Claude's AI watermarks are coming, but AI detectors aren't going anywhere

Claude's AI watermarks are coming, but AI detectors aren't going anywhere AI text watermarks and AI writing detectors may sound like the same thing, but they do very different jobs. Regular "Prompt Mode" readers already know that Claude AI watermarks are coming, and that they'll allow us to tell whether a given piece of text was either written or otherwise "processed" by Claude. But here's a question I've been getting a lot lately: With Claude watermarks on the way, do we still need AI writing detectors? Of course, if we asked that questions to GPTZero, Originality.ai, Copyleaks, Turnitin, or any of the popular AI detection services with paid tiers, they'd surely say "yes."
