NotebookLM Mind Map and Presentation Generation Tutorial: Quickly Visualize Your Notes (Now Gemini Notebook)

"Can NotebookLM create presentations?"

Yes! And not just presentations—it can also generate mind maps.

First, one thing to get out of the way: Google officially renamed NotebookLM to "Gemini Notebook" on July 16, 2026 (official announcement). Same tool, same features, same free tier — only the name changed. This article still says "NotebookLM" because that's what most people search for; if the interface says "Gemini Notebook," you're in the right place.

These two features are NotebookLM's most underrated treasures. Many people only know about its Podcast feature but don't realize it can also help turn documents into visual mind maps and professional presentations.

This tutorial will show you how to use them and how to get better results.

NotebookLM Visualization Features Overview

NotebookLM provides three visualization content generation features:

Importance of Visualization for Learning and Work

Research shows human brains process visual information 60,000 times faster than text.

This means:

• Mind maps help you understand complex concepts faster
• Presentations make your reports more persuasive
• Visual content is easier to remember

Efficiency Difference vs Manual Creation

Of course, AI-generated content may need subsequent adjustments, but at least the initial draft time is significantly reduced.

Mind Map Feature Tutorial

Mind maps are an excellent tool for organizing thoughts, and NotebookLM can automatically generate them for you.

What is NotebookLM Mind Map

NotebookLM's mind map feature automatically analyzes your uploaded documents, extracts core concepts and their relationships, then generates a visual mind map.

Differences from Traditional Mind Map Tools:

NotebookLM's advantage is speed—you don't need to conceive the structure from scratch, AI organizes it for you. The downside is lower adjustment flexibility.

How to Generate Mind Maps

Step 1: Prepare Sources

First, ensure your notebook already has uploaded source documents. For source upload tutorial, see NotebookLM Complete Tutorial.

Best Source Types for Mind Maps:

• Documents with clear chapter structure
• Reports containing multiple topics
• Course materials or textbooks
• Meeting notes (multiple agenda items)

Step 2: Click Generate

1. Find the "Studio" panel on the right side of the notebook
2. Click "Mind map"
3. Wait 10-30 seconds
4. Mind map generation complete

Step 3: View Results

The generated mind map displays in a center-outward radiating form:

• Center node: Document topic
• First layer: Main concepts
• Second layer: Secondary concepts
• Outer layers: Detailed content

Editing and Adjusting

Expand/Collapse Nodes:

Click the +/- button next to nodes to expand or collapse that branch, making it easy to focus on specific parts.

Feature Limitation Notes:

Currently NotebookLM's mind map editing features are limited:

• ❌ Cannot add custom nodes
• ❌ Cannot delete specific nodes
• ❌ Cannot adjust node positions
• ❌ Cannot modify connection relationships
• ✅ Can expand/collapse nodes
• ✅ Can zoom view

If you need major modifications, it's recommended to use the mind map as reference and redraw in professional tools (like XMind).

Comparison with Other Tools

How do NotebookLM's visualization features compare to other AI tools?

Summary: NotebookLM's advantages are "source-based" and "free," disadvantage is design aesthetics. Recommended workflow is to generate drafts with NotebookLM, then beautify with other tools.

FAQ

Q: Can presentations be downloaded directly as PPT?

Cannot download directly. But you can first export to Google Slides, then download as .pptx format from Google Slides.

Q: Can mind maps have custom nodes added?

Currently no. NotebookLM's mind maps are read-only, can only expand/collapse, cannot custom edit. If modifications needed, recommend screenshot and recreate in other tools.

Q: Can generated presentations use custom templates?

Not within NotebookLM. But after exporting to Google Slides, you can apply any Google Slides template.

Q: What's the maximum number of presentation pages?

Usually 8-15 pages, depending on source content length. Currently cannot specify page count.

Q: What to do when generation fails?

Possible reasons:

• Source content too little or too short
• Source format has problems
• Temporary system issues

Suggestion: Confirm source content is at least 1,000 words, format is correct, then retry.
