Nurit
For site owners
NuritBrowse is the browser used by Nurit, a personal assistant app, when a person asks it to look something up or check a page for them.
It always says who it is, and it never tries to get past bot checks or CAPTCHAs.
When a person directs it live, it stops and hands the page back to them if your robots.txt names Nurit or disallows everything, or if you refuse the request. When Nurit checks pages on its own, it follows every robots.txt rule.
To block it
