Tool profile
NotebookLM by Google
NotebookLM is an AI-powered research and note-taking tool that lets you upload your own documents, PDFs, websites, YouTube videos, and Google Docs, then ask questions and get answers grounded exclusively in those sources. It generates summaries, FAQs, study guides, and even AI audio overviews (podcast-style conversations) from your material. Unlike general chatbots, it will not hallucinate outside your uploaded content — it cites exactly where each answer comes from.
Models and pricing
Individuals doing personal research, studying, or experimenting with document-grounded AI
Supports up to 100 sources per notebook, up to 500,000 words per source, and 50 notebooks total. You get a limited number of audio overviews and queries per day. More than enough for most personal or light professional use — start here before paying anything.
Power users, professionals, and teams who hit the free tier's daily limits or need deeper customization
Increases query limits significantly (reportedly 5x more audio overviews and queries than free), adds the ability to customize the AI's response style, and unlocks usage analytics. The subscription bundles Gemini Advanced, so if you already want that, NotebookLM Plus comes along at no extra cost — good value. If you only want NotebookLM, weigh whether the limits actually bother you first.
Businesses and enterprise teams deploying it across an organization with admin controls and data governance
Adds enterprise data protections (your data is not used to train Google models), admin controls, and team collaboration features. Pricing varies by contract. If data privacy for sensitive business documents is a concern, this is the version to ask about — do not just use the free consumer tier with confidential files.
Which model should you use?
Almost everyone should start with the free tier — it is genuinely capable and the limits are not punishing for typical use; only upgrade to Plus if you regularly hit daily query caps or need the audio overview volume increase and the bundled Gemini Advanced makes the $19.99 feel justified.
