Key insights
- A static mockup can't show what happens on tap — clicks dead-end, so reviewers are left guessing at the intended behavior.
- Interactive prototypes make intent legible: they demonstrate the state changes, transitions, and feedback that a flat image can only hint at.
- Iterate in plain language — describe the change ("switch to a light theme", "add entrance animations") instead of hand-editing every layer.
- Scope each edit to a selection: pick one element, prompt a targeted change, and leave the rest of the screen untouched.
- Treat motion as part of the spec — entrance animations and transitions belong in the prototype, not a footnote in the hand-off.
- One artifact serves every role — designers explore more options faster, PMs turn a spec into a prototype in minutes, founders sell the vision, no code required.
Do / Don't
- Do: Prototype the interactions and transitions, not just the static screens, so intent is visible.
- Do: Iterate with short, plain-language prompts scoped to the element you're changing.
- Do: Bake state changes and entrance animations into the prototype itself.
- Don't: Ship flat mockups where every tap dead-ends and the behavior is left to guesswork.
- Don't: Rely on a still image to communicate motion or state changes — it can only imply them.
