Anthropic Implements Invisible Watermarks in Claude AI-Generated Text and Files
Anthropic has introduced invisible watermarks in all text and files generated by its Claude AI models starting August 2, 2026. These machine-readable marks, compliant with the EU's AI Act transparency requirements, embed directly into text without affecting readability and persist through copying and some editing. For files like images, digitally signed provenance metadata will indicate AI generation and detect tampering. This system applies across Claude's products globally and aims to improve transparency about AI-generated content.
