Unmark

What is Unmark?

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.
