Transform messy sketches into clean architecture with our class diagram generator AI

Skip the tedious setup and focus on system architecture

Experience AI-powered diagramming that understands your workflow

Generate professional UML class diagrams in seconds
Creating UML class diagrams with Miro's AI is refreshingly simple. Open Create with AI, select "Diagramming" from the menu, then choose "UML Class Diagram" to generate your system architecture visualization. Whether you're designing a new microservice, documenting an existing API, or planning a database schema, our AI understands the nuances of object-oriented design and creates diagrams that follow UML best practices.

Design microservice architectures faster
When you're architecting microservices, every bounded context needs clear entity relationships. Instead of spending hours manually mapping out service boundaries, describe your domain model to our UML class diagram AI generator. "Create a class diagram for an e-commerce order service with Order, OrderItem, Customer, and Payment entities, showing aggregation and composition relationships." Watch as the AI generates a clean diagram showing proper associations, multiplicities, and dependencies – giving you a solid foundation for service design discussions.

Document API structures with precision
API documentation becomes exponentially clearer when backed by visual class structures. Describe your REST API's resource models, and let the AI create comprehensive class diagrams showing inheritance patterns, interface implementations, and data transfer objects. Your development team gets immediate visual context for complex object hierarchies, reducing integration confusion and speeding up development cycles.

Validate database schemas before implementation
Before committing to database designs, visualize entity relationships through UML class diagrams. Our AI helps you spot potential design issues early – like missing foreign key relationships or overly complex inheritance patterns that might cause performance problems. Generate diagrams for your proposed schema, iterate on the design with your team, and ensure everyone understands the data model before development begins.

Plan system integrations visually
When integrating with third-party systems or legacy applications, clear interface definitions prevent costly miscommunication. Describe the integration points, shared data models, and boundary objects to our AI. The generated UML class diagrams become the single source of truth for integration contracts, helping both internal teams and external partners understand exactly what data flows where.

Streamline code review processes
Transform abstract architectural discussions into concrete visual reviews. Generate class diagrams for proposed code changes, new feature implementations, or refactoring initiatives. Development teams can quickly grasp the impact of architectural decisions, spot potential coupling issues, and provide more targeted feedback during design reviews.

UML Class Diagram AI Generator FAQs

Can I customize the generated UML class diagrams?
Absolutely! Every AI-generated diagram is fully editable. You can modify classes, add attributes and methods, adjust relationships, change styling, and extend the diagram with additional UML elements from Miro's comprehensive shape library.
How can my team collaborate on UML class diagrams?
Miro supports real-time collaboration where multiple architects and developers can simultaneously edit diagrams, add comments, and provide feedback. Use @mentions to notify specific team members about architectural decisions or questions.
Do I need UML expertise to use the class diagram generator?
While basic UML knowledge helps, our AI generates standard-compliant diagrams from natural language descriptions. The tool includes helpful tooltips and guidance for UML notation and best practices.
What's included in the Free plan for UML class diagram generation?
The Free plan includes 10 AI credits per team per month. Each UML class diagram generation consumes one credit, allowing you to create up to 10 AI-generated diagrams monthly.
How do AI credits work for UML class diagram generation?
Each use of the class diagram generator consumes one AI credit regardless of diagram complexity. Starter plans include 25 credits per license monthly, Business plans include 50 credits, and Enterprise plans include 100 credits per license.
