In more detail
NotebookLM's Audio Overview turns the sources in any notebook into a podcast-style audio conversation. Two AI hosts discuss the material naturally — one introduces topics, the other asks clarifying questions, they joke and build on each other. Generation takes 2-5 minutes. Free tier: 3 per day. Plus tier: 15 per day plus customization (tone, focus, length, audience). It is the fastest way to absorb dense reading lists during commutes, walks, or workouts. Many researchers consider it NotebookLM's breakout feature.
