Our take

Consider for portable text-defined diagrams

Document-based files connect editing with system previews.

Keep in mind: Syntax support depends on the bundled renderer. Release-version wording is ambiguous; test diagrams from other Mermaid tools.

What you can do

  • Edit .mmd sources
  • Inspect parse errors
  • Zoom preview
  • Export supported images

Good for

  • Documentation authors checking rendered output.

Consider alternatives for

  • People seeking unrestricted visual drawing.

Limitations & considerations

  • Captured minimum: iOS 14.0.
  • Syntax support depends on the bundled renderer. Release-version wording is ambiguous; test diagrams from other Mermaid tools.

Privacy & permissions

Diagrams and synced files may expose private architecture. Review storage destinations.
