AI Diagram Maker — Create Diagrams from Plain Language
Describe what you want — "draw a user registration flow" or "visualize the sequences between microservices" — and AI picks the best diagram language (Mermaid / PlantUML / D2 / Graphviz, etc.), generates the code, and renders it instantly. Refine iteratively with natural language via the AI editing assistant.
Create diagrams without writing code
Traditional diagram tools (Mermaid / PlantUML / D2) are powerful but require learning syntax. This tool lets AI understand what you want to draw and automates notation selection, syntax, and code generation.
Example: type "member registration → email verification → login flow" and AI generates the correct Mermaid `flowchart` nodes and arrows. The rendered result appears in the preview.
AI auto-selects the notation
AI picks the best notation for the purpose:
· Business flows / process diagrams → Mermaid (flowchart) · System-to-system interactions → Mermaid (sequenceDiagram) or PlantUML · Database structure → Mermaid (erDiagram) or ERD · Software architecture → Structurizr (C4) or D2 · Bar/pie charts → Vega-Lite · ASCII-art style → Ditaa · Math / logic circuits → TikZ / WaveDrom
Refine with the AI editing assistant
After the initial generation, request changes in natural language: · "Make the arrows red" · "Add 3 nodes" · "Simplify it"
Version history (v1=original / v2=AI output / v3+=edits) with diff view shows what changed at a glance. Roll back to any previous version in one click.
Code editing + preview
After AI generation, you're switched to the Code edit + preview tab automatically. Open the accordion to edit the AI-generated code directly.
