Direct answer
What is NotebookLM?
NotebookLM lets you upload documents, links, and videos, then answers questions strictly from those sources with citations and can generate audio and video overviews, study guides, and mind maps.
Each notebook holds up to dozens of sources; answers cite passages and refuse to stray beyond the material, which reduces fabrication. Audio Overviews turn sources into a podcast-style discussion, and additional outputs include briefing docs, FAQs, timelines, and mind maps. Sharing lets teams build notebooks together.
Strict grounding in your own sources with inline citations, plus distinctive audio overviews for learning on the go.
