    "prose": "Anthropic announced on Monday that its new Claude models launching from 2 August will carry embedded watermarks undetectable to the human eye. [^1]\n\nA new online tool allows users to upload files to check for signs that the AI model Claude helped create or edit them. [^2]\n\nAnthropic said in a help document published on its website that generated text will carry embedded watermarks and generated files will include digitally signed provenance metadata where supported. [^3]\n\nAnthropic stated that the watermarks will be detected by machines if the text is copied and pasted from Claude, and some may survive editing. [^4]\n\nThe company stated that the move to add watermarks is a response to transparency requirements under Article 50 of the European Union's AI Act. [^5]\n\nIf the tool finds a C2PA credential that points to Claude, it will inform the user that the content was processed by the AI. [^6]\n\nThe tool checks for a C2PA content credential, which is a record attached to a file when it is made or edited to show what created or changed it. [^7]\n\nA missing signal from the tool does not confirm that the content was not made with Claude, as the signal might have been removed or the content produced by a model that does not support marking.
