guillaumemeyer/watermarks-remover appeared 2026-08-11 and gained 634 stars and 61 forks within 24 hours, targeting provenance marking from Anthropic, Google's SynthID-Text, OpenAI, and Kirchenbauer-style open-source implementations. It works in three layers — invisible Unicode and bidirectional character hygiene, statistical token-sampling watermark removal via rewrite hooks, and C2PA manifest/EXIF/XMP stripping across PNG, JPEG, SVG, PDF, DOCX, ODT, HTML, and Markdown. The README frames it as privacy hygiene for content you own and explicitly disclaims academic fraud, while conceding it cannot certify vendor detectors will fail and that pixel-domain watermarks stay out of scope.
