SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Converts user requirements into accurate Mermaid diagrams, reducing manual diagramming time and ensuring consistent visual representations.

Core Features & Use Cases

  • Supports multiple diagram types (flowchart, sequence, class, ER, Gantt, and more) and automatically generates both raw .mmd and preview-friendly .md files saved under figures/.
  • Performs Mermaid syntax validation and provides a rendered PNG for quick verification.
  • Useful for software design, data modeling, and project planning where diagrams are a common deliverable.

Quick Start

Provide a requirements description and request a Mermaid diagram; the tool will emit figures/<diagram-name>.mmd and figures/<diagram-name>.md with syntax-checked code.

What types of Mermaid diagrams can I create for software design and project planning?▼

For software design and project planning, you can create multiple Mermaid diagram types including flowchart, sequence, class, ER, and Gantt diagrams by describing your structural or temporal requirements.

How do I validate Mermaid syntax and preview the rendered output?▼

To validate Mermaid syntax and preview rendered output, the tool checks the generated code using Mermaid CLI and provides a rendered PNG image to confirm correctness before integration.

Do I need to manually write Markdown to display Mermaid diagrams in documentation?▼

You do not need to manually write Markdown to display Mermaid diagrams because the tool automatically generates a preview-friendly .md file saved under figures/ alongside the raw .mmd code.

What is the best way to convert data modeling requirements into ER diagrams?▼

The best way to convert data modeling requirements into ER diagrams is to input your entity relationships as text; the system selects the ER diagram type, generates the Mermaid code, and validates the syntax for visual representation.
