ANTHROPIC'S CLAUDE WILL ADD WATERMARKS TO AI-GENERATED TEXT AND FILES

Summary from the TLDR Marketing newsletter

Anthropic is adding invisible watermarks to Claude-generated text and files, including images, to comply with EU transparency rules and help identify AI-generated content. The markers are designed to survive copying and editing, while images will include provenance metadata that can reveal tampering. The system has limits, since heavy editing, paraphrasing, translation, or screenshots can remove or prevent watermarks.
