Generate UML diagrams from plain English. Describe your system, classes, or workflows and the AI creates proper UML notation in Mermaid and PlantUML — no syntax knowledge required.
UML (Unified Modeling Language) is a standardized visual modeling language used in software engineering to describe, visualize, and document the design of a software system. UML was created by Grady Booch, James Rumbaugh, and Ivar Jacobson and is maintained by the Object Management Group (OMG).
UML includes several diagram types: sequence diagrams for interactions over time, class diagrams for object-oriented structure, activity diagrams for workflows and business processes, state diagrams for state machines and lifecycle management, component diagrams for system architecture, and ER diagrams for database design.
Traditionally, creating UML diagrams requires either expensive desktop tools or learning diagram-as-code syntax. Cybewave Studio eliminates both barriers — describe your system in plain English and the AI generates proper architecture diagrams with correct UML notation using Mermaid and PlantUML rendering engines.
All standard UML diagram types, rendered with Mermaid and PlantUML via Kroki.
Model interactions between objects over time. Show method calls, returns, async messages, and alt/loop fragments. Essential for documenting API call chains and authentication flows.
Define classes, interfaces, attributes, methods, and relationships — inheritance, composition, aggregation. Perfect for object-oriented design and domain modeling.
Visualize system components, ports, interfaces, and dependencies between modules or services. Map deployment topology and service boundaries.
Model state machines with states, transitions, guards, and actions for workflows, protocols, and order lifecycle management.
Flowcharts for business processes with decision points, parallel forks, and swim lanes. Model CI/CD pipelines and approval workflows.
Entity-relationship models with fields, types, primary keys, foreign keys, and cardinality. Design database schemas visually before implementation.
Describe your system in natural language. The AI handles Mermaid and PlantUML syntax, UML notation, and layout automatically. Focus on design, not syntax.
Go from a paragraph of text to a complete UML diagram in seconds. No drag-and-drop, no shape palettes, no manual arrow routing.
Ask the assistant to add methods, change relationships, merge classes, fix errors, or explain any part of the diagram in plain English.
Download as PNG, SVG, or raw Mermaid/PlantUML code. Copy-paste into Notion, Confluence, GitHub READMEs, or any documentation tool.
Describe your system once and generate sequence diagrams, class diagrams, ER models, and component views simultaneously.
