All models released after that date will automatically watermark text and files (using the C2PA open standard for files). The watermark travels with copied and pasted text and persists through some editing. Older models will also receive watermarking support. The move is part of a broader industry trend, with companies like Google, Meta, Microsoft, and OpenAI also committing to the EU's transparency code. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How does Anthropic watermark text generated by Claude and does it survive copy-paste? Anthropic embeds the watermark directly in the generated text, so it travels with the content when copied and pasted and may persist through some editing. For files, Anthropic uses the C2PA open standard. Watermarking is applied at the model level, meaning it is present regardless of which Claude product or API surface produces the text. All models released after August 2 include this automatically; older models will receive it retroactively. _Developers integrating Claude into products can track watermarking and compliance updates on daily.dev._ ### What does the EU AI Act Transparency Code require for AI-generated text? The EU AI Act's Transparency Code, which took effect August 2, requires AI companies to mark AI-generated or edited content in a way that other systems can identify. Companies including Anthropic, Google, Meta, Microsoft, and OpenAI have committed to adhering to the code. For files, the C2PA open standard is a common implementation approach. _Teams navigating EU AI Act compliance requirements find the latest industry moves covered on daily.dev._ --- Tags: [#claude](https://daily.dev/tags/claude), [#anthropic](https://daily.dev/tags/anthropic), [#ai-governance](https://daily.dev/tags/ai-governance) [View this post on daily.dev](https://daily.dev/posts/anthropic-says-it-will-watermark-text-generated-by-its-ai-models-emyimuavf) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Anthropic says it will watermark text generated by its AI models","url":"https://daily.dev/posts/anthropic-says-it-will-watermark-text-generated-by-its-ai-models-emyimuavf","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/anthropic-says-it-will-watermark-text-generated-by-its-ai-models-emyimuavf"},"datePublished":"2026-08-11T12:15:17.352Z","dateModified":"2026-08-11T12:16:18.672Z","description":"Anthropic will watermark text generated by its AI models, including Claude, to comply with the EU AI Act's Transparency Code that took effect August 2.
