## Why OpenPencil
<table>
<tr>
<td width="50%">
### 🎨 Prompt → Canvas
Describe any UI in natural language. Watch it appear on the infinite canvas in real-time with streaming animation. Modify existing designs by selecting elements and chatting.
</td>
<td width="50%">
### 🤖 Concurrent Agent Teams
The orchestrator decomposes complex pages into spatial sub-tasks. Multiple AI agents work on different sections simultaneously — hero, features, footer — all streaming in parallel with per-member canvas indicators.
</td>
</tr>
<tr>
<td width="50%">
### 🧠 Multi-Model Intelligence
Automatically adapts to each model's capabilities. Claude gets full prompts with thinking; GPT-4o/Gemini disable thinking; smaller models (MiniMax, Qwen, Llama) get simplified prompts for reliable output.
</td>
<td width="50%">
### 🔌 MCP Server
One-click install into Claude Code, Codex, OpenCode, Kiro, or Copilot CLIs. Design from your terminal — read, create, and modify `.op` files through any MCP-compatible agent.
</td>
</tr>
<tr>
<td width="50%">
### 🎨 Style Guides
Built-in style guide library with tag-based fuzzy matching. Apply visual styles (glassmorphism, brutalist, retro, etc.) to AI-generated designs. MCP tools for external agent access.
</td>
<td width="50%">
### 📦 Design-as-Code
`.op` files are JSON — human-readable, Git-friendly, diffable. Design variables generate CSS custom properties. Code export to React + Tailwind or HTML + CSS.
</td>
</tr>
<tr>
<td width="50%">
### 🖥️ Runs Everywhere
Web app + native desktop on macOS, Windows, and Linux — one Rust core, a single self-contained binary, no browser engine. `.op` file association — double-click to open.
