How the watermark holds up
We applied our AI watermark to the image below. You can't see it but it survives all 11 real‑world attacks.
Then we put it through this
Each copy went through a real‑world attack before we attempted to recover it, shown alongside the untouched original.
AI recovered the original watermark in 11 of 11 cases. Standard managed 4.

Heads up: the AI model runs on a server that shuts down when not in use, so the first check after a quiet spell might take a minute or two to start the server.
