About this video

​ ​ 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.

Tom and I talked about: (00:00) Watch 6 AI agents design an app together (03:09) Demo: Designing a travel app with an AI agent swarm (08:20) Redesigning screens in different styles on the fly (13:20) The Pencil extension that turns Cursor into a design tool (15:07) One prompt to go from visual design to React website (19:00) Using design systems to keep your AI output consistent (22:02) From side project to 100K users in 8 weeks (27:44) Why vibe coding reminds Tom of the Flash era (30:05) Humanizing AI with cursors, craft, and personality
