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.

Made byGoogle
Launched2023
CategoryAI Research & Note-Taking Assistant
Best forStudents and researchers who need to interrogate a specific set of documents without the AI hallucinating outside sources; professionals who want to quickly digest long reports, legal filings, or technical manuals; anyone who wants to turn a pile of PDFs into a structured study guide or podcast-style summary.
PricingNotebookLM is free; NotebookLM Plus is available via Google One AI Premium at $19.99/month or through Google Workspace plans.

Models and pricing

NotebookLM (Free)Free

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.

NotebookLM Plus (via Google One AI Premium)$19.99/month (Google One AI Premium subscription, which also includes Gemini Advanced)

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.

NotebookLM Plus (via Google Workspace)Included in select Google Workspace plans; exact pricing depends on Workspace tier — Google has not published a standalone add-on price as of mid-2025

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.
