Design used to be about rectangles on a canvas. Development was code in an IDE. The gap between them? Endless handoffs, mismatches, and wasted cycles. Were here to change that. We’re building an AI-native, code-based design tool that lets designers vibe design directly on real UI components - with an AI-native design engineer, on a canvas that thinks in code. With Jux, designers can: –Import and evolve Figma assets –Design with tokens, systems, and real code –Preview and publish live components –Collaborate with developers in a common language The result: UI that’s immediately production-ready. This is more than speeding up design. It’s a new foundation for product development - where AI helps automate the repetitive. Our belief is simple: Designers should focus on creation. Devs should receive real, working components. And AI should assist in between. Are you Juxed?
