Built for vibe coders

Turn rough ideas into rigorous specs.

Spec-driven development keeps vibe coding grounded: intent first, shippable next. Describe what you want to build — no polish needed. Four AI personalities debate your idea, challenge each other's assumptions, and settle on an optimized spec you can actually ship from.

Explorer Clarifies intent & gaps
Architect Proposes structure
Critic Challenges & pushes back
Mediator Settles on the best path
