What is Google-GeminiNotebook?
Google-GeminiNotebook is Google's user-triggered fetcher. A user-triggered fetcher runs when a person asks an AI product to open a page, not on a schedule. From the operator's wording: URLs users add as notebook sources.

How do I opt out of Google training but stay in its search?
Each Google user agent has its own token, so you can set them one by one. This file blocks Google-Extended and allows Googlebot. Every line comes from the rows in this dataset. Whether allowing a bot keeps you in a product is Google's call, so check each crawler's page.
User-agent: Google-Extended
Disallow: /

Each other Google user agent has its own robots.txt token, so a rule for Google-GeminiNotebook does not cover them. See the related crawlers below.
Does Google-GeminiNotebook follow robots.txt?
No. Google: user-triggered fetchers generally ignore robots.txt. Google user-triggered fetchers page: they 'generally ignore robots.txt rules'.
Robots.txt is a request, not a lock (RFC 9309).
What IP addresses does Google-GeminiNotebook use?
Google publishes a list at https://developers.google.com/static/crawling/ipranges/user-triggered-fetchers-google.json. We did not download or parse it. A request that claims to be Google-GeminiNotebook but comes from outside that list is not Google-GeminiNotebook.
