Gemini Enterprise: Gemini Notebook Enterprise web address change

From 16 Nov 2026, Google removes lm from the hostname of the Gemini Notebook Enterprise web app. For Gemini Notebook Enterprise authenticated with Google Identity, notebooklm.cloud.google.com changes to notebook.cloud.google.com. For Gemini Notebook Enterprise authenticated with Workforce Identity Federation, notebooklm.cloud.google changes to notebook.cloud.google. The other change adds go/ to the URL path of the web app. Google's dates for the go/ path change give a start of 9 Nov 2026 for "All other locations". In both cases, existing links redirect automatically. Action is required if your organization uses a firewall, proxy, or secure web gateway that allows access to Gemini Notebook by a specific URL path. A Google release note of 12 Nov 2026 states that Gemini Notebook Enterprise is renamed to Gemini Notebook for business.

If your organization uses a firewall, proxy, or secure web gateway that allows access to Gemini Notebook by a specific URL path, Google recommends that you add these URLs to your allowlist:

1. Allowlist notebooklm.cloud.google.com/* and notebook.cloud.google.com/*.
2. If you use Workforce Identity Federation, allowlist notebooklm.cloud.google/* and notebook.cloud.google/*.
3. If you use Gemini Notebook within Gemini Enterprise, allowlist vertexaisearch.cloud.google.com/notebooklm/*.

Google recommends allowing entire domains (/*) so that future path changes do not require additional updates. If you do not allow /*, you must allow both /REGION and /go/REGION, where REGION is your location value. If your firewall blocks users before you update your allowlist, users can access the original URLs by removing /go from the URL and adding version=legacy. Google states that this workaround will fail when it sunsets the legacy version.
