NotebookLM

Google

Google's AI research and note-taking assistant that grounds answers in your own sources and turns them into Audio Overviews (AI podcasts).

Product preview

Overview

NotebookLM is Google's grounded research assistant: you feed it your sources — documents, PDFs, videos, websites — and it answers strictly from that material with inline citations, never drifting into general internet guesses. Every claim links back to the exact passage it came from.

Its killer feature is the Audio Overview: two AI hosts discuss your sources in a surprisingly natural podcast — an unexpectedly effective way to absorb material. For students, analysts and researchers, it has become the trusted way to interrogate a body of knowledge rather than search it.
