\u201cWhen a supported Claude model generates text, it weaves an imperceptible watermark directly into the text itself,\u201d the company\u2019s website said. \u201cYou won\u2019t see it, and it doesn\u2019t change the meaning, quality, or readability of Claude\u2019s response.\u201d<\/p>\n
Anthropic added that the watermarks will \u201ctravel with the text when it\u2019s copied and pasted elsewhere, and may persist through some editing.\u201d<\/p>\n
The watermarks will be implemented \u201cwherever Claude is offered, worldwide,\u201d including within the Claude Platform API, Claude Code, Claude Cowork and Claude Tag.<\/p>\n
Anthropic acknowledged that its detection program has \u201climitations\u201d and may not always identify AI-generated content, especially in cases where text has been \u201cheavily edited, paraphrased, translated, or mixed into other writing\u201d or the \u201cpassage is very short.\u201d<\/p>\n
The European Commission, the EU\u2019s digital watchdog, has said it had \u201cstrong backing\u201d from the tech industry in its push to clearly label AI-generated content so that users aren\u2019t misled.<\/p>\n
As of July 31, the EU had secured commitments from nearly 200 companies to comply with its transparency rules. <\/p>\n

Aside from Anthropic, AI giants like Sam Altman\u2019s OpenAI, Mark Zuckerberg\u2019s Meta, Google and Microsoft all signed on to the pledge.<\/p>\n
\u201cBy signing the code, providers and deployers of generative AI systems signal their intention to promote public trust in AI and to mitigate deception and misinformation,\u201d the EU said in a press release<\/a>.<\/p>\n The efforts by Anthropic and other companies come amid heightened concerns about the rise of so-called \u201cAI slop\u201d and AI-generated content being passed off as authentic.<\/p>\n Last month, a debut novelist\u2019s $2 million book deal was canceled<\/a> after a publisher became concerned that he had used AI to write the manuscript.<\/p>\n Still, Anthropic\u2019s new policy irked some commenters, with one calling it \u201ctotal bulls\u2013t.\u201d<\/a><\/p>\n Others pointed out that tech-savvy consumers may be able to find workarounds.<\/p>\n
