What it does.

Mermaid Viewer is an online diagram editor that allows users to create and edit Mermaid diagrams directly in their browsers. The tool features live previews, eliminating the need for a 'Render' button, and users can visualize diagram changes instantly as they type. Mermaid Viewer also provides AI-Assisted Coding with a 'Generate with GPT-4' feature that converts text descriptions into Mermaid code. Users can export their diagrams in a variety of formats including SVG, PNG, and Markdown, with options for custom DPI and dark or light themes. Mermaid Viewer supports enterprise integration and offers features such as Docker private deployment and role-based access control. The tool also includes a smart debugging feature with syntax error highlighting and auto-correction suggestions. For collaboration, Mermaid Viewer supports real-time co-editing of diagrams through shareable editor links. It comes with recommended templates that allow users to quickly start diagramming. Data in Mermaid Viewer stays in the browser and is not stored on an external server, ensuring user data privacy.
