Tool
Koryvant
Chat prompt → full clickable prototype (all screens/states/themes)

About
Koryvant turns a chat prompt into a complete, non-generic clickable prototype — every screen, every state, light and dark, with a bespoke design language and stack-agnostic handoff specs. Preview it live, then refine it by chat.
You get the whole design surface of your product, generated from one prompt — every screen, every state, both themes, a bespoke design language, and stack-agnostic handoff specs.
The complete surface of your app — not a hero and three placeholders. Each screen a user would reach is drawn.
Empty, loading, populated, error, and edge cases per screen — the states real products live in, not just the happy path.
