Claude now watermarks everything it writes. But it's not detecting AI writing, it's detecting LAZY AI writing. Anthropic just signed the EU AI Act and published how Claude marks its content. Think of it like the security thread in a banknote, you can't see it, but the right machine can. 1️⃣ Invisible watermark woven into the text. Travels with it when you copy-paste. 2️⃣ Images get a tamper-evident label that says "Claude touched this." 3️⃣ Works everywhere Claude runs: the app, the API, even through Amazon and Google. Paste raw Claude output into a court filing or client doc, it can now testify against you. Rewrite it? The watermark dies in the edit. You were already doing it right. This punishes lazy AI writing. Not AI writing. #ai #learnai #aitips #aitricks #aitools #claude #practicalyai
