What is Google-GeminiNotebook?
It fetches individual URLs that Gemini Notebook users add as sources for their projects.
Fetches a page because a person asked an assistant about it, right now. Operators often say robots.txt does not apply to these user-triggered fetches.
It replaces the Google-NotebookLM user agent, which Google lists as supported until August 2026. Google says user-triggered fetchers generally ignore robots.txt because a user asked for the fetch.

Google documents these user agents for Google-GeminiNotebook. Version numbers in it change over time, so match on the name, not the whole string.

Usually allow it. Each fetch is a person asking about your page right now, which is close to a visit. Blocking it in robots.txt may not stop it, since operators often treat these fetches as the person’s own.
How to block Google-GeminiNotebook in robots.txt
Google says Google-GeminiNotebook does not follow robots.txt, so a robots.txt rule won’t stop it. Block it at your server or firewall by user agent, and by IP if Google publishes its ranges.
How to verify a request is really Google-GeminiNotebook
Anyone can send any user agent, so the string alone proves nothing.
Google publishes the IP ranges Google-GeminiNotebook crawls from. A request that claims to be Google-GeminiNotebook from any other address is not Google-GeminiNotebook.
Or check by reverse DNS: look up the hostname of the request’s IP, confirm it ends in google.com, then look that hostname up again and confirm it points back to the same IP.

Bots don’t run JavaScript analytics, so a script tag never sees them. invisit records crawler reads on the server instead, through its server SDK or a Cloudflare Worker, and shows which bots read which pages, next to your visitors.
