Google NotebookLM

NotebookLM is Google's AI-powered research and note-taking tool. Instead of answering from the open web, it answers from sources you give it — you upload documents, PDFs, slides, pasted text, or links, and it becomes an assistant grounded in that specific material. It runs in a browser at notebooklm.google, signed in with a Google account.

Because it is anchored to your sources, it is strongest at making sense of material you already have: ask questions across a stack of documents, get summaries, pull out key points, and draft study or briefing notes — with answers that cite the exact passages they came from, so you can jump back to the original. Its well-known Audio Overview feature can turn your sources into a spoken, podcast-style discussion for review on the go.

It suits students working through readings, researchers synthesising papers, and professionals digesting reports, contracts, or documentation — anyone whose problem is too much to read rather than too little.

To begin, open notebooklm.google, sign in with a Google account, create a notebook, and add a few sources; there is no credit card for the free tier. It works best when you feed it the actual documents you care about.

The honest limits. Free notebooks have caps on the number of sources and their size, and a paid tier (offered through Google's AI plans) raises those limits. Because it is grounded in your sources it invents less about them, but it can still misread, so use the citations to check. Availability of specific features can vary by region and account type.
