AI text watermark: why Claude and ChatGPT text may now carry a hidden mark

Under the EU AI Act, AI-written text from Claude and ChatGPT is starting to carry an invisible watermark. You can't see it, and it doesn't change the words.

Can AI text watermarks be detected? Only by the company that added them, using its own tools. Heavy editing weakens them, and no watermark proves a human wrote the text.
