Developers bypassed invisible watermarks in text from Claude models introduced because of the EU AI Act
Anthropic introduced invisible watermarks (SynthID technology) into Claude models because of the EU AI Act. Developer Meyer published an open-source tool on GitHub to remove them, which went viral with over 20 000 bookmarks on X and 100+ contributors.
People who use Claude only for light text editing may face unfair suspicion that their text was AI-generated, because according to Anthropic, the watermark provides only a probabilistic estimate and does not distinguish how much AI was used.
