Google-NotebookLM
Google · Unconfirmed Retired · robots.txt: Unconfirmed
Retired, in Google’s own words: “Former agent (supported until August 2026) Google-NotebookLM” (checked 2026-09-24). A robots.txt line naming Google-NotebookLM may do nothing: robots.txt only works through the names a crawler answers to, and Google lists this one only as a former agent.
Google's current token: Google-GeminiNotebook. Its page says what it does and whether it follows robots.txt. Keeping the old line next to it costs nothing.
Every fact below is unconfirmed by the operator: Google's documentation names this token only as a former agent, so this page states nothing about what it does. The robots.txt lines below are still correct syntax for it.
Block Google-NotebookLM
User-agent: Google-NotebookLM
Disallow: /
Unconfirmed by the operator Google's documentation we checked does not say what blocking Google-NotebookLM changes beyond the crawler itself.
Allow Google-NotebookLM
User-agent: Google-NotebookLM
Allow: /
An allow group only changes anything if a broader rule would block Google-NotebookLM. Under the robots.txt standard (RFC 9309, section 2.2.1) a crawler follows the group that names it and uses the User-agent: * group only when no group does — so this group lets it in even if your * group says Disallow: /. Token matching is case-insensitive.
Put these lines in /robots.txt at the root of each host (each subdomain has its own file). robots.txt is a request to well-behaved crawlers, not access control.
Already have a robots.txt? Paste it into the robots.txt checker to see whether it blocks Google-NotebookLM on a given path, and which line decides.

- In your server logs
- Unconfirmed by the operator Google's documentation we checked does not give its user-agent string.
