Describe the idea and its core flow
The prototype's purpose and the one flow it must demonstrate become the spine of the generated prompt — everything else is scoping around it.
AI PROTOTYPE PROMPT
Prototype Generation Prompt Builder
Assemble a focused prompt for generating a disposable, interactive product prototype with an AI coding tool — scoped tightly enough to get something clickable back fast.

Complete every field. The result updates only when you choose Calculate.
How it works
Set scope boundaries
Screen count, platform, data realism, and an explicit exclusion list are assembled into scoping clauses that keep the AI from over-building.
Get an assembled, ready-to-use prompt
The tool concatenates your inputs into a structured prompt scored for focus, not a generic template — paste it directly into your AI coding tool.

Frequently asked questions
Is the output prompt generic or built from my inputs?
It's assembled line by line from what you enter — the core flow, screen count, platform, visual style, and exclusions are all reflected directly in the generated text, not filled into a fixed template.
Why does the tool push me to exclude things?
AI coding tools tend to over-build a prototype into a half-finished app. An explicit out-of-scope list is the single biggest lever for keeping the result fast, disposable, and focused on one flow.
Which AI coding tools does the prompt work with?
It's written to be tool-agnostic — paste it into v0, Claude, Cursor, Bolt, or any AI coding assistant capable of generating a small interactive UI.
Should the prototype be treated as reusable code?
No — it's intentionally scoped as disposable. Once the flow is validated, rebuild the real thing with proper architecture rather than hardening the prototype.
How many screens should I request?
Keep it to only what the core flow touches. Requesting more than 6–8 screens for a single flow usually produces a shallower, less functional result per screen.
How We Compare
| Feature | MVPHub | v0 by Vercel | Bolt.new |
|---|---|---|---|
| Structures the prompt from your specific flow and scope | Included | Limited | Limited |
| Scores prompt focus before you generate anything | Included | Not included | Not included |
| Tool-agnostic output you can paste anywhere | Included | Not included | Not included |
| Free to use | Included | Not included | Not included |
v0 and Bolt.new generate the prototype itself once you give them a prompt, but neither helps you scope that prompt first. MVPHub builds and scores the prompt so the generation step — wherever you run it — starts from a tightly focused brief instead of an open-ended idea.
