About Mermaid Architect: AI-Native Diagram Companion
🚀 The Ultimate Mermaid Workspace for ChatGPT & Gemini (v2.0.1)
Mermaid Architect is a professional-grade workspace that provides tailored visual tools for your preferred AI。Whether you need a quick preview or a full-scale architectural editor, we bridge the gap between AI logic and technical design。
✨ Platform-Specific Optimization
🤖 For Gemini (Full Feature Suite): Since Gemini lacks native rendering, we provide both an Inline Preview (quick toggle) and the Pro Sidebar workspace for a complete, end-to-end visual workflow。
⚡ For ChatGPT (Native Enhancement): We integrate elegantly with ChatGPT's new renderer, focusing on the Pro Sidebar to provide professional editing and parallel workflows without UI clutter。
🛠️ Core Capabilities
🖥️ Pro Sidebar (Push Layout): On both platforms, our sidebar intelligently resizes the chat interface to create a dedicated, side-by-side IDE experience。
🔍 Precision Snap-Capture: Features advanced Regex purification to extract clean, valid Mermaid syntax from any AI response instantly。
🌐 Arc Browser Compatible: Full sidebar support for browsers without native Side Panel API, ensuring a consistent experience everywhere。
🎨 Blueprint Aesthetics: Transform generic AI output into stunning, presentation-ready blueprints with professional-grade style presets。
🔒 Privacy & Performance
100% Local Rendering: Your data never leaves your browser; all processing is strictly client-side。
Zero Friction: No accounts, no tracking—just a fast, secure professional workflow。
High-Res Export: Download as SVG or high-resolution PNG (2x/3x) for your official documentation。
