NotebookLM

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.

Overview

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.
