Koryvant vs ProtoPie
ProtoPie is a tool for crafting rich, high-fidelity interactions without code. Koryvant generates the whole product from a prompt — every screen a user reaches, in every state, across both themes — as a clickable prototype.
How they differ
ProtoPie is a prototyping tool known for building detailed, sensor-rich interactions and micro-interactions without code, one prototype at a time.
Koryvant generates the complete product surface rather than a single crafted interaction: the whole screen inventory in every state, in both themes, under a bespoke design language, plus stack-agnostic handoff specs. It is the whole decided design, handed off, not a deep dive on one interaction.
Koryvant is the design-complete blueprint layer, not a full-app builder. There is no backend, no database, and no running full-stack app.
Where Koryvant is different
Koryvant is built to hand you a design-complete blueprint of the whole product, priced once per project.
The complete screen inventory
Every screen a user would reach is drawn — not a hero and a handful of placeholders. You see the whole product surface, not a single showcase view.
Every state, not just the happy path
Empty, loading, populated, error, and edge cases per screen — the states a real product actually lives in, so the blueprint holds up under review.
Light and dark, in lockstep
Both themes designed together on a shared token system, so the prototype reads the way a shipped product does rather than a single-theme mockup.
A bespoke design language
A spatial motif, a brand mark, and iconography derived for your idea — not a generic component-kit reskin that looks like everything else.
Stack-agnostic handoff specs
Voice, motion, and roadmap notes that hand off cleanly to any stack, so engineering starts from a decided design instead of designing while it builds.
One-time, per project

Questions
- Is Koryvant a ProtoPie alternative?
- For generating the whole product as a clickable prototype from a prompt rather than crafting individual interactions, yes — every screen and state, both themes, with handoff specs.
- Does Koryvant capture motion and interaction detail?
- Its handoff specs include voice and motion notes alongside the clickable prototype, so interaction intent carries into the build on any stack.
- Does Koryvant lock me into one framework?
- No. The handoff specs are stack-agnostic, so engineering can build on any framework it prefers rather than starting from a decision baked into generated code.
- How does pricing compare?
- Koryvant is free to generate, preview, and iterate. Unlocking a project to edit, deploy, and download is a one-time payment per project — no subscription and no credits. See the pricing page for the current price.
