Google-NotebookLM fires when a NotebookLM user pastes your URL as a source for their notebook - the tool fetches the page so the user's AI workspace can summarize, cite, and answer questions about it.

Google classifies it as a user-triggered fetcher, and its documentation states these fetchers generally ignore robots.txt because the request originates from a person, not an automatic crawl. To enforce a block, filter the user-agent at the server or firewall level.

Allow Google-NotebookLM

People actively studying your content in NotebookLM get answers grounded in the real page - high-intent engagement with your material.

User-agent: Google-NotebookLM
Allow: /

Block Google-NotebookLM

You don't want your content imported into third-party AI workspaces - but note a robots.txt rule alone won't stop it.

User-agent: Google-NotebookLM
Disallow: /

Heads up: Google-NotebookLM does not reliably honor robots.txt. To enforce a block, combine the rule above with server- or firewall-level filtering of the user-agent.
