AI watermark removal tool watermarks-remover hits 11k stars on GitHub, cracked Anthropic's watermark just days after release The open-source tool watermarks-remover has gained around 11k stars on GitHub. This tool can remove provenance marks from AI-generated content by multiple vendors, including hidden Unicode characters, statistical watermarks, and C2PA metadata in PNG/JPEG/SVG/PDF/DOCX/HTML/Markdown files. The timing of the tool's release is sensitive: just last week, Anthropic announced the addition of machine-readable watermarks to text generated by Claude to comply with the EU AI Act's transparency requirements, which took effect on August 2. watermarks-remover supports removing watermarks from Claude, Gemini/SynthID, OpenAI, and more. Twitter user Chubby commented: 'People really hate watermarks, and I totally get it.'
