Anthropic explains how Claude’s invisible text watermarks will work
The Verge • 8/17/2026
Summary
Anthropic has announced plans to implement invisible watermarks in text generated by Claude to comply with Europe's AI transparency rules. The text marking system is based on a version of the SynthID-Text approach, an open-source watermarking technology developed by Google DeepMind that utilizes detectable patterns from wording probabilities. This watermarking feature, along with C2PA support for images processed by Claude, is being introduced to fulfill obligations under the European Union's AI Act, which mandates that synthetic audio, image, video, and text include machine-readable marks.
