What is Gemini Notebook?
Gemini Notebook (formerly NotebookLM) is Google's source-grounded AI research notebook. You upload sources — PDFs, web URLs, YouTube videos, Google Docs, audio files — and it answers questions about them with inline citations. Unlike a general chatbot, it only draws from materials you provide, making its answers verifiable.
In more detail
Gemini Notebook (formerly NotebookLM) is a free AI research tool from Google, renamed in July 2026 as part of the Gemini brand consolidation. The core idea is unchanged: AI that only answers from sources you upload. Add up to 300 sources per notebook on the free tier (1,500 on the paid tier). Ask questions; get cited answers. Notable features include Audio Overviews (podcast-style summaries of your sources), Mind Maps, Briefing Docs, and Study Guides. Gemini Notebook is free with a Google account; the paid tier ($19.99/month via Google One AI Premium) raises limits and adds team sharing. Gemini Notebook Toolkit is the leading Chrome extension that adds one-click capture from 30+ platforms into Gemini Notebook.
