Gemini Notebook, called NotebookLM until July 2026, is Google's research and thinking assistant. It bases its answers on sources you provide and is built on Gemini models. According to Google, it turns files into slide decks, brainstorms into mind maps, and assignments or textbooks into audio and video overviews; each notebook can also execute code for data analysis. Signing in with a Google account is required. It is a cloud service for web and mobile, available to Workspace customers and personal accounts, with a separate Enterprise edition on Google Cloud.
Google LLC is a US company based in Mountain View, California, so the service falls under US jurisdiction, including the CLOUD Act. For the Enterprise edition, Google documents at-rest storage and machine-learning processing in the us and eu multi-regions, except for the Discover Sources feature. For the consumer and Workspace editions, Google documents no comparable data-residency commitment. A European organisation that requires EU processing should therefore choose the Enterprise edition with the eu multi-region and review the terms. The service is proprietary.
