About OPM Studio
OPM Studio is a web-based diagramming tool built for Object-Process Methodology (OPM), a visual modeling language standardized in ISO 19450. It enables engineers, systems architects, and researchers to create clear, structured diagrams that capture both the structure and behavior of complex systems.

Key Features
- Interactive canvas with pan, zoom, and intuitive controls
- Full OPM notation support (objects, processes, states, links)
- Shareable diagrams via link
- Built-in tutorials to learn OPM fundamentals
- Works entirely in the browser with no installation required
