What it does
Practice System Design Interviews by Actually Designing Systems Stop memorizing diagrams. Start building real architectures. Describe a system, watch it appear, ask "what if?" and iterate like a real interview. No drag-and-drop. No blank canvas paralysis. Just design.
Free AI system design tool. Describe your architecture in plain English and get instant diagrams. Create AWS, microservices, and cloud architecture diagrams in seconds. Perfect for system design interview prep.
Describe your system in plain English. Get an architecture diagram in seconds, plus a complete design doc your AI agents can actually build from. Change one, the other updates itself. No drag-and-drop. No blank canvas. Just describe what you need. Used by engineers for prototyping, by students for learning, and by candidates prepping for system design interviews. You have a system in your head, but getting it on paper takes longer than it should. You need a tool that builds with you, not just talks at you. Skip the drag-and-drop. Describe what you're building and get a complete architecture diagram, with all the components and connections, in seconds. Component details, data flows,…from infrasketch.net

VoiceDraw – Talk system design out loud, the diagrams draw themselvesJun 2026 · voicedraw.com · ▲49I was frustated by having to draw system design diagrams by hand when discussing it with my team mates or in an interview. So I thought "Wouldn't it be great if someone draws it for me, while I think out loud?". That is when I came up with VoiceDraw. You can just think out loud or discuss your system architecture with a friend/interviewer, the diagrams are automatically drawn along with your reasoning, open questions and tradeoffs beautifully written on to the side.

LeetSys2025 · leetsys.dev · ▲7I built a free platform for practicing system design interviews!: https://leetsys.dev. The currently available problems will always be listed as free! It lets you chat with an interviewer in real time as you work through a system design problem. It also gives you detailed feedback at the end of the interview that you can use to assess your performance and see where you can improve. Please try it out and let me know what you think!

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
