  • Only the key-holder can check. Your teacher, editor, or favourite "AI detector" website cannot run this test; a genuine check needs the provider's secret key, or a checking service the provider runs. Google runs an early-access detector portal for SynthID; Anthropic says detection tooling is forthcoming.

I am not so sure about that. The amounts of words is finite and with enough text, you will see that certain words are used more often, especially in certain combinations. I believe people will brute force this and then create a way to destroy the watermark again.

Yeah, they can't easily rotate keys, because the text can't tell you which key was used.

They could switch to a new key e.g. every month and then just check every previous key during detection. But that would slowly increase the likelihood of false positives, so no idea if that's a good idea either.
