If you've searched for NotebookLM lately and ended up on a page called Gemini Notebook, you're in the right place — Google renamed its AI research assistant on July 16, 2026. Same tool, new name, and honestly, a much better product than the one that launched three years ago. I spent time testing the current version so you don't have to learn it the hard way. Here's how to use Gemini Notebook in 2026, step by step, and what's actually worth your attention.
Wait — What Happened to NotebookLM?
Short version: Google folded everything into the Gemini brand. The old notebooklm.google.com address now redirects to notebook.google.com automatically, your notebooks moved over with it, and there's a mobile app for iOS and Android now. The rename wasn't just cosmetic, though. Google also upgraded the engine underneath it to the Gemini 3 family in mid-2026, added video features, study tools, and (for paid users) even the ability to write and run code inside your notebooks. If your last impression of this tool is "it summarizes PDFs," it's time for a second look.
What Gemini Notebook Actually Does Differently
The core idea hasn't changed, and it's still what makes this tool special: it answers from YOUR sources, not from the whole internet. Upload your documents, and the AI only reasons over that material, citing exactly where each claim came from. That means no hallucinated "facts" — well, far fewer of them — because every answer points back to a specific page in your own files.
This is the opposite of how ChatGPT works by default. ChatGPT is a generalist that knows a little about everything; Gemini Notebook is a specialist on your material. Studying for exams from your lecture slides, summarizing 40 research papers, building a product knowledge base for a small business, writing a literature review — that's the sweet spot. It accepts PDFs, Google Docs and Slides, websites, YouTube videos, audio files, and pasted text.
How to Use Gemini Notebook: The 5-Step Beginner Workflow
Step 1: Sign in and create a notebook
Go to notebook.google.com and sign in with your Google account. The free plan is genuinely free — no credit card, no trial period. Click "Create new" and give the notebook a real name, not "Untitled." You'll thank yourself later when you have twelve of them.
Step 2: Add your sources
Hit "Add sources." You can upload files from your computer, link Google Docs/Slides, paste URLs, or add YouTube videos. On the free plan you get up to 50 sources per notebook, each up to 500,000 words or 200MB — that's several textbooks per notebook, so most people never hit the ceiling. One tip: upload the actual materials you trust, not random web pages. The quality of your answers depends entirely on what you feed it.
Step 3: Ask questions like you mean it
Type a question in the chat. But here's what separates casual users from people who actually get value: ask multi-part questions that force the AI to connect sources. Not "what is photosynthesis?" but "compare how sources 3 and 7 explain photosynthesis, and tell me which one covers the light-dependent reactions better." Click the citations in the answer to jump straight to the source page. That's the feature that makes this trustworthy.
Step 4: Generate something with Studio
This is the fun part. The Studio panel turns your sources into outputs: Audio Overviews (a two-host podcast discussing your material), Video Overviews (narrated explainers), Flashcards and Quizzes, Mind Maps, Slide Decks, Infographics, and Deep Research reports. Pick one, give it a short instruction about tone or focus, and let it cook. An Audio Overview of your lecture notes turns a boring bus ride into a study session.
Step 5: Check the citations, then trust it
Seriously, click the citations the first few times. The tool is good, but your grade or your business decision is on the line — verify that the answers actually come from your sources. Once you've seen it cite correctly five times, you'll trust it for the small stuff.
The 2026 Features Worth Knowing About
There's a lot of new stuff this year. Here's what actually matters, in my view:
- Short Video Overviews. New in the September 2026 back-to-school update: 60-second animated explainers with spoken audio, supporting 80+ languages. Great for grasping a hard concept fast. Shareable, too.
- Audio recorder in the mobile app. Record a lecture on your phone and the transcription lands right alongside your uploaded files, ready to be cited and quizzed. This one's a quiet killer feature for students.
- Quizzes and flashcards with formats. Short answer, multiple choice, fill-in-the-blank — with explanations that cite back to your sources. It basically builds your exam prep for you.
- Discover Sources. You no longer have to bring everything yourself. Start a chat about your project and the tool suggests sources from the web to add, which is a big deal for research (it was introduced in the June 2026 update).
- Code execution (paid, rolling out). Every notebook now ships with a secure cloud computer. Upload survey data or a spreadsheet and ask it to analyze trends and draw charts — it writes and runs the code for you. As of now this is rolling out to AI Ultra subscribers first and coming to Pro users.
- Slide decks and data tables. Ask it to turn your research into an actual presentation or a structured table, then download and edit. Less "AI wrote a paragraph," more "AI did the tedious part of my job."

What It Costs in 2026
Good news: the free tier is enough for most people. You get 100 notebooks, 50 sources per notebook, document chat, plus audio and video overviews included. If you hit limits, the paid tiers fold into Google's AI subscriptions now: Plus at $4.99/month (200 notebooks, 100 sources per notebook, roughly double the usage), Pro at $19.99/month (500 notebooks, 300 sources, four times the usage), and Ultra from $99.99/month for power users. Cinematic Video Overviews need Pro or Ultra. Prices are a snapshot — Google has changed them before, so check the plans page before you pay.

My Honest Take
Here's my opinion after testing it: Gemini Notebook is the single best free study and research tool Google makes right now. Not because the AI is the smartest — ChatGPT and Claude will out-reason it on open-ended questions — but because of the citations. Knowing exactly where an answer came from changes the relationship from "do I trust this?" to "let me check the source." For students, researchers, and anyone drowning in documents, that's more valuable than raw model intelligence.
The flip side: don't use it as a replacement for reading. An Audio Overview gives you the shape of your material, not the depth. Use it to review and to find connections, then read the parts that matter. If you want to understand the bigger AI picture, our GPT-6 Astra explainer and our MCP explainer are good next reads.
