OpenAI will start watermarking ChatGPT’s text in the EU

# OpenAI Will Add Hidden Marks to ChatGPT Content in Europe OpenAI is adding invisible watermarks to text generated by ChatGPT in the European Union to follow new AI regulations there. Think of it like a digital fingerprint that proves the content came from AI rather than a human—helping people and organizations tell the difference. The watermark will be subtle enough that even editing the text won't completely erase it.
