From prompt to editorial diagram in one step.

Tell your AI agent what you need. Diagram Design picks the right type and renders a self-contained HTML diagram that matches your brand.

Describe it

Name the diagram you need — architecture, flowchart, sequence, pyramid — and the skill picks the closest visual type.

Matched to your brand

The skill reads your website and applies your paper, ink, accent and fonts in about 60 seconds.

Export anywhere

One self-contained HTML file with no build step, no JavaScript and no external dependencies. Redraw draw.io or Mermaid sources too.

Why Diagram Design

Editorial quality, without the 30-minute color-picking sessions.

One accent color, 1px hairline borders, no shadows, max 10px radius, and a strict 4px grid. Diagrams that look hand-tuned, not AI-generated.

Everything you can draw with Diagram Design.

Twenty-eight visual types, three static variants each, and import from draw.io or Mermaid.

28 visual types

Architecture, flowchart, sequence, state machine, ER, timeline, swimlane, quadrant, tree, org chart, venn, layers, pyramid, radar, loop and more.

Brand matching

Reads your website and applies your paper, ink, accent and fonts in about 60 seconds.

Three static variants

Minimal light, minimal dark and full-editorial for every type. No build step required.

draw.io & Mermaid import

Redraw existing .drawio or Mermaid sources at your chosen format, size and detail level.

Accessible by default

Screen readers announce title and description; prefers-reduced-motion shows the complete static frame.

Editorial design system

One accent color, 1px hairlines, no shadows, 4px grid. Coral-tinted focal nodes draw the eye to what matters.
