Heads up if you use Claude or any AI tool in your content: this week Anthropic started embedding an invisible watermark into every piece of text Claude generates and as this was written by Claude it probably has one! Here's what's actually happening. The EU passed a law called the AI Act that requires AI companies to mark generated content so it can be detected later. Anthropic rolled that out this week, and it applies everywhere, not just Europe. It's baked into the text itself, invisible to you and me, and it can survive copy and paste into your blog, your Skool posts, wherever you put it. I want to be clear about what this is and isn't. It is not a quality flag. It doesn't mean your content is somehow less legitimate because AI touched it. If you're bringing your own ideas, your own judgment, your own story, and using AI to help with phrasing, that is still your work. I have been saying this for months and I still believe it. The watermark doesn't change that. It is a paper trail. If you generate a full draft with AI and barely touch it, that mark is designed to survive. If you write it yourself and use AI to tighten a paragraph here or there, heavy editing dilutes or removes the signal. So the more the words are actually yours, the less this affects you. Google's Gemini has been doing something similar for a while. ChatGPT has said it's building the same thing but hasn't shipped it yet. Not every AI tool does this right now, but the direction is clear. This is where the whole industry is headed because the law requires it, not because one company decided to. Here's my honest take, and here's why I'm telling you this now. I use AI every day in my business. I always have my own ideas first, I always know whether what comes back is any good, and I use AI to help the language land. That's not going anywhere. But this is a good moment to ask yourself where your line is. How much of what you publish is actually your voice, and how much are you outsourcing entirely.
