Deck Generator

Generate complete presentations where every slide is an AI-generated image in a consistent visual style.

Quick Start

1. Read the content spec (user provides slide content or a markdown file)
2. Read references/styles.md to pick or customize a visual style
3. Run scripts/generate-deck.py with content + style

Workflow

Step 1: Content Spec

Accept slide content in any format. Normalize to this structure per slide:

• Title: Bold headline
• Body: Key points, stats, or narrative
• Visual cues: Icons, diagrams, layouts described in words

If user provides a markdown file with --- separators, parse each section as a slide. If user provides a topic only, generate 10-14 slides following standard deck structures.

Step 2: Style Selection

Available style presets:

Default: whiteboard. User can specify any preset or describe a custom style.

Step 3: Generate

# Set your API key
export GEMINI_API_KEY="your-gemini-api-key"

# Run the generator
python3 scripts/generate-deck.py \
  --content slides.json \
  --style whiteboard \
  --title "Deck Title" \
  [--output-dir ./output] \
  [--aspect 16:9]

The script:

1. Generates each slide image via Imagen 4.0 API
2. Saves all images to the output directory
3. Optionally creates a Google Slides presentation (requires Google Slides API credentials)
4. Returns paths to all generated images

Step 4: Review & Iterate

To regenerate individual slides:

python3 scripts/generate-deck.py \
  --content slides.json \
  --style whiteboard \
  --slides 3,7 \
  --output-dir ./output

Key Details

• Cost: ~4 cents per image. A 14-slide deck costs roughly 56 cents in API calls.
• Speed: ~2 minutes for 14 slides.
• API: Imagen 4.0 via Google's Generative Language API
• Auth: Set $GEMINI_API_KEY environment variable
• Aspect ratios: 16:9 (default), 1:1, 4:3, 3:4, 9:16
• Image models: imagen-4.0-generate-001 (best quality), imagen-4.0-fast-generate-001 (faster)
