NotebookLM Is Now Gemini Notebook: 5 New Features You Need to Try Today

What Changed in the Gemini Notebook Rebrand

Google's November 2026 rebrand of NotebookLM to Gemini Notebook is far more than a marketing makeover. What began as an experimental Google Labs playground is now deeply integrated into the core Google Workspace ecosystem.

By migrating the underlying intelligence to Gemini 4 Carbon, the tool now handles up to 50 source documents simultaneously—including 4K video lectures, raw audio podcasts, GitHub repositories, and 1,000-page scientific PDFs—with zero loss of needle-in-a-haystack citation accuracy.

5 Landmark Features in Gemini Notebook

Here are the five standout capabilities you should explore immediately:

1. Customizable Audio Overviews (Studio Controls): You can now guide the viral AI podcast hosts! Choose between a 5-minute executive briefing, an entertaining debate, or a deep academic breakdown with custom tone prompts.
2. Native YouTube & Video Ingestion: Paste any YouTube URL or upload raw MP4 footage. Gemini Notebook analyzes the visuals, spoken dialogue, and on-screen text simultaneously without requiring manual transcript exports.
3. Interactive Citation Mind Maps: Click on any claim in your generated notes to see an interactive 3D visual graph linking the exact paragraph, timestamp, or PDF page where the fact originated.
4. Multi-Source Gemini 4 Carbon Synthesis: Ask complex cross-document questions like 'Compare the pricing strategies across these 12 competitor PDFs' and receive structured comparison tables in seconds.
5. One-Click Slides & Docs Export: Automatically convert your research notebook into a branded presentation deck or polished executive briefing with source footnotes preserved.

Step-by-Step: Turning 10 Research Papers into a Podcast

Here is the proven workflow to generate high-retention audio summaries from dense research:

1. Create a Notebook: Go to Gemini Notebook and start a new project.
2. Upload Your Sources: Drag and drop up to 50 PDFs, research papers, or web URLs.
3. Set the Focus Prompt: Before clicking Generate on the Audio Overview, enter your steering prompt: 'Focus on real-world creator applications, highlight cost differences, and keep technical jargon accessible.'
4. Download & Listen: In 90 seconds, your custom two-host podcast episode is ready to stream or download as an MP3 for commute listening.
