OnUml

OnUML is a lightweight, browser-based diagramming tool focused on Mermaid.js, enhanced with AI-assisted chat input. Designed for developers, technical writers, and software architects, it simplifies the creation of UML diagrams and flowcharts through natural language prompts and real-time rendering. Key features include AI-Assisted Mermaid Generation, Live Diagram Rendering, Built-in Mermaid Editor, Automatic Syntax Fixes, Code Saving and Organization. I highly recommend this tool for creating UML diagrams, especially for the real-time UML preview feature.
