Image to UML Converter

This tool accepts an image of a diagram and outputs an editable UML model in PlantUML syntax along with a vector diagram export. It targets common diagram types such as class, sequence, and activity diagrams and is suitable for developers, architects, and instructors who need a reusable UML artifact from existing visuals.

Conceptually, the pipeline detects shapes, arrows, and groupings in the image, classifies elements by UML role (class, actor, lifeline, message), and infers relationships (associations, dependencies, messages). The detected elements are translated into PlantUML code and rendered into a scalable SVG for visualization. The system provides a confidence score for each element, enabling downstream review and refinement.

Unique value lies in converting static diagram images into editable, standards-based UML representations with export options suitable for version control, documentation pipelines, and integration with modeling workflows. Use cases include migrating legacy diagrams into modern UML models, documenting architectures from whiteboards or scans, and producing classroom-ready examples with executable PlantUML syntax. Core features include: file upload, diagram-type auto-detection, PlantUML text output, SVG diagram export, and optional accuracy controls. The approach emphasizes non-destructive drafts and iterative refinement, allowing teams to improve the model over multiple passes.
