Hey everyone 👋
After working at big companies like Barclays and also freelancing, I kept running into the same issue: technical diagrams are essential, but they’re either outdated, missing, or painful to create and maintain.
So I decided to do something about it.
This tool was born out of that frustration and is now a research project I'm building with Imperial College London. It lets you generate clean, beautiful technical diagrams (UML, ERDs, architecture, and more) from plain English — in seconds.
Here’s what makes it special:
Natural language input – just describe what you need, and it appears.
Instant results – stop wasting hours dragging boxes and lines.
Completely free – no paywalls, no limitations. Built for the dev community.
Customisable output – tweak and edit the diagrams to fit your needs.
Would love to hear what you think, and what features you'd like to see next.
