This includes output from all models including Claude Platform (API), Claude, Claude Code, Claude Cowork, and Claude Tag. Generated text will have embedded watermarks, while generated files will include \"digitally signed provenance metadata where supported.\"\n\nNotably, it won't apply only to Europe; instead, the watermarks will appear wherever Claude is offered, worldwide, though Anthropic warns that some platforms or features may not support certain watermarking types.\n\n[Terms of Use](https://www.ziffdavis.com/terms-of-use)and\n\n[Privacy Policy](https://www.ziffdavis.com/ztg-privacy-policy).\n\nThe watermarks won't be visible if you don't know what you're looking for. For text files, the watermark will be \"part of the text\" and it will \"travel with the text when it's copied and pasted elsewhere,\" but Anthropic doesn't really go into the technicalities of how this will work. For files such as images, Anthropic will use the [Coalition for Content Provenance and Authenticity (C2PA) open standard](https://c2pa.org/). Details on how to recognize these watermarks will be shared in \"forthcoming documentation,\" wrote Anthropic.\n\nAs for existing models that were launched before Aug. 2, 2026 (that's pretty much all of them at writing time), Anthropic says it's working to add watermarking support to those as well.\n\nWatermarking won't be foolproof, warns Anthropic. For example, heavily edited, paraphrased, or translated text could not carry a detectable watermark, and a file's metadata could be stripped through format conversion, screenshots, or other means.\n\nAnthropic's move follows similar commitments by AI companies including OpenAI, Google, and Meta.\n\n*Want more tech and digital culture news delivered to your inbox daily or sent straight to your device?
