Anthropic Adds Invisible Watermark to AI Text; Tool Emerges to Remove It
Anthropic has introduced an invisible watermark in its AI-generated text from Claude to comply with the EU's AI Act transparency requirements. This watermark subtly influences word choice patterns, making AI-generated content detectable by those with the right key, without altering text visibly. However, Cardano founder Charles Hoskinson has developed a free tool that can remove these watermarks by rewriting the text through other models, raising questions about AI attribution and legal implications. The watermark does not add extra characters and aims to preserve content integrity.
