DESIGN SYSTEMS.
NOT diagrams.
Describe your backend architecture in plain English. AI generates interactive diagrams you can edit, stress-test, and export.

THE PIPELINE
FROM_INTENT_TO_DIAGRAM
Natural Input
Describe system logic in plain English. AI parses context, constraints, and architectural requirements.
Visual Logic
AI generates interactive diagrams. Visualize your architecture decisions and data flows on an infinite canvas.
Export & Integrate
Export diagrams as PNG, SVG, PDF, or Mermaid. Generate context files for Cursor, Claude Code, and Windsurf.
CORE MODULES
What you can use in the free public beta today
Interactive Canvas
Drag, drop, and connect architecture components on an infinite canvas with snap-to-grid precision.
Natural Language
Describe your system in plain English. AI generates the architecture diagram automatically.
Multi-Format Export
Export diagrams as SVG, PNG, PDF, or Mermaid for documentation and presentations.
IDE Context Export
Export architecture as agent skills for Cursor, Claude Code, and other AI IDEs.
Auto Layout
Automatically organize your architecture with sophisticated layout algorithms.
Chaos Mode
Simulate failures and stress test the resilience of your architecture design visually.
EVERYTHING INCLUDED
No credit card. No tiers. One free workspace while we iterate in the open.
