I Built an AI System Design Coach — Clone It, Try It, Break It

The problem I kept running into

Every time I practiced system design, I'd hit the same wall: I'd sketch out a rough idea for "design WhatsApp" or "build a URL shortener," and then... nothing. No feedback. No indication if my choice of Kafka over RabbitMQ was justified or just cargo-culting. No one to ask "hey, what's your latency requirement?"

Real interviews have a human who prods you with the right questions. Solo practice doesn't. I built Arcwise to fix that.

What Arcwise does

Arcwise is an open-source, AI-powered system design coach. Drop in any problem, and it walks you through the full design process — just like a real interview session.
