OpenAI Adds Text Watermarking to ChatGPT in the EU Under AI Act Rules

WHY IT MATTERS

When you read something online, it can be hard to tell whether a person or an AI wrote it. Watermarking is like an invisible stamp placed inside AI-generated text — you cannot see it with your eyes, but a special tool can detect it. The EU has passed a law called the AI Act that requires companies making AI tools to help people identify when content was created by AI. Think of it like how food labels tell you what ingredients are inside — the watermark is meant to give readers a way to know what they are consuming. This matters for the crypto world because AI-generated content is increasingly used in news, social media, and research that can influence how people think about markets and investments. Knowing whether content is human- or AI-written could help readers evaluate the information they rely on.
