Codigram is a JavaFX-based visual modeling tool for creating UML Class Diagrams and Entity-Relationship Diagrams (ERD).

The application enables users to:

• Create diagrams manually through an intuitive drag-and-drop interface
• Generate diagrams using AI powered by Google Gemini
• Manage multiple diagrams within a single project
• Import/Export diagrams in JSON format
• Generate code from class diagrams (Java, CPP, C#, Python)
• Generate SQL DDL from ERD diagrams (MySQL, MSSQL, Sqlite3, Postgres)

• Interactive Diagram Editor: Create and edit UML classes and ERD entities with visual tools
• AI-Powered Generation: Use natural language prompts to generate complete diagrams via Gemini AI
• Code Generation: Automatically generate Java classes from UML diagrams with proper structure and relationships
• SQL DDL Export: Generate CREATE TABLE statements from ERD models
• Relationship Management: Define associations, inheritance, compositions, and cardinalities
• Visual Customization: Resize, move, and organize diagram components
• Project Management: Work with multiple diagrams in an organized workspace

• Language: Java
• Framework: JavaFX
• Build Tool: Maven
• AI Integration: Google Gemini API
• Version Control: Git & GitHub
