Help with Diagram Studio for macOS.

Start a library

On the welcome screen, choose or create a folder for your diagrams. Diagram Studio includes subfolders and remembers the selection with a security-scoped bookmark.

A preview reports an error

Check the source syntax and use the format hint in the optional agent companion. PlantUML may require network access to the configured render service. Direct builds can instead use a local PlantUML installation.

Recover a diagram

Open Library, choose Trash, select the item and click Restore. Permanent destruction is a separate confirmed action. For prior edits, select a live diagram and choose Versions.

Agent companion

The optional companion is installed separately. Run diagramstudio mcp-config for MCP configuration or open http://127.0.0.1:7423/openapi.json after starting the authenticated local API.
