Edit Slides in NotebookLM: No More Starting Over

Edit Slides in NotebookLM: No More Starting Over

Google has finally added the ability to edit individual slides within NotebookLM using simple text prompts. This update also introduces a long-requested PowerPoint export option for professional workflows.

Have you ever spent twenty minutes waiting for an AI to generate the "perfect" slide deck, only to realize that slide seven has a glaring typo or an image that looks nothing like your brand? 

Until now, NotebookLM users faced a frustrating "all or nothing" choice: keep the flawed deck or roll the dice on a full regeneration. 

Here's a Cool Tip: Edit Slides in NotebookLM.

Google has quietly upgraded its research powerhouse with a surgical editing tool that allows you to fix individual slides without touching the rest of your presentation. 

It is the bridge between AI creativity and human precision that business professionals have been waiting for.

Feature Explanation

The new "Revise" feature in NotebookLM is a prompt-based editing system. 

Instead of manually dragging text boxes or resizing images, you tell the AI what to change on a specific slide. 

You might ask it to "make the bullet points more concise" or "replace the chart description with a summary of the regional sales data."

This works through a "Pending Changes" system. 

You can go through your deck, mark up multiple slides with different instructions, and then process them all at once. 

Alongside this, Google added a native PowerPoint (.pptx) export. 

This allows you to take your AI-generated research and move it into the standard corporate presentation environment, though it currently prioritizes visual fidelity over text editability in the export.

What You’ll Gain

• Surgical Precision: Fix specific errors or tone issues on a single slide without losing the layout of others.
• Time Savings: Update your deck in seconds rather than waiting for a full 20-slide regeneration.
• Workflow Integration: Export directly to PowerPoint to combine AI insights with your existing company templates.

Step-by-Step Instructions

Here's how to do it.

Web and Desktop

1. Navigate to notebooklm.google.com.
2. Select the notebook containing your sources and navigate to the Studio tab.
3. Click on the generated slide deck you wish to modify.
4. Look for the pencil icon labeled "Revise" on the individual slide you want to change.
5. Type your specific instructions in the box. 
6. If you have more edits, move to other slides and repeat the process. They will appear in the Pending Changes list.
7. Click Generate new deck to apply all pending revisions simultaneously.
8. Click the three-dot menu in the corner and select Download PowerPoint (.pptx) to save it to your local drive.

iOS and Android

1. Open the Gemini or Google app and navigate to your NotebookLM dashboard, notebooklm.google.com.
2. Tap on your presentation to view it in full screen.
3. Tap the screen to reveal the overlay and select the Revise (pencil) icon.
4. Enter your change request. 
5. Tap Update Slide to see the refreshed version.

Pros and Cons

Pro: 

• Maintains consistency across the rest of the deck while fixing isolated issues.
• PowerPoint export makes it easier to share with colleagues who don't use AI tools.

Con: 

• You still cannot manually click and type into a text box; all changes must be via prompts.
• PowerPoint exports often render slides as images, making final text tweaks in PPT difficult.

Feature Access

The Slide Revision feature is currently rolling out to all users. 

Score

Total: 24/30 👍 Good

A vital update that moves NotebookLM from a "neat experiment" to a legitimate productivity tool for professionals.

Key Takeaways

This update gives users much-needed control over AI-generated content. 

By allowing slide-specific revisions and PowerPoint exports, Google is making it easier to move from raw research to a finished professional product.

Here's a Cool Tip:  Use DuckDuckGo's AI Tool.

DuckDuckGo's new Duck.ai image editing feature lets you enhance, modify, and transform photos using AI while maintaining the privacy-first principles the company is known for.

Instead of installing software or subscribing to expensive creative tools, you can edit images directly in your browser using simple prompts like “remove the background,” “improve lighting,” or “turn this into a watercolor painting.”
