I Watched 6 AI Agents Design an App In Real Time And It Blew My Mind | Tom Krcha

Tom is the CEO of Pencil, one of the coolest AI design tools that I’ve ever tried. Watching 6 AI agents design a beautiful app in real-time will genuinely blow your mind. Tom showed me how it all works under the hood (a simple JSON file?!) and how you can use Pencil to design right where you code in Cursor, Claude Code, and more.
