This intuitive approach makes it easy for anyone to bring their ideas to life without the need for advanced skills.
Multiple AI Models
The platform offers various AI models tailored to different artistic styles and generation speeds. Users can choose between the Standard model for quick anime-style character creation or opt for other models that provide varying levels of detail and artistic flair.

OnUml
AI Smart Chat
This is the star feature of OnUml. Instead of memorizing complex Mermaid syntax, you can describe your diagram needs in natural language. For example, you can type "Create a sequence diagram for a user login process with a database check" and the AI will generate the corresponding, syntactically correct Mermaid code for you. It acts as your intelligent design partner, translating your ideas into a structured diagram format instantly, which is perfect for brainstorming or quick documentation.
Live Diagram Rendering & Preview
As you type in the Mermaid editor or receive code from the AI chat, a live preview pane updates in real-time. This WYSIWYG (What You See Is What You Get) experience allows for immediate feedback. You can see exactly how your diagram will look as you build it, making it incredibly easy to spot errors, adjust layouts, and iterate on your design without any frustrating back-and-forth between coding and viewing.
Built-in Mermaid Editor with Smart Hints
For users who prefer direct control or want to fine-tune the AI's output, OnUml provides a clean, minimalist code editor dedicated to Mermaid syntax. It includes smart code hints and automatic syntax fixes to help you write valid code faster. This feature is ideal for learning Mermaid or for making precise adjustments to complex diagrams that require a developer's touch.
Diagram Export and Organization
Once your diagram is perfect, OnUml lets you export it in high-quality formats like PNG and SVG, making it simple to share in documentation, presentations, or reports. The platform also emphasizes ease of use with code saving and organization features, allowing you to keep your projects tidy and accessible for future edits, all without requiring any user registration.
