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:
StyleDescription
whiteboard
Hand-drawn sketch on white. Black ink, orange accents.
corporate
Navy/white/gold. Clean sans-serif. Professional.
minimalist
Pure white, electric blue accent. Maximum negative space.
dark-tech
Near-black background, neon green. Terminal aesthetic.
playful
Bright pastels, rounded shapes. Modern startup vibe.
editorial
Black/white with red spot color. Magazine aesthetic.
Default: 
whiteboard
. User can specify any preset or describe a custom style.

Step 3: Generate

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