ANTHROPIC TO START WATERMARKING CLAUDE-GENERATED TEXT, IMAGES

Summary from the TLDR Design newsletter

Anthropic will embed an invisible watermark in text and images generated by Claude, aligning it with the EU AI Act's voluntary Code of Practice. Text watermarking applies to Claude models released after August 2nd, and the mark persists when text is copied to other applications or edited. Images will be marked using C2PA metadata, though detection may fail on short or heavily edited text snippets.
