Anthropic is officially embedding invisible, machine-readable watermarks into all Claude-generated text and files. Using C2PA standards and unique signal weaving, these digital signatures persist even through copy-pasting.

While designed for EU AI Act compliance, this global update tracks AI provenance across all platforms. Remember: a detected watermark proves Claude’s involvement, but it doesn't necessarily confirm the text is purely machine-authored.
