NotebookLM is Google’s AI research and thinking partner that grounds its answers in your uploaded sources, generating summaries, study guides and even audio overviews.
NotebookLM lets you upload documents, links, videos and notes into a notebook, then interact with an AI that only answers from those sources with citations. Its breakthrough feature, Audio Overview, turns your material into a podcast-style conversation between two AI hosts.
NotebookLM supports mind maps, study guides, briefing docs and chat across dozens of sources, and its Studio features expand into reports, presentations and video overviews. Because answers are grounded in your material with inline citations, it dramatically reduces hallucination for research and study work. Audio overviews make dense material approachable during commutes and workouts, turning dead time into learning time. Inline citations mean you can verify every claim against your own sources in one click.
NotebookLM is free for anyone with a Google account, with usage limits on audio and studio generations. Google AI subscriptions raise limits and unlock premium features, and enterprise access is available through Google Workspace. The free tier is remarkably generous, and subscriptions mainly matter for heavy generation of audio and studio outputs.
NotebookLM serves students, researchers, writers, analysts and teams who work intensively with source material and want an assistant that stays grounded in what they provide. It also suits book clubs, study groups and teams onboarding into complex domains together.
