Tool profile
NotebookLM by Google
NotebookLM lets you upload your own documents, PDFs, URLs, YouTube videos, and Google Docs, then ask questions and get answers grounded strictly in those sources. It summarizes, finds connections, and generates study guides or briefing documents based only on what you feed it. It also generates audio overviews — a two-host podcast-style discussion of your source material.
Models and pricing
Individual users doing personal research, studying, or light professional document analysis
Supports up to 50 notebooks, 50 sources per notebook, and up to 500,000 words per source. Includes chat, summaries, study guides, and audio overviews. Sufficient for most individual users — start here.
Power users who hit free-tier limits or need longer audio overviews and more notebooks
Offers roughly 5x higher usage limits than the free tier, longer and customizable audio overviews, and the ability to share notebooks with teams. Worth it if you regularly max out the free plan or need the audio feature for longer content. Note: the $19.99 bundles other Google AI perks beyond NotebookLM.
Teams and businesses that need shared notebooks and enterprise-grade access controls
Aimed at organizations already on Workspace. Allows admins to provision access across teams. If your company is already paying for Workspace, check whether your plan includes NotebookLM Plus before paying for Google One separately.
Which model should you use?
Almost everyone should start with the free tier — it covers most use cases with generous limits; only upgrade to Plus if you regularly need more than 50 notebooks, want customizable audio overviews, or need to collaborate with a team.
