Anthropic introduces watermarking for AI-generated text in Claude
AI company Anthropic is introducing invisible watermarking for text created by its Claude model. The system allows for statistical verification of whether a text was generated by the platform.

What happened?
Anthropic is introducing a watermarking feature for AI-generated text within its Claude platform. The system functions by influencing how words and characters are selected during text generation in a manner that remains invisible to human readers. This unique structure enables dedicated tools to identify whether a text was created by Claude.

Why it matters
The initiative responds to increasing demands for traceability and protection against the misuse of AI-generated text, such as in cases of disinformation or copyright disputes. Watermarking makes it possible to identify material without altering the text's readability or quality for the end user.
Who is affected?
The feature concerns developers, businesses, and public sector entities using Claude for text generation. It also affects readers and reviewers who need to verify the origin of AI-generated material.
Impact on the EU
The European Commission and member states are encouraging transparency regarding AI-generated content under the EU AI Act. Anthropic's watermarking is available globally as it is built into the generation mechanism of the Claude models.
What else you should know
The method of invisible watermarking is more robust against text changes than simple keyword filters, though it faces technical limitations if the text is significantly rewritten. The watermarking complements Anthropic's existing safety and transparency measures.
