How to Use NotebookLM: Google’s AI-Powered Research Tool

Google’s NotebookLM is an AI-powered collaborator that helps you “do your best thinking” by analyzing your documents and notes. After uploading your files, NotebookLM effectively becomes an instant expert on those sources. You can then ask questions in a chat interface, and NotebookLM will answer with responses grounded in your content, complete with inline citations. This makes it a powerful tool for tech-savvy users who need to quickly synthesize and understand large or complex documents.

Updated September 2026: Google renamed NotebookLM to Gemini Notebook on July 16, 2026. It’s the same product — same notebooks, same sources, automatic redirects from old links — just a new name, a new blue-purple logo, and a new URL (notebook.google; the old notebooklm.google.com address still works). Since “NotebookLM” remains the name most people search for and the one used throughout this guide’s screenshots and steps, we’re keeping it here, with the new name noted wherever it matters. The tool itself has also moved on: it now runs on Gemini 3.5, syncs with the Gemini mobile app, and the Studio panel does a lot more than it used to — details below.

NotebookLM supports many input formats – you can upload Google Docs, Slides, PDFs, web URLs, text, or even YouTube videos as sources. Once your content is in place, you use the Chat panel to query the information. Each answer cites the exact passages from your sources, so you can verify the output. In addition to Q&A, NotebookLM can generate structured outputs from your content: for example, it can create summaries, timelines, FAQs, study guides, or an “Audio Overview” podcast of your material.

What’s changed since this guide was first written: the underlying model is now Gemini 3.5 (up from Gemini 2.0 Flash), the Studio panel has grown from five output types to eleven (Video Overview and Cinematic Video Overview joined Audio Overview and Mind Map, plus Reports, Flashcards, Quiz, Infographic, Slide Deck, and Data Table), and every notebook now includes a secure sandboxed “cloud computer” that can write and run code against your sources for data analysis. Pricing also changed: NotebookLM Plus was folded into the general Google AI subscription tiers (Plus/Pro/Ultra) rather than sold as its own add-on.

In this guide, we will walk through the key features of NotebookLM’s latest version: how to create a notebook and upload sources, how to interact via chat, and how to use the Studio panel to produce summaries, timelines, FAQs, and audio overviews. By the end, you’ll know how to leverage NotebookLM to make your research and note-taking faster and more effective.

What is NotebookLM?

NotebookLM is Google’s AI-powered note-taking and research assistant. It lets you upload your own documents (PDFs, Google Docs/Slides, web pages, text, even YouTube transcripts and audio) and then uses a Gemini-based model to analyze them. After you add sources, NotebookLM instantly “becomes an expert” on that material and can answer questions grounded in your documents, providing answers with inline citations back to the original text. In practice, NotebookLM can generate summaries, timelines, tables of contents, FAQs, study guides, briefing docs and more – all tailored to the content you provided. It even offers a conversational Audio Overview (a podcast-style summary) and a brand-new Mind Map feature to visualize key concepts. Your data stays private – Google does not use your uploaded content to train its models.

NotebookLM was first built for researchers and students, but any knowledge worker can benefit. It excels when you have multiple related sources or a large body of information to digest. For example, researchers can drop in academic papers and extract key findings, technical writers can feed in manuals or specs, product managers can aggregate market reports, and students can compile readings into a study guide. NotebookLM “is extremely useful” when you need to connect and synthesize scattered information from different files. By breaking complex materials into snippets and answers, it helps you uncover insights that would be hard to find by manual review.

Who Benefits and Use Cases

• Researchers & Students: Quickly summarize articles, extract quotes, create study guides or timelines. NotebookLM’s citation-backed answers make it ideal for literature reviews or exam prep.
• Product Managers/Analysts: Upload market research, specs, meeting notes, and get concise overviews or Q&A on key points. The NotebookLM Notebook Guide can generate briefing docs or FAQs from all your materials in one click.
• Technical Writers & Developers: Feed in design docs, code comments, or technical papers. NotebookLM can answer detailed questions (e.g. “What are the API requirements?”) with references to the exact section of your docs. It can also turn lengthy releases into bullet-point summaries.
• Educators & Teams: Assemble content for courses or projects. NotebookLM Business (Workspace version) lets organizations share notebooks and collaborate, with audit trails and analytics. For education, it can generate quizzes or glossaries from uploaded lecture notes or textbooks.
• Creative Projects: Even novelists or game designers are using it to organize world-building. NotebookLM can collate scattered notes (images, script drafts, reference URLs) into one interactive notebook and answer complex queries about characters or plot.

Getting Started: A Step-by-Step Guide

1. Sign in and create a notebook. Go to notebook.google (the old notebooklm.google.com address still redirects here) and sign in with your Google account (must be 18+ and in a supported region). You’ll see your dashboard listing any existing notebooks (or just a New Notebook tile). Click Create new.
2. Add your sources. After naming your notebook, use the Add Source panel to bring in material. You can upload files (PDF, TXT/Markdown, DOCX, PPTX, audio), link Google Drive (Docs or Slides), paste text directly, or provide a web or YouTube URL (it pulls the transcript). You can mix and match formats. Free notebooks support up to 50 sources; the paid Google AI tiers raise that ceiling to 100 (Plus), 300 (Pro), or 500–600 (Ultra).
3. Review the auto-generated summary. Once sources are added, the notebook immediately produces a summary and breakdown of your materials — topic headlines, key quotes, a basic overview — so you can see the big picture at a glance.
4. Ask questions and chat with your notebook. In the chat panel, type any question about your sources. Answers include inline citations that jump to the relevant sections of your documents, and you can ask follow-ups just like a conversational chatbot.
5. Create structured outputs. Use the Studio panel on the right for one-click generative tools grounded in your notebook’s content. As of 2026 this menu covers: Audio Overview (two AI hosts discuss your material, with a live “Join” mode to ask follow-ups by voice), Video Overview, Short Video Overview, Cinematic Video Overview, Mind Map, Reports, Flashcards, Quiz, Infographic, Slide Deck, and Data Table — a much longer list than the original FAQ/Timeline/Briefing Doc/Audio Overview/Mind Map set this guide covered when NotebookLM first launched Studio.
6. Run code against your sources. Every notebook now includes a secure, sandboxed “cloud computer” that can write and execute code for data analysis directly against your uploaded material — useful if your sources include spreadsheets or datasets and you want computed answers, not just summarized ones.
7. Take notes. In the Chat panel, responses have a Save to note icon. Click it to pin that answer or any text snippet into your notebook’s Notes area. You can also add your own notes manually, so each notebook becomes a living document.
8. Refine and iterate. You can add or remove sources anytime, and the notebook updates its understanding. Ask it to summarize the entire chat session into a final note to save your progress, and try different prompt styles — bullet lists, high-level summaries, more detail, or a specific tone.
9. Organize notebooks and sync to mobile. Create multiple notebooks for different projects. Since April 2026, notebooks also sync bidirectionally with the Gemini mobile app — a source you add on your phone via Gemini shows up in the notebook on desktop, and vice versa.

Tips & Best Practices

• Experiment with sources. Try uploading some recent or random documents to see what the tool can do. Even unrelated files can reveal hidden links.
• Mix content types. For richer insights, combine formats — PDFs, slides, and short clips together. The multimodal engine (Gemini 3.5) can parse embedded images in Docs/Slides.
• Use suggested prompts. After uploading sources, check the auto-generated summary for starter questions that can guide exploration before you think of your own.
• Iterate and expand. Add new sources gradually and regenerate outputs. Re-running a Mind Map or Video Overview as you refine topics often surfaces new connections.
• Vary output formats. Don’t stick to one view — with eleven Studio output types available, if a Report doesn’t cover a point, try a Quiz, Data Table, or Video Overview to reframe the content.
• Save important bits. If the AI gives a particularly useful answer, click Save to note right away, or ask it to “Summarize our chat” for a meta-summary you can resume from later.
• Share and collaborate. Sharing notebooks with teammates (full access or chat-only mode) and collaboration analytics are part of the paid Google AI tiers (Plus/Pro/Ultra) rather than the free tier.

Advanced Features

• Multilingual and Accessibility: Set a preferred language in Settings so outputs come back in that language; Audio Overviews support 50+ languages.
• Image & PDF Insights: Handles images embedded in PDFs and Slides — the AI can describe charts or diagrams and cite that text, not just plain paragraphs.
• Discover Sources: Describe a topic and it will auto-fetch relevant web articles into your notebook, a quick way to expand research scope without manual search.
• Video Overviews: Beyond the original Audio Overview podcast format, Studio can now generate a Video Overview, a shorter cut, or a Cinematic Video Overview (added April 2026) — a narrated visual walkthrough of your sources rather than just audio.
• Code execution: Each notebook includes a sandboxed environment that can write and run code against your sources, useful for computing over data rather than just summarizing it.
• Gemini app sync: Notebooks now sync bidirectionally with the Gemini mobile app, so sources and chats stay current whether you’re working from a notebook directly or from “Notebooks in Gemini” on your phone.
