notebooklm capabilities

Audio Overviews are AI-generated audio conversations between two AI hosts that summarize and discuss the key topics from the notebook's sources, available in four conversational formats and 80+ languages.

NotebookLM offers a curated gallery of publicly shared 'featured notebooks' created by Google and third parties, letting any signed-in user explore pre-loaded research notebooks without adding their own sources.

NotebookLM generates interactive flashcard decks and quizzes from notebook sources as study aids, with per-session progress tracking and difficulty customization.

NotebookLM generates interactive mind maps from notebook sources, visualizing main topics and their relationships as an expandable branching diagram in the Studio panel.

NotebookLM has dedicated native mobile apps for iOS (17+) and Android (10+) that bring core notebook functionality to phones and tablets, with some Studio outputs not yet available on mobile.

NotebookLM's Notes feature lets users write free-form notes in the Studio panel and save valuable AI chat responses as persistent notes, up to 1,000 per notebook.

NotebookLM is not sold standalone; it is bundled into Google AI subscription plans (Standard free through Ultra) and qualifying Google Workspace plans, with usage limits scaling by tier.

NotebookLM does not use notebook content to directly train foundational AI models; privacy protections differ between personal Google accounts and Google Workspace or Education accounts.

Notebooks can be shared privately with named collaborators (Viewer or Editor) or made publicly accessible to any Google account holder via a link, enabling read-only or co-editing access to sources, notes, and Studio outputs.

NotebookLM accepts a wide range of source types that become the grounding material for all chat and Studio outputs. Supported formats span local files, cloud documents, URLs, and media.

NotebookLM's chat interface answers questions exclusively using the sources uploaded to the notebook, providing inline citations for every claim so users can verify the original passage. Responses are not generated from general world knowledge.

The Studio panel generates structured text documents from notebook sources in one click, including study guides, briefing documents, FAQs, and timelines, collectively called Reports in the current UI.

NotebookLM is powered by Google's Gemini model family; the specific model tier served depends on the user's subscription plan, with Gemini 2.5 Flash as the baseline for free accounts.

Video Overviews are AI-generated videos that transform notebook sources into visual presentations, ranging from narrated explainers to cinematic deep-dives with animations.
