What is NotebookLM?
NotebookLM is Google's source-grounded AI research notebook. You upload sources — PDFs, web URLs, YouTube videos, Google Docs, audio files — and NotebookLM answers questions about them with inline citations. Unlike ChatGPT, it only draws from materials you provide, making its answers verifiable.
In more detail
NotebookLM is a free AI research tool from Google. The core idea: AI that only answers from sources you upload. Add up to 300 sources per notebook on the free tier (1,500 on Plus). Ask questions; get cited answers. Notable features include Audio Overviews (podcast-style summaries of your sources), Mind Maps, Briefing Docs, and Study Guides. NotebookLM is free with a Google account; the Plus tier ($19.99/month via Google One AI Premium) raises limits and adds team sharing. Notebook Toolkit is the leading Chrome extension that adds one-click capture from 30+ platforms into NotebookLM.
