Renamed · 2026-07-16
Google renamed NotebookLM to Gemini Notebook on 16 July 2026. The product itself continues — Google's announcement says it "remains a standalone product" — and the domain moved from notebooklm.google to notebook.google with a permanent redirect. The enterprise edition is now Gemini Notebook Enterprise.
NotebookLM
NotebookLM is Google's AI research assistant powered by Gemini that lets you upload documents, PDFs, and videos to chat with your sources and generate AI-powered podcast-style Audio Overviews.
NotebookLM is Google's AI-powered research and note-taking assistant, built on the Gemini large language model and released to the public in 2023. Unlike general-purpose AI chatbots, NotebookLM is specifically designed to work exclusively with the sources you provide—it reads, synthesizes, and answers questions grounded entirely in your uploaded materials, dramatically reducing the risk of AI hallucination.
The core workflow is simple yet powerful: upload your sources—PDFs, Google Docs, Google Slides, web URLs, YouTube videos, audio files, or pasted text—and NotebookLM creates a personalized AI assistant for that specific collection. You can ask questions about any topic covered in your materials, request summaries of individual documents or the entire notebook, identify connections across sources, and generate structured study guides or briefing documents. Every response comes with citations that link directly back to the exact passage in your source material.
One of NotebookLM's most celebrated features is Audio Overview, which transforms your uploaded sources into an engaging, conversational AI-generated podcast. Two synthetic AI hosts discuss and debate the key ideas from your materials in a natural back-and-forth dialogue, making it an exceptional tool for auditory learners or anyone who wants to absorb information while commuting, exercising, or multitasking. Audio Overviews can be customized with instructions to focus on specific angles or audiences.
NotebookLM is particularly well-suited for students and researchers who need to process large volumes of academic literature, legal professionals reviewing contracts and case files, journalists researching stories, writers building knowledge bases for long-form projects, and business professionals conducting competitive analysis or market research. The tool excels at cross-document synthesis—finding patterns, contradictions, and connections that would take hours to identify manually.
The platform is free to use with a Google account, and NotebookLM Plus offers expanded limits and enterprise features for teams and organizations. Because all answers are grounded in your specific sources, NotebookLM is trusted in professional and academic settings where accuracy and citation traceability are paramount.

Frequently Asked Questions
Is NotebookLM free to use?
Yes, NotebookLM is free to use with a Google account. The free tier allows you to create notebooks, upload multiple sources, chat with your documents, and generate Audio Overviews. NotebookLM Plus is available for users who need higher source limits, more notebooks, and enterprise-grade privacy controls, making it suitable for professional teams and organizations.
How does NotebookLM avoid AI hallucination?
NotebookLM is specifically designed to answer only based on the sources you upload. It does not draw on its general training data to fill in gaps or speculate beyond your materials. Every response includes citations that point directly to the exact passage in your uploaded document, allowing you to verify the information instantly. This source-grounded approach makes it far more reliable than general-purpose AI chatbots for research and analysis tasks.
What file types can I upload to NotebookLM?
NotebookLM supports a wide variety of source formats including PDFs, Google Docs, Google Slides, web page URLs, YouTube video links, audio files, and pasted text. This broad compatibility means you can build research notebooks from almost any type of content — academic papers, reports, lecture recordings, podcast episodes, articles, and more — all in one place.
What is the Audio Overview feature and how does it work?
Audio Overview is a distinctive feature that converts your uploaded sources into an AI-generated podcast. Two synthetic AI voices engage in a natural, conversational back-and-forth about the key ideas in your materials, similar to a deep-dive podcast episode. You can customize the overview with specific instructions — for example, to focus on a particular theme or explain concepts to a beginner audience. It is especially popular with students and professionals who prefer auditory learning.
Who should use NotebookLM?
NotebookLM is ideal for students and researchers managing large volumes of academic literature, legal professionals analyzing contracts, journalists building research dossiers, writers organizing sources for long-form projects, and business teams conducting market research or competitive analysis. Anyone who needs to deeply understand, synthesize, and query a specific collection of documents will benefit enormously from NotebookLM's source-grounded approach.
