What is NotebookLM?

NotebookLM takes a different approach to chat: instead of answering from the open web, it answers only from sources you give it. Upload PDFs, paste links, add notes or slide decks, and it becomes an expert on your material, answering questions with citations that point to the exact passage in your documents. Students, researchers and analysts use it to interrogate large reading piles without losing track of evidence.

Its signature trick is Audio Overviews, which convert your sources into a surprisingly natural podcast-style discussion between two hosts — a genuinely new way to absorb dense material on a walk. Study guides, timelines, briefings and mind maps generate from the same sources in one click. The free tier is generous; a Plus tier adds bigger notebooks and more audio generations.
