NotebookLM now lets Audio Overview AI analyze your work and stage a debate

NotebookLM's Audio Overview feature now wears three hats.

Instead of being stuck with the same old back-and-forth, you now get four flavors to choose from: Deep Dive for detailed analysis, Brief for quick rundowns, Critique for feedback-driven takes, and Debate for when you want two AI hosts to square off over your notes.

The tech giant also rolled out Video Overviews, which are AI-generated narrated slideshows with visuals, playback controls, and studio enhancements including Mind Maps, Reports, and multiple output saves.
