One connected workspace
The decision, the model, and the conversation stay together.
Diagrams stay close
Embed editable C4 views beside the decisions they explain, without exporting stale screenshots.
Review stays precise
Discuss a paragraph, diagram, node, or relationship and resolve the thread where the work lives.
Architecture as code
Bring the model you already have.
Import Structurizr, C4 PlantUML, Mermaid C4, or structured JSON. Inspect normalized views, coverage, and source revisions without losing the original model.
- Live derived diagrams
- Revision-safe imports
- Source-to-view traceability
- Agent-ready MCP access
