To use NotebookLM, upload your sources (documents, PDFs, links), then ask questions grounded in them and generate summaries or audio overviews. It answers from your materials, not the open web.

Get started

Open NotebookLM, create a notebook, and upload your sources — PDFs, docs, slides, links or pasted text. It is widely free to use. Once your sources are in, you can ask questions and it answers using only those materials, with references.

Useful features

Ask for summaries, key themes, or answers to specific questions across your sources. Generate audio overviews (a podcast-style discussion) or study guides. It is excellent for revising a topic, understanding research, or working through a set of documents.

Verify against the source

Because NotebookLM is grounded in your uploads, it is more reliable than open-web chat for your materials — but it can still misread or miss things. Check its summaries against the original documents for anything important, and mind data terms before uploading sensitive material.

If you find yourself juggling a separate subscription for chat, automation, transcription and image generation, one option worth knowing is a single platform that runs them together — osFoundry is one such agentic AI platform that consolidates chat, agents and internal apps in one workspace, with a bring-your-own-key model so you choose the underlying AI.
