Remove AI watermarks (SynthID and Claude)

Visit website

AI text is now getting watermarked by default: Google's SynthID, and now Claude (to meet the EU AI Act). Unmark removes both kinds of mark: it strips invisible Unicode characters (zero-width spaces, joiners, tag chars, homoglyphs) instantly in your browser, and rewrites the wording to disrupt statistical/SynthID-style watermarks. Everything for free without any login.

Hey! I made Unmark because watermarking AI text just went mainstream 😢. Anthropic announced Claude will watermark its output with a SynthID-style method by default. Two things it does: • Invisible characters are detected and stripped in your browser. • Statistical/SynthID watermarks are removed by rewriting, since they live in word choice, not hidden characters.
