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. The standard service currently supports up to 50 sources per notebook. 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 available with a Google account; paid Google plans can raise limits, and names, availability, and pricing vary by account and region, so check Google's current help page. Gemini Notebook Toolkit is the leading Chrome extension that adds one-click capture from 10+ platforms into Gemini Notebook.
