I Built an AI Architect for System Design — Here's How It Works

I wanted to change that. So I built SysDesAI — an AI-powered platform where you design systems step-by-step with an AI architect that guides you, challenges your decisions, and generates real architecture diagrams. The Problem When I was prepping for system design interviews, I noticed something: ByteByteGo has great videos, but you just watch — you don't practice Grokking has structured lessons, but the designs are pre-written — not yours System Design Primer is an amazing reference, but it's static text on GitHub ChatGPT/Claude can answer questions, but there's no structured workflow, no diagrams, no persistence None of these tools let you actually do system design the way you'd do it in an interview — describing requirements, making trade-offs, choosing between architectures, a
