Anthropic Details How Claude's Invisible Text Watermarks Will Work

In one line: Anthropic has publicly described how it will embed watermarks that are invisible to human readers into text produced by Claude, according to The Verge.

Key points

• The focus is on generated text rather than images — markers that let Claude's output be identified after the fact.
• The watermarks reportedly stay hidden during normal reading and are detectable only through dedicated verification tools.
• The stated motivation is tracing the provenance of AI content and countering misuse such as plagiarism and disinformation.
