Checker 作者： AI Text Watermark Checker

AI Text Watermark Checker inspects selected text and supported AI chat pages for hidden Unicode, zero-width characters, direction controls, special spaces, and related formatting artifacts. Scanning and cleaning happen locally in Firefox. The extension reports exact code points and removes only supported literal artifacts without rewriting readable wording. It does not claim that hidden characters prove AI authorship or that generic cleaning defeats provider-level statistical watermarks. Users can scan selected text, scan supported page content, copy a cleaned result, or open the full web scanner for file and batch workflows.
