🙂 Anthropic Adds Invisible Watermarks to Claude Answers

Anthropic has begun embedding invisible, machine-readable watermarks directly into text generated by its Claude AI models, a move driven by new transparency requirements under the EU AI Act.

The company detailed the system in a support page published this month, confirming that Claude models launched on or after August 2, 2026 support machine-readable marking from launch.

Should AI-generated content be labeled?

❤️ — Yes, absolutely!
🔥 — No, it's useless
