The gist

Anthropic began watermarking all Claude text outputs on August 2, 2026. Users are canceling subscriptions over fears of AI-labeling.

Background

Anthropic, the maker of Claude, announced that all Claude models would embed an invisible watermark in generated text to comply with the EU AI Act's transparency requirements. The watermark is designed to be imperceptible but detectable, using a technique called SynthID-Text. This move has sparked debate among users and developers, with some concerned about the implications for authorship and privacy.
