NotebookLM
A Google tool that turns your own documents into a single source of truth: it answers using only that information, without making up data from the internet.
Quick guide
NotebookLM is Google's AI research assistant that analyzes documents you upload (PDFs, web pages, audio, video) and generates summaries, mind maps, audio podcasts, and now autonomous research reports based exclusively on those sources.
Turning a set of your own documents into summaries, Q&A, podcast-style audio summaries, data tables, and presentations, all grounded in the sources you uploaded to minimize hallucinations.
When you need to study, research, or synthesize many of your own documents (notes, reports, papers) and want answers grounded in those sources instead of a chatbot's generic knowledge.
- Go to notebooklm.google.com with your Google account (free plan available)
- Create a notebook and upload your sources: PDFs, links, audio, or video
- Request summaries, mind maps, or generate a podcast-style audio summary of the sources
- Use the chat to ask questions that get answered by citing your documents directly
Free (Standard) with daily limits; Plus $7.99/month; Pro $19.99/month (300 sources per notebook, 20 Deep Research reports/day); Ultra starting at $99.99/month with advanced autonomous agent features.
