Built for designers

Design interactions. Not just screens.

Move beyond static mockups. Build working prototypes with real behavior — loading states, validation, transitions, and error handling.

Real working prototypes
Live preview URLs
No code required

Your designs show pixels.
Users experience behavior.

You design beautiful screens. But between your Figma file and the live product, something gets lost. Loading states disappear. Error pages never get built. Animations get simplified. The edge cases you cared about? They got cut for time.

Static mockups don't show behavior

Figma frames can't demonstrate loading states, form validation, transitions, or error handling. Stakeholders approve a design, then get surprised when the real thing behaves differently.

Handoff loses intent

You spend hours annotating designs with interaction notes, edge cases, and responsive rules. Developers interpret them differently, and you end up in revision loops trying to match your original vision.

Can't test edge cases

Empty states, error messages, loading spinners, permission denied — these all get cut from mockups because they're too many screens. But users experience them all the time.

The 3Web fix

Describe the interaction you want. 3AI builds working code with real behavior — loading spinners that actually spin, forms that validate input, transitions that animate, error states that recover. No mockup can do that.

Describe the interaction.
Get working code.

No translating designs into developer specs. You describe what should happen — "fade in the cards one by one," "show a skeleton while loading," "shake the input on invalid email" — and 3AI builds it with real behavior.

  • Describe any interaction in plain English
  • 3AI builds with real animations and transitions
  • Every edge case handled — loading, error, empty
  • Responsive by default — test on any screen size

What designers prototype

Every interaction pattern — built from a description.

Onboarding flows

Multi-step signup, tooltips, progress indicators

Form interactions

Validation, error messages, success states, loading

Navigation patterns

Sidebars, tabs, breadcrumbs, modals, drawers

Data visualizations

Charts, tables, dashboards, filters, sorting

Permission levels

Admin vs member views, gated content, role-based UI

Empty and error states

Fallback UI, error recovery, 404 pages

Frequently Asked Questions

Figma prototypes are clickable mockups — they simulate navigation but can't show real behavior. 3AI builds actual working code with real form validation, API calls, loading states, and error handling. Users interact with real software, not a simulation.
No. You describe what you want in plain English — "show a loading spinner for 2 seconds, then fade in the content" — and 3AI implements it. You can iterate by describing changes.
Yes. Describe your design tokens (colors, spacing, typography) in the prompt and 3AI applies them consistently. You can also paste CSS or Tailwind config for precise matching.
The prototype IS the production code. Unlike throwaway mockups, what 3AI builds is a real web application that can be shipped directly or handed off to developers to extend.
