It can (and likely will) just transmit standard browser signals. The AI integration is more of a UI layer on top, not something that is being sent in a request header UA string.

That lack of signals in addition to the regular human behavior patterns that something like Puppeteer doesn't have is going to make this practically impossible to block

Because this browser is just chromium and its user agent will be indistinguishable

Bots can report such user agents too, so that's not the reason.

The reason is that it's easier to block bot hosting providers. That's why illegal botnets rely on compromised personal machines.

I downloaded it to see if Anubis can block it. It lies and claims to be Google Chrome.
