How it works
We calculate readiness against your goal
Each validation goal needs a different share of interactive screens — testing task completion needs far more clickable screens than testing concept understanding. Your readiness score reflects that.
Get a scoped prototype outline
The result breaks down interactive vs static screens and flags where your current plan under- or over-builds for what you are actually trying to learn.

Frequently asked questions
Does Prototype Sprint generate the actual clickable prototype for me?
No. Prototype Sprint assembles a scope outline and computes a readiness score from the structured fields you enter — it does not build, design, or export a real interactive prototype, and it does not run a real AI/LLM generation step.
Why does the required interactive-screen share depend on my validation goal?
Testing whether users understand a concept can often be done with a mostly static walkthrough, but testing whether users can complete a core task requires most of that flow to be genuinely clickable. The score adjusts its bar per goal instead of using one fixed threshold.
What counts as an "interactive" screen versus a static one?
Interactive means a user can click, tap, or type on it and see a state change — even a simple prototyping-tool link-through counts. Static means it is shown for context only, with no working interaction.
My build-effort score is high — should I cut screens?
Usually yes. A prototype scoped purely for validation rarely needs more than the core flow and one or two supporting screens; anything outside that adds build time without adding validation value.
How is this different from Design Cut?
Design Cut scores whether your full MVP design scope (screens, components, animations, interactions) is right-sized for a first release. Prototype Sprint scores one narrower thing: whether the interactivity in your prototype matches what your specific validation goal requires.
How We Compare
| Feature | MVPHub | Figma | Whimsical |
|---|---|---|---|
| Validation-goal-based readiness score | Included | Not included | Not included |

| Actually build the clickable prototype | Not included | Included | Included |
| Visual design and prototyping canvas | Not included | Included | Included |
Figma and Whimsical are where the clickable prototype actually gets built and linked together. Prototype Sprint runs before that — a scope check confirming which screens need real interactivity for your specific validation goal before you spend time wiring links.
