The new Gemini Notebook update (formerly NotebookLM) introduces three genuinely new capabilities you should care about: a secure cloud computer that writes and executes Python code inside each notebook, AI-powered source discovery that finds relevant web sources from a topic description, and new output formats including charts, PDFs, and spreadsheets. The rename from NotebookLM to Gemini Notebook happened on July 16, 2026, but the product remains a standalone research tool — same URLs, same notebooks, same free tier. The biggest practical change is that Gemini Notebook can now do complex data analysis grounded in your sources instead of just summarizing them.

What Is Gemini Notebook (Formerly NotebookLM)?
Gemini Notebook is Google's AI-powered research and learning tool that lets you upload sources — PDFs, websites, YouTube videos, Google Docs, audio files — and then ask questions, generate summaries, and create study materials grounded in those sources. It was originally introduced at Google I/O 2023 as "Project Tailwind" and launched as NotebookLM later that year. As of July 2026, more than 30 million people and over 600,000 organizations use it, according to Google's announcement.
The tool's core value proposition is grounded AI: every answer cites specific passages from your uploaded sources, so you can verify what the AI said against the original material. This makes it fundamentally different from a general-purpose chatbot that pulls from its training data.
What Actually Changed in the Gemini Notebook Update?
The rename: NotebookLM is now Gemini Notebook
On July 16, 2026, Google officially renamed NotebookLM to Gemini Notebook. The change aligns the product's brand with the Gemini model family that powers it — the tool had been running on Gemini 3 models since March 2026, making it the only major Google Labs product without "Gemini" in its name.
What did NOT change:
- All existing notebooks, shared links, and saved URLs continue to work (notebooklm.google redirects automatically)
- The product remains standalone — it is not being absorbed into the Gemini app
- The free tier is still free
- Audio Overviews, Video Overviews, Deep Research, Mind Maps, and all existing features work the same way
The old NotebookLM logo was updated with a blue-purple Gemini gradient (9to5Google).
Code execution: a secure cloud computer in every notebook
This is the single most significant new capability. Gemini Notebook now gives each notebook a secure cloud computer that can write and execute Python code natively. According to Google's announcement, this "allows Gemini Notebook to write and execute code natively, helping you conduct complex data analysis grounded in your sources."
What this means in practice: instead of just getting a text summary of your uploaded financial reports, Gemini Notebook can now write Python code to create pivot tables, run statistical analysis, generate charts, and produce structured data outputs — all grounded in the documents you uploaded.
The code execution capability first rolled out to Google AI Ultra and Workspace business customers in June 2026 as part of the "Gemini 3.5 and Antigravity" upgrade. The July 16 announcement committed to expanding it to all Google AI Pro users on the web in the coming weeks (TechCrunch).
Discover Sources: AI-powered source finding
"Discover Sources" lets you describe a research topic in plain language, and Gemini Notebook searches the web to find and summarize relevant sources. You then review what it found and add individual sources to your notebook with one click. This feature was announced by Google in April 2025 and has been rolling out to all users since then.
The key distinction: Discover Sources does NOT auto-generate a final answer. It populates your sources panel so you can then ask your own questions across the material. This preserves the tool's grounded-research philosophy — the AI finds sources, you decide what to do with them.
An "I'm Feeling Curious" button lets you explore random topics and see the source discovery agent in action.
As of August 7, 2026, Google also announced automatic source adding for Workspace users, further streamlining the workflow.
New output formats
Gemini Notebook's Studio panel can now generate a wider range of outputs from your sources:
| Output format | What it does | Availability |
|---|---|---|
| Slide Deck | Creates a polished presentation; downloadable as PDF or PPTX | All tiers (18+) |
| Infographic | Turns complex information into a single visual summary; downloadable as PNG | All tiers (18+) |
| Charts | Data visualizations generated from your sources via code execution | Pro and above |
| Spreadsheets | Structured data output created via code execution | Pro and above |
| Audio Overview | Turns sources into an engaging "Deep Dive" podcast-style discussion | All tiers |
| Video Overview | Visual + audio summary of sources | All tiers |
| Mind Map | Visual concept map showing relationships between topics | All tiers |
| Flashcards/Quizzes | Study materials generated from sources | All tiers |
| Briefing Doc | Structured document summarizing key points | All tiers |
| FAQ | Question-and-answer format from your sources | All tiers |
| Timeline | Chronological view of events from sources | All tiers |

The slide deck feature supports customization: you can choose between a "Detailed Deck" (full text, good for emailing) or "Presenter Slides" (visual, key talking points), select output language, set length (short/default/long), and provide a custom prompt to guide generation.
Cross-app syncing
Gemini Notebook now syncs across the Google ecosystem:
- Gemini app: Notebooks are accessible and editable inside the Gemini app (available since April 2026)
- Google Search AI Mode: Notebooks will appear in Search's AI Mode soon (no specific date given)
- Changes sync between the standalone site and the Gemini app in real time
This means a notebook you start on notebooklm.google.com is now accessible and editable inside the Gemini app — you no longer need to treat the two as separate tools.
How Much Does Gemini Notebook Cost?
Gemini Notebook is not sold as a standalone subscription. Access is bundled into Google's AI plans:
| Plan | Price | Notebooks | Sources per notebook | Daily chats | Deep Research | Audio overviews/day |
|---|---|---|---|---|---|---|
| Standard (free) | $0 | 100 | 50 | 50 | 10/month | 3 |

How to Use Gemini Notebook: 7 Beginner Tips
1. Start with the "Discover Sources" feature
Before manually uploading files, try the "Discover Sources" button in the Sources panel. Type a research topic like "AI adoption in healthcare 2026" and let Gemini Notebook find and summarize relevant web sources. You can add any of the results to your notebook with one click. This is the fastest way to build a source base from scratch.
2. Upload your own documents for grounded analysis
Gemini Notebook supports Google Docs, Google Slides, PDFs, text and markdown files, web URLs, copy-pasted text, public YouTube video URLs, and audio files. Each source can contain up to 500,000 words or up to 200MB for uploaded files (Google Workspace). The key advantage over a general chatbot: every answer cites the specific passage in your sources, so you can verify accuracy.
3. Use Audio Overviews to learn on the go
Audio Overview turns your sources into a podcast-style discussion with two AI hosts discussing the material. It takes one click in the Studio panel. This is one of the most popular features — free users get 3 per day, Pro users get 20. It's perfect for turning a dense research paper into something you can listen to during your commute.
4. Try code execution for data analysis
If you have a Pro or Ultra subscription, experiment with asking Gemini Notebook to analyze data from your sources. For example: "Create a pivot table showing revenue by quarter from this earnings report" or "Run a statistical summary of the survey data in these documents." The AI writes and executes Python code in a secure environment, then returns the results.
5. Generate a slide deck for presentations
The Slide Deck feature turns your sources into a polished presentation. Use the "Presenter Slides" format for a clean visual deck with key talking points, or "Detailed Deck" for a comprehensive deck good for emailing. You can download the result as PDF or PPTX. Tip: use the custom prompt field to guide the style — "Create a deck for beginners using a bold and playful style with a focus on step-by-step instructions."
6. Try Deep Research for multi-source synthesis
Deep Research is a separate feature from Discover Sources: it runs a multi-step planning-search-synthesize cycle that can browse hundreds of websites and produce a multi-page report. Free users get 10 Deep Research runs per month; Pro users get 20 per day. Deep Research counts are tracked separately from your daily chat quota (AI Weekly).
7. Sync with the Gemini app
If you use the Gemini app for daily work, your notebooks are now accessible there too. Start a notebook on the standalone site, then pull it up inside the Gemini app to ask follow-up questions or pull context into a broader conversation. Changes sync in real time.
What Stayed the Same (and What Might Confuse You)
The rename creates a naming puzzle. There are now three related surfaces:
- Gemini Notebook (the standalone product at notebooklm.google)
- Notebooks in the Gemini app (a project-management feature that syncs with Gemini Notebook)
- AI Mode in Google Search (notebooks coming soon)
All three share the word "Notebook" but are different surfaces. The standalone Gemini Notebook is the research tool with all the features described above. The "Notebooks" section in the Gemini app is for organizing chats and projects — it syncs with Gemini Notebook but has fewer features (9to5Google).
Features that did NOT change in the update:
- Audio Overviews (still one-click podcast-style summaries)
- Video Overviews (still visual + audio summaries)
- Deep Research (still multi-step web research)
- Mind Maps (still visual concept maps)
- Flashcards and quizzes (still available)
- The free tier (still free with the same limits)
- Source grounding and citations (still the core philosophy)
What This Means for You
For students and researchers: The code execution feature is the biggest upgrade — you can now ask Gemini Notebook to actually analyze data from your sources rather than just summarizing text. Pair it with Discover Sources to build a literature review base in minutes.
For business users: Slide Deck generation with PPTX export means you can turn a pile of research into a board presentation without leaving the tool. The automatic source adding for Workspace users (announced August 7, 2026) further reduces manual work.
For developers: The "secure cloud computer" concept is notable as a pattern — Google is embedding code execution into research tools, which signals where AI-powered development environments are heading.
