Watermarking

Inside Claude’s Invisible Watermark — and the Subscriber Backlash It Triggered

AI company Anthropic has introduced an invisible watermark system for its Claude chatbot to comply with the EU's AI Act, which has led to backlash from some paid subscribers who are canceling their subscriptions. The watermark subtly influences word choices, making AI-generated text harder to pass off as human work, though it may not be effective on short texts or certain types of code. Despite user complaints and cancellations, Anthropic claims that overall cancellation rates have not significantly increased.
