FAQPage Schema
How do I turn wireframes into interactive HTML prototypes?▼

To turn wireframes into interactive HTML prototypes, you provide a design brief describing desired interactions and navigation. The prototype generation renders functional HTML, CSS, and JS components with working states ready for clickable testing.

Can I generate live prototypes for mobile app screens and SaaS dashboards?▼

Yes, you can generate live prototypes for mobile app screens and SaaS dashboards. Prototype generation covers landing pages, mobile interfaces, and design systems to validate end-to-end user flows.

What is the best way to create shareable demos for user testing?▼

The best way to create shareable demos for user testing is generating interactive HTML experiences. These clickable prototypes provide working navigation and states, enabling live reviews, stakeholder feedback, and developer handoff.

Does prototype generation work with existing design systems?▼

Yes, prototype generation works with design systems by translating your design briefs into interactive HTML experiences. It renders functional components, navigation, and states that align with your established UI/UX patterns.

What do I need to provide to build a clickable prototype from a napkin sketch?▼

To build a clickable prototype from a napkin sketch, you need to provide a prototype brief describing your desired interactions. The tool then outputs a functional HTML prototype with working navigation ready for testing.

Why use interactive HTML for prototype validation instead of static wireframes?▼

Use interactive HTML for prototype validation to demonstrate user flows end-to-end with working navigation and states. Static wireframes lack clickable interactions, whereas HTML prototypes accelerate stakeholder feedback and reduce rework.
