Today's Tech Trivia

Answer at the end of this newsletter.

🚨White House Unveils New “Tech Corps”🚨

The White House has announced Tech Corps, a new Peace Corps–style program that sends U.S. technologists abroad to help partner nations deploy American AI tools.

What Tech Corps Will Do

• Recruit and train volunteers with STEM and engineering backgrounds.
• Deploy them to countries participating in the American AI Exports Program, where they’ll support “last‑mile” implementation of U.S. AI systems in agriculture, education, health, and economic development.
• Provide hands‑on technical help to governments and local organizations adopting American AI stacks.

Why It Matters

The program is part of a larger U.S. push to promote AI sovereignty, the idea that nations should adopt advanced AI while keeping control of their data and infrastructure.

The Bigger Picture

Tech Corps sits alongside new financing mechanisms, standards work, and partnerships announced at the summit.

Applications are now open at peacecorps.gov/tech. Volunteers will receive housing, healthcare, a living stipend, and a service award.

AI Prompt for Revising Presentation Slides:

I will paste my slide titles and bullets.

For each slide:

• Rewrite the title as a persuasive claim.
• Tighten bullets to be concise and concrete.
• Identify unclear or weak points.
• Suggest improved slide order.
• Recommend where a visual (chart, diagram, image) would improve clarity.
• Focus on clarity, persuasion, and flow.

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.

🆒Tell Me More

• NotebookLM slide decks are strongest when your sources already include a clear argument. If your sources are scattered, do a 5-line outline first, then generate.

• The most common “AI slide smell” is generic titles. Fix titles first and the whole deck improves.

• If a slide has more than one idea, split it. AI often merges concepts to be helpful, and that hurts the story.

• When a deck is “technically correct but forgettable,” add one concrete example per section.

⏩Quick Tips

• 🖼️ Image Swapping: Use the "Revise" prompt to specifically ask for a "minimalist icon" or "photorealistic image" to change the slide's vibe.

• 📊 Data Focus: If a slide is too wordy, prompt it to "convert this text into three clear bullet points."

• 📄 Source Tagging: Mention a specific filename in your revision prompt to force the AI to pull data from a particular document.

• 💾 PPTX Backup: Always export to PowerPoint before a meeting so you have a local copy that doesn't require an internet connection.

• 📝 Drafting First: Use the Chat feature to finalize your thoughts before clicking "Generate Slides" to get a better first draft.
