System Context Diagram

What a good system context diagram shows

A context diagram shows exactly one system in the middle, the people who use it, and the external systems it integrates with — and nothing else. Its power is scope: it's the artifact where a room that thinks it agrees discovers where it doesn't.

How Architext builds it

Describe the system to the AI co-editor or import your infrastructure, then keep the context view as the top level of the model — Architext's leveled containers mean the same model drills from context to containers to components.

Document, export, and share

Once the diagram is right, compile the full solution-architecture document, generate an audience-tailored slide deck, export to PNG, SVG, Mermaid, or PowerPoint, or share a read-only link — all from the same model.

FAQ

What goes in a context diagram?

The system (one box), its user roles, and the external systems it touches. Internals belong one level down.

Is this the C4 Level 1 diagram?

Yes — context is C4's first level; Architext's containers give you the drill-down to container and component views from the same model.

Can I generate it from infrastructure?

Import your IaC to seed the model, then group internals into a system container — the top level becomes your context view.
