## 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-GeminiNotebook user agent

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

```
Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/138.0.0.0 Mobile Safari/537.36 (compatible; Google-GeminiNotebook; +https://developers.google.com/crawling/docs/crawlers-fetchers/google-gemininotebook)
Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/137.0.0.0 Safari/537.36 (compatible; Google-GeminiNotebook; +https://developers.google.com/crawling/docs/crawlers-fetchers/google-gemininotebook)
```

## Should you block Google-GeminiNotebook?

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.

## See when Google-GeminiNotebook reads your site

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.
