The design-complete blueprint layer

The whole product, before you build it.

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.

What do you get with Koryvant?

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.

  • Every screen

    The complete surface of your app — not a hero and three placeholders. Each screen a user would reach is drawn.

  • Every state

    Empty, loading, populated, error, and edge cases per screen — the states real products live in, not just the happy path.

  • Light and dark

    Both themes, designed in lockstep with a shared token system, so the prototype reads the way a shipped product does.

  • A bespoke design language

    A spatial motif, a brand mark, and bespoke iconography derived for your idea — not a generic component-kit reskin.

  • Stack-agnostic handoff specs

    Voice, motion, and roadmap notes that hand off cleanly to any stack — so engineering starts from a decided design.

  • A safe static artifact

    The output is a clickable HTML prototype with bounded, predictable cost — nothing to run, nothing to break.

How does Koryvant work?

You describe an app in a chat, and Koryvant generates it, previews it, and lets you iterate for free — then unlock a project to open editing, deploying, and downloading.

  1. Describe

    Tell Koryvant what you want to build, in plain language, in a chat.

  2. Generate

    Koryvant generates a complete, non-generic clickable prototype from your prompt.

  3. Preview

    The prototype renders live in a sandboxed preview — free, no card, both themes.

  4. Iterate

    Refine it by chat and by direct edits until it matches what you had in mind.

  5. Unlock

    Unlock the project to open editing, deploying, and downloading.

  6. Deploy and download

    Publish it to a koryvant.com subdomain and download the full artifact set.

Who is Koryvant for?

Koryvant is for anyone who needs to see the whole product before building it — founders, product and design teams, and engineers.

  • Founders

    Show the whole product to a co-founder, a first user, or an investor before you commit engineering time.

  • Product and design teams

    Move from a written idea to a design-complete blueprint the whole team can click through in one sitting.

  • Engineers

    Start from a decided design surface with handoff specs, instead of designing while you build.

What is Koryvant not?

Koryvant is the design-complete blueprint layer, not a full-app builder. There is no backend, no database, and no running full-stack app.

It ships every screen, every state, both themes, a bespoke design language, and stack-agnostic handoff specs — as a safe static artifact with bounded, predictable cost. It is the design and UI layer your idea becomes before a line of app code is written, not a tool that runs a live full-stack application for you.

Frequently asked questions

What does Koryvant do?
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.
Is Koryvant free?
Generating, previewing, and iterating on a prototype is free — no card required. Unlocking a project to edit, deploy, and download is a one-time payment, with no subscription and no credits; see the pricing page for the current price.
Does Koryvant build a full app?
No. Koryvant is the design-complete blueprint layer, not a full-app builder — there is no backend, no database, and no running full-stack app. It ships the whole design surface as a safe static artifact.
What do I get when I unlock a project?
Unlocking a project lets you edit the prototype, deploy it to a koryvant.com subdomain, and download the artifact set. Iteration stays free and unlimited after unlock.
How is a Koryvant prototype different from a generic UI generation?
Koryvant derives a bespoke design language for your idea and draws every screen in every state across both themes — the whole product surface, not a single polished screen.
