The problem
Early product decisions move at the speed of turning an idea into screens. That usually means a spec, rough sketches, a prototype and a review, each in a different tool.
What we built
Plain-language input goes to multiple models through the Vercel AI SDK and comes back as wireframes and prototypes rendered on a canvas. Heavier runs execute in E2B sandboxes.
State lives in Supabase, Upstash and Vercel KV, and Stripe handles paid plans, so it runs as a service rather than a demo.
