2. Google Gemini (Visual Understanding)
Developer Use Cases
Gemini's Visual Superpowers:
- UI mockup → HTML/CSS/React code (90%+ fidelity)
- Diagram interpretation (flowcharts → Mermaid/code)
- Screenshot debugging ("why does this look broken?")
- Design token extraction (colors, spacing from images)
Gemini 2.5 Pro for Development
Best-in-class for:
- Complex UI conversion: Upload Figma screenshot → Get Tailwind components
- Diagram comprehension: Architecture diagrams → Implementation plan
- Error analysis: Upload error screenshot → Get debugging steps
Model selection:
- Gemini 2.5 Pro: Complex visual reasoning, long context
- Gemini 2.5 Flash: Quick visual tasks, lower cost
Integration Workflow
Pattern: Visual → Code
┌─────────────────────────────────────────────────────────┐
│ 1. GEMINI 2.5 PRO │
│ Upload: screenshot.png of Figma design │
│ Prompt: "Convert this to a React component using │
│ Tailwind CSS. Use semantic HTML and │
│ include responsive breakpoints." │
│ │
│ → Output: JSX + Tailwind code │
└───────────────────────────┬─────────────────────────────┘

│ 2. CLAUDE CODE │
│ > claude │
│ "Refine this component for our Next.js project. │
│ Add proper TypeScript types, our Button component, │
│ and connect to the auth context." │
│ │
│ → Output: Production-ready component │
└─────────────────────────────────────────────────────────┘Pattern: Diagram → Implementation Plan
┌─────────────────────────────────────────────────────────┐
│ 1. GEMINI │
│ Upload: architecture-diagram.png │
│ Prompt: "Analyze this architecture diagram. │
│ Output a Mermaid diagram with the same │
│ structure, and list the components." │
│ │
│ → Output: Mermaid code + component list │
└───────────────────────────┬─────────────────────────────┘
↓ Paste mermaid to CLAUDE.md
┌─────────────────────────────────────────────────────────┐
│ 2. CLAUDE CODE │
│ "Implement the UserService component from the │
│ architecture in CLAUDE.md. Start with the │
│ interface, then the implementation." │
│ │
│ → Output: Implemented service │
└─────────────────────────────────────────────────────────┘Image Generation Alternatives
For generating diagrams, mockups, or visual assets:
| Tool | Best For | Format | Quality |
|---|---|---|---|
| Ideogram 3.0 | UI mockups, icons | PNG, SVG | High |
| Recraft v3 | Vectors, logos | SVG, PNG | Very high |
| Midjourney | Artistic visuals | PNG | Artistic |
| DALL-E 3 | Quick concepts | PNG | Good |
Workflow for generated images:
- Generate image with tool of choice
- Upload to Gemini for → code conversion
- Refine with Claude Code
