Illustrated Slides with Nano Banana

Create presentations where each slide is a complete AI-generated image with all text and content embedded directly in the image. No separate text layers — the presentation file is simply a container for full-page illustrated slides. Supports multiple visual styles from corporate to creative.

Key Principle

All content is embedded in the images.

Unlike traditional presentations with text overlays, this skill generates complete slide images where titles, bullet points, diagrams, and illustrations are all part of the generated image itself - like pages in a children's picture book.

Behavior

When this skill is triggered:

1. Get Presentation Topic

Ask the user for their presentation topic if not specified.

2. Ask for Visual Style

Always ask the user to choose a style:

🎨 What visual style would you like?

1️⃣ **Kawaii / Children's Book**
   Warm pastels, cream background, cute characters with faces
   Best for: Kids content, educational, playful topics

2️⃣ **Professional / Corporate**  
   Clean blues & grays, white background, modern icons
   Best for: Business, finance, tech presentations

3️⃣ **Bold / Creative**
   Vibrant colors, dynamic compositions, artistic flair
   Best for: Marketing, startups, creative pitches

4️⃣ **Minimalist / Elegant**
   Black & white with one accent, lots of whitespace
   Best for: Luxury brands, design, architecture

5️⃣ **Custom**
   Describe your own style preference

Which style would you like? (1-5)

3. Plan Slide Structure

Based on topic, plan ~8-12 slides:

• Title slide
• Introduction/Chapter slides
• Content slides (with embedded text & illustrations)
• Diagram/flow slides
• Summary/statistics slides
• Closing slide

4. Estimate Budget & Request Approval

• Each image: 0.1 USDC
• Recommend 1.5x buffer
• Tell user: "To create this presentation with X slides, I need a budget of Y USDC."

5. Generate Slide Images

For each slide:

1. Get x402 payment signature
2. Generate image with ALL content embedded (title, text, illustrations)
3. Download and save image
4. Repeat for all slides

6. Assemble Presentation

• Create PPTX with one full-page image per slide
• Optionally export as PDF
• Open for user review

const fs = require('fs');
const path = require('path');

async function buildImagePresentation(slidesDir, outputPath) {
    const pptx = new pptxgen();
    pptx.layout = 'LAYOUT_16x9';
    
    // Get slide images in order (01-*.png, 02-*.png, etc.)
    const slides = fs.readdirSync(slidesDir)
        .filter(f => f.endsWith('.png') && f.match(/^\d{2}-/))
        .sort();
    
    for (const file of slides) {
        const slide = pptx.addSlide();
        slide.addImage({
            path: path.join(slidesDir, file),
            x: 0, y: 0,
            w: '100%', h: '100%',
            sizing: { type: 'contain', w: '100%', h: '100%' }
