Work from your own sources
Upload PDFs, websites, YouTube videos, audio files, Google Docs, Google Slides, lecture recordings, and other source material so NotebookLM can summarize them and connect related ideas.
Google NotebookLM
Google NotebookLM is an AI research tool that helps people summarize their own sources, ask grounded questions, and turn material into cited answers or Audio Overviews. It is positioned for study, research, brainstorming, and presentation prep.
What NotebookLM is
Google NotebookLM is an AI research tool and thinking partner built around the information you choose to upload. Instead of answering from general web knowledge, it works from your PDFs, websites, videos, audio files, Google Docs, Google Slides, and other source material, then summarizes that content and points you back to the evidence.
Its core purpose is to help users understand complex material faster and with more confidence. The site positions NotebookLM for study, presentation prep, brainstorming, and research workflows, and it emphasizes citations, source-grounded answers, and Audio Overviews for listening to source content in a different format.
The product is built with Gemini models and is available through NotebookLM as well as paid plan tiers on the plans page. The page also notes that organizations and schools can keep their data private and that individual data is not used for training unless feedback is shared.
Core capabilities
Source citations and quote tracing
NotebookLM cites its responses with exact quotes from the uploaded material, so you can verify where an answer came from instead of relying on a generic response.
Gemini-based source understanding
The product uses Gemini models to understand source material more deeply, which supports summarization and cross-document connections.
Audio Overview output
Create an Audio Overview that turns your material into a podcast-style “Deep Dive” discussion for listening while commuting or reviewing content on the go.
Multi-purpose knowledge workflows
Use the same source base for study help, presentation outlines, brainstorming, reports, flashcards, and quick answers across research and work workflows.
Tiered plan access
The plans page indicates different usage tiers, including higher limits, early or priority access, and increased source caps for paid plans.
Practical ways to use NotebookLM
Studying and exam prep
Upload lecture recordings, textbook chapters, and research papers, then ask NotebookLM to explain difficult concepts in simpler language and reinforce understanding with examples.
Research synthesis and ideation
Drop in meeting notes, brainstorming documents, market research, or competitor research, then use NotebookLM to identify themes and surface new ideas for a project.
Presentation planning
Collect source material for a talk or pitch and ask NotebookLM to turn it into a presentation outline with supporting evidence and key talking points.
Customer support knowledge bases
Add help center articles, product documentation, and release notes, then use NotebookLM to draft quick answers to common customer questions. The plans page says public notebooks are available for consumer accounts.
Training and onboarding
Upload manuals, class recordings, or internal onboarding material and use Audio Overviews or source-grounded summaries to help people learn the material faster.

FAQ
What makes NotebookLM different from other AI note-taking tools?
NotebookLM is source-grounded: you upload your own materials, and its answers reference those sources with citations and quotes. That makes it better suited to research and study workflows than a general-purpose note app that answers from broad model knowledge.
How does Gemini improve NotebookLM?
The source text says NotebookLM is built with the latest Gemini models, which helps it understand uploaded materials more deeply, summarize them, and identify connections across documents. The page does not spell out specific model versions or all effects of the integration.
Can NotebookLM turn source material into audio?
Yes. NotebookLM can generate an Audio Overview described on the page as a “Deep Dive” discussion from your sources, and the plans page also mentions Audio & Video Overviews and other artifacts. The page does not specify all supported output formats on the public homepage.
How does NotebookLM handle privacy and sharing?
The source text says organizations and schools can keep their data private and that individual data is not used for training unless feedback is shared. The page also says you can create a public notebook for consumer accounts.
What kinds of work is NotebookLM best suited for?
NotebookLM supports source-based research, study, presentation prep, brainstorming, and content synthesis. The homepage and plans page show it can work with materials like PDFs, websites, YouTube videos, audio files, Google Docs, Google Slides, lecture recordings, research papers, competitor research, and support articles.
