NotebookLM
Google's research assistant that answers from your own sources.
About NotebookLM
NotebookLM is Google’s source-grounded research assistant. You build a notebook from your own material — PDFs, Google Docs and Slides, web pages, YouTube videos, audio files, pasted text — and every answer is grounded in those sources with inline citations pointing at the exact passages. It is built on Gemini, and the Studio turns the same notebook into Audio Overviews (the podcast-style two-host summaries), Video Overviews, mind maps, flashcards, quizzes and briefing reports.
The free plan is unusually generous: 100 notebooks with 50 sources each, 50 chats a day and 3 Audio Overviews a day, with nothing but a Google account. Paid tiers are not a separate NotebookLM subscription — they ride on Google’s AI plans (Google AI Plus and Pro), which raise the limits up to 500 notebooks and 300 sources per notebook. (Google has also begun rebranding NotebookLM as Gemini Notebook; the product and the notebooklm.google address are unchanged.)
