How to write a good prompt for a prototype
When you generate a prototype from a prompt, the prompt is the brief. A vague prompt yields a generic result; a specific one yields a prototype that looks and behaves like the product you actually mean. Learning to write a good prompt is the highest-leverage skill in prompt-to-prototype design.

Name the product and its users
Start by saying what the product is and who it is for. "A scheduling app for physiotherapy clinics" produces a sharper result than "a booking app," because the users and their needs shape every screen.
The clearer the audience, the less generic the output. A tool designed for clinic staff looks different from one designed for consumers, and naming that difference up front pays off across the whole prototype.
Describe the core flows and screens
Name the few things a user most needs to do — the core flows — and let the tool derive the supporting screens around them. You do not have to list every screen; you do have to be clear about what the product is for.
Being specific about the core loop is what keeps the result on target. The settings and edge screens can be derived, but the heart of the product should be stated.
Set the tone, then refine
Give a sense of the tone and any constraints — the brand feel, the platform, any must-haves — so the design language fits. Then treat the first result as a draft, not a final answer.
Koryvant is built for this loop: describe the product, preview the complete prototype, and refine it by chat until it is right, rather than trying to specify everything perfectly in one prompt.
Try it on your own idea
Describe your product to Koryvant and get a complete clickable prototype — every screen, every state, both themes — free to generate and preview.
Questions
- What makes a good prototype prompt?
- One that names the product and its users, describes the core flows, and sets the tone. Specificity about who it is for and what it does is what produces a non-generic result.
- Do I have to list every screen in the prompt?
- No. Name the core flows and let the tool derive the supporting screens. Koryvant works out the complete screen inventory from a clear description of the product.
- What if the first result is not quite right?
- That is expected. Koryvant is built to refine by chat, so you start from a clear brief and iterate rather than trying to specify everything in one prompt.
