Hey Product Hunt! π
I'm SenYu, maker of OnUml β excited to launch here! β¨
OnUml is an AI-powered online tool to create Mermaid UML diagrams fast, without the usual friction.
Ever get stuck on Mermaid syntax or tired of starting diagrams from zero? I built OnUml to fix that!
Key Highlights:
π€ AI Chat-to-Diagram: Just describe the UML diagram you need in plain English, and let AI generate the Mermaid code!
π οΈ AI Syntax Fixer: Got broken Mermaid code? Let AI try to automatically find and fix common errors for you.
β‘ Live Preview: See your diagram update instantly as you type.
π« No Signup Needed: Jump right in and start creating. Seriously, no login required!
ποΈ Local Save & Folders: Your work stays in your browser, organized how you like it.
It's built for developers, designers, or anyone who needs to visualize systems quickly using Mermaid.
I built this to scratch my own itch and hope it's helpful for you too! It's still early days, so your feedback would be amazing. π
Give it a spin and let me know what you think!
