TechCrunch and social media users reacted angrily, worried that a persistent, undetectable-to-them marker could flag work or schoolwork as AI-generated even after editing.
“the backlash to Claude’s new text watermark is not about secret tracking but about authorship, quality and who bears the cost of an imperfect detection”

Maybe they're extremely clever with half-normalized unicode, but my hunch is: ``` # Ruby text = "[whatever claude gives you]" watermark_removed = text.gsub(/[[:space:]]+/u, ' ').gsub(/[\u200B-\u200D\uFEFF]/,'') ```

Huh... I wonder if some big version of a bloom filter would work as well. Hash all output text, probably in chunks of a couple tens of tokens each (that would need tweaking to find the most useful hash input length I guess), and smash 'em into a bloom filter. Every month or something, Anthropic releases a giant file containing whatever huge length…

Personally I wouldn’t have a problem if providing watermark removal was just made illegal, it’s not like AI forgery has all these legitimate use cases. You’d still have the issue of local models, but as you said, the important part is for it to be too much of a hassle for the average user. Also, worth noting that part of the point of steganography…

Especially when they say they'll let you use their tool to detect it, this just seems like a cat and mouse game. Have Claude write a long passage, then run it through another model with instructions to slightly paraphrase it. Ensure with the tool that it's no longer watermarked.Even if all models are mandated by EU to do their own watermarking, it…

To a point this technology has existed for a while. There’s tools in the software industry to try and fingerprint source code to find open source code that is not properly attributed, or outright license incompatible. Those tools need to handle not only simple copy/paste but also someone just going in and changing variable/function names. It’s…

I think it's definitely important that any AI generated content can be easily identified as such. I think the new EU law that requires that, has too many unnecessary exceptions.So great that Anthropic is doing something about this, but it's not clear what their watermark exactly is. How do I, as a user running into some content online, know that…

They’re both true at the same time. You do own the output. You just can’t copyright the raw output. You can do other things with the output that you own unrelated to copyright, such as commercial use. These are two different things. For commercial use, you need to own the content. That’s it. So you can put AI generated content (documentation…

John Gruber isn’t buying the Claude watermarking either: "What happens if you copy my text and quote it in something you write, by hand? Now you’ve got a watermark in your prose, invisible characters or something, that implicates that your prose is AI-generated? Even though you didn’t use AI and just copy and pasted text from me? Madness." Maybe…

>Content generated by Claude may not carry a detectable mark if, for example: ...>A file’s metadata was stripped through format conversion, re-saving, screenshots, or other meansAh. So what essentially every single consumer-oriented media host does. Gotcha.I fully recognise this is a hard problem, but hopefully metadata isn't the only method for…

This is something that already happens. For example, it’s extremely hard to implement instructions that force even GPT Sol 5.6 to avoid the structure “this is not … but …” or the usage of “;”, or even emojis. If this is how they intend to implement the watermarking, then it’s a very stupid way. I’d think a random combination of characters across…

Ben Thompson goes philosophical about the Claude watermarking : "What the E.U. is doing is stealing the last thing humans have — creation — and demanding it be bundled with substantiation, effectively giving AI the credit. That the human gave AI the text to proofread — or even the prompt to generate writing — doesn’t matter to the bureaucrats."…

Sure, there are things you could do legally when falsely accused; and there are things authorities and companies should do.But ultimately, when you are powerless and can't afford to do the fighting: I'm convinced the only way to protect yourself is to be very mindful about your writing style, and to deliberately corrupt the language through…

Editors who are not machines, and have original ideas of their own. Professional proofreaders who are capable of understanding the multiple layers of meaning within the full context of an author's work. AI is a shit replacement for those guys.
