A Lightweight Environment with Fully Editable Text & Diagrams
Draft with AI, review instantly as diagrams, and edit in text or diagrams on a single canvas.
SysMLv2 Modeler combines the speed and simplicity of a lightweight, file-based tool with powerful, fully editable graphical modeling.
What Sets It Apart:
- The File Is the Model: Point any AI agent in VS Code straight at your .sysml files, fully integrated with GitHub version control.
- Two-Way Diagram Editing: Drag, connect, and add – your text file updates automatically in real time. Connecting complex relationships is far easier directly on diagrams.
