UML diagrams were meant to standardise system design, but they’ve become outdated — slow to build, hard to change, and rarely used in practice. Most tools feel clunky, and diagrams often go stale fast.

I’m building RapidChart, a tool to bring diagramming back to life — fast, flexible, and developer-first.

What makes it different:

Cursor-style interface for rapid diagram creation

Fully customisable and exportable

AI-assisted (works with GPT-4, Claude, etc.)

100% free

This began as part of my research at Imperial College London, and I’d really value your feedback.
