Export diagrams - Convert .monopic and .monojson files to plain text or JSON
List diagrams - Find all Monodraw files in a directory
Open in Monodraw - Launch files directly in the Monodraw app
Create ASCII art - Generate boxes, flowcharts, tables, trees, and sequence diagrams
Diagram prompts - Pre-built templates for common diagram types
