System-design interviews are a drawing exercise graded like an essay, and most people practice for them by reading. Draw the System makes you draw: it pairs interview scenarios with an embedded Excalidraw canvas so you rehearse the actual motion of the interview — boxes, arrows, trade-offs, out loud.
It's MIT-licensed and free. A companion cloud version adds a bring-your-own-server setup for AI-graded practice sessions.
