Anthropic’s ‘Watermark’ Text Adulteration in Claude Is a Perversion of Writing
Anthropic has introduced an invisible watermark to identify text generated by its Claude AI. Users cannot opt out of this system, which embeds identifiers into the output to distinguish AI-generated content from human writing. The move has sparked backlash, leading some users to cancel their subscriptions. While the watermark is currently invisible to the naked eye, it allows for the detection of AI-authored material. Anthropic has released technical details on the mechanism, though critics argue the practice alters the nature of writing.
