Visit NotebookLM →About NotebookLM
NotebookLM is a research and note-taking tool from Google. You upload your own material — PDFs, documents, slides, web pages, notes — and it answers questions, summarizes, and builds study aids using only those sources, with citations back to the original text.
The big change came on June 8, 2026, when the "NotebookLM 2.0" upgrade rolled out globally. The product now runs on Gemini 3.5 (plus Google's "Antigravity" models) and has shifted from a static document Q&A tool into a more agentic research assistant. Google reports roughly a 65% average win rate over the previous version, and higher scores on large-document analysis and source discovery.
Capabilities expanded considerably. Each notebook now gets a secure cloud computer that can write and execute code natively for data analysis, drawing on 100+ curated software skills. You can export to editable PDFs with charts and tables, PowerPoint, Excel, and CSV/JSON, and generate images. Video Overviews now sit alongside the familiar Audio Overviews and podcast-style summaries, and integrated web search lets you start a project from an idea rather than only from files you already have.
Pricing is tiered. There is a free Standard tier at $0, then Plus at $7.99/mo (Google AI Plus), Pro at $19.99/mo (Google AI Pro), and Ultra at $99.99/mo and $200/mo (Google AI Ultra). NotebookLM is sold only as part of a Google AI, Workspace, or Cloud plan — you cannot buy it on its own.
The main caveats: the most advanced features were initially gated to the AI Ultra and Workspace business tiers, so the free plan is more limited than the headline announcements suggest. And because answers are grounded in your uploaded sources, the tool is only as good as the material you give it.
It suits students, researchers, analysts, and knowledge workers who need reliable, cited answers over a defined body of documents rather than open-ended web chat.

- Exports to editable PDF, PowerPoint, Excel, CSV/JSON plus Audio and Video Overviews
- Free Standard tier lets you try the core research workflow at no cost
- Integrated web search means you can start a notebook from an idea, not just pre-loaded files
- The most advanced features were initially limited to AI Ultra and Workspace business tiers
- Cannot be bought standalone — you need a Google AI, Workspace, or Cloud plan
- Answer quality depends entirely on the sources you upload
