How to use NotebookLM

Getting started

To use NotebookLM, go to notebooklm.google and sign in with a Google account. After signing in, users land in a clean workspace with a menu for uploading and organizing notes, a toolbar, and a search bar.

Creating a notebook and adding sources

Users create a new notebook and add sources — up to 50 per notebook on the free plan. Supported formats include PDFs, YouTube links, Google Docs, audio files, websites, and text materials. After uploading, the AI answers questions strictly based on the content of the uploaded documents.

Generating content

After adding sources, you can click “Generate Audio Overview” to create a podcast in the form of a conversation between two AI hosts. There is also a Studio function for generating a summary, study aid, quiz, timeline, infographic, or presentation.

Main features of NotebookLM

Analysis and information retrieval

NotebookLM automatically creates brief summaries of uploaded materials. The tool lets you search for facts and answer questions based on document content, with each answer linked to a specific location in the source file. The service produces structured answers and helps organize notes by topic and project.

Audio podcast generation

Audio Overview is a unique feature that creates a podcast in the form of a conversation between two AI hosts discussing the uploaded materials. This capability has no direct equivalent among other tools.

Studio and document work

The Studio feature allows generating various content formats: summaries, study aids, quizzes, timelines, infographics, presentations, and tables. The tool supports importing data from Google Docs and Sheets, as well as real-time collaboration.

Advantages of NotebookLM

Verifiability and reliability

Unlike ChatGPT, which mixes user data with the model’s general knowledge, NotebookLM answers strictly based on the uploaded sources and always points to the specific location in the text. This provides greater reliability for professional document work and eliminates hallucinations.

Unique capabilities

Audio Overview — a feature for generating podcasts in a conversation format between two hosts — is unique and has no analogs. The tool also works directly with YouTube videos and audio files, supporting more than 20 formats.

Accessibility and integration

The basic plan is completely free and works without a VPN. The tool integrates with Google Workspace (Google Docs, Sheets), supports collaboration for teams and study groups, and has a clean, simple interface.

Disadvantages of NotebookLM

Functional limitations

NotebookLM is limited only to uploaded sources — it does not provide information from the internet. The limit of 50 sources per notebook may be small for large projects. The tool does not work with paywalled pages or protected PDFs.

Product status

NotebookLM is currently an experimental version, so there may be stability or usability limitations. The interface is available only in English, although sources and answers in Russian are supported.

Requirements and limitations

A Google account is required to use the tool. There may be a slight learning curve due to advanced features. Paid features are available only through Google subscriptions (not separately), and some payment methods may cause difficulties when paying.
