The prototype that gets thrown away
Most prototypes are sketches — a few key screens, the happy path, enough to nod along to in a meeting. They are useful for a moment and then discarded, because when the real build begins there is nothing in them precise enough to build against. The engineer starts over, and the prototype's decisions are quietly relitigated one by one.
That throwaway quality is not a law of nature; it is a consequence of prototypes being incomplete. A sketch of three screens cannot be handed off, because a build needs the other twenty — and every state each of them can be in. The gap between looks-about-right and buildable is exactly the gap that gets filled, expensively, later.
Design-complete, not a mood board
Koryvant is being built to produce a prototype that is design-complete: every screen, every state — empty, loading, error, full — in both light and dark, carrying a bespoke design language rather than a stock theme borrowed from a thousand other apps. The aim is a prototype thorough enough that there is little left to guess.
Completeness is what changes a prototype from a picture into a specification. When the awkward states are already designed and both themes already resolved, the decisions that usually get improvised mid-build are made up front, deliberately, where they are visible and cheap to change. A mood board suggests; a design-complete prototype decides.
Handoff to any stack
Because it is a design surface, Koryvant does not lock you into how it was made. The idea is stack-agnostic handoff — the prototype plus specs a team can build against in React, in Flutter, in whatever they already use — so the design travels and the engineering choice stays open.
That said, the honest framing: Koryvant is in active build-stage. The frontend and backend exist; the AI generation engine that produces these prototypes is the next stage of the work. The design-complete handoff described here is what it is being built to deliver — a direction stated plainly, not a finished product dressed up as one.
