Cardano Founder Launches New Free Tool to Remove Anthropic’s AI Watermark

Cardano founder Charles Hoskinson has published a free tool that removes Anthropic’s watermarks from Claude output. He named it Anthropies, a blend of Anthropic and herpes.

The project appeared on GitHub on Sunday, five days after Anthropic switched on invisible marking across every Claude product. Hoskinson shipped it under an Apache 2.0 license. How the Anthropic Watermark Actually Works Anthropic now marks Claude text at the model level.

The rollout answers the European Union AI Act transparency code, which took effect on Aug. 2. The mark is not a hidden character string. Instead, a secret key steers tournament sampling, a process that breaks ties between words fitting equally well. Anthropies.

Source: Hoskinson Github Hoskinson’s repository splits the problem into three layers. The “Co-Authored-By” git trailer strips out cleanly. C2PA credentials on images disappear after a re-encode. Prose is the hard layer.
