About

NotebookLM is a free-to-access AI research and note-taking assistant from Google that helps people understand complex material by working directly from the sources they upload. Instead of answering from the open web, it grounds its responses in documents, notes, and files the user chooses, which reduces irrelevant output and makes the results easier to verify.

The product is built with Google's Gemini models and operates as a "research and thinking partner": users add their own material, then ask questions, request summaries, or convert the content into other formats such as slide decks, mind maps, and audio or video overviews. Because every answer traces back to the user's selected sources, NotebookLM suits anyone who needs trustworthy analysis of specific texts rather than general chatbot conversation. It is available through a web app at notebooklm.google.com, with sign-in via a Google account.

Key Features

Grounded answers from your own sources: NotebookLM bases its summaries and answers on the documents the user uploads rather than on open-web content, keeping responses tied to trusted material.
Built on Gemini models: The assistant uses Google's current Gemini large language models to process and reason over the user's sources.
Source-to-slide-deck conversion: Users can turn uploaded files into presentation slides, cutting down the manual work of building decks from long documents.
Mind maps from brainstorms: The tool converts scattered notes and ideas into structured mind maps, helping users see relationships between concepts.
Audio Overviews: Assignments and documents can be transformed into audio overviews, letting users listen to a synthesized discussion of their material.
Video Overviews: Textbooks and other sources can be turned into video overviews, offering a visual way to review dense content.
Web and mobile app access: NotebookLM is available through the browser at notebooklm.google.com and offers an app for use on the go.
