Document flows with Mermaid diagram pins

Render architecture and process diagrams as live Mermaid pins—update the diagram text without redrawing in a design tool.

Architecture sketches in slides go stale fast. Mermaid pins store diagram code on the canvas—flowcharts, sequences, and decision trees that re-render when you edit the source text.

Why Mermaid on the canvas?

Versioned in plain text

Diff diagram changes like code.

Always beside context

Place diagrams next to JSON, tables, or Markdown they describe.

Fast iteration

Ask AI to propose Mermaid, then pin the result.

Getting started

Create a Mermaid pin. Paste or generate diagram syntax. Use simple graphs first; split huge systems into multiple pins.

Frequently Asked Questions (FAQ)

Which diagram types work?

Flowcharts, sequences, and class diagrams—start with graph TD or flowchart LR.

Can non-devs edit?

Yes—edit labels in the text; preview updates live.

Export for slides?

Screenshot or link to the shared pin instead of redrawing.
