What is Mermaid Architect
Mermaid Architect is a diagram workspace for people who generate Mermaid in chat. It auto-detects Mermaid blocks in ChatGPT and Gemini responses and previews them in a side panel that pushes the chat aside into an IDE-like layout. Because Gemini has no native rendering, it offers both an inline preview toggle and the full sidebar workspace, while on ChatGPT it integrates with the existing renderer and focuses on the sidebar for editing and parallel work. Precision snap-capture uses regex purification to pull clean, valid Mermaid syntax out of a response, blueprint styling turns raw output into presentation-ready diagrams, and results can be exported as SVG or high-resolution PNG. Rendering is entirely client-side with no accounts and no tracking, and Arc Browser is supported through a fallback for browsers lacking the Side Panel API.
