UI/UX
UI (User Interface) is how your app looks — colors, buttons, layouts, typography. UX (User Experience) is how your app feels to use — intuitive navigation, fast load times, clear feedback. For vibe coders, AI handles UI generation well but UX still requires human judgment about what makes a product pleasant to use.
Example
AI generates a beautiful signup form (great UI) with proper styling and layout. But it puts the form at the bottom of a long page, requires 12 fields, and shows no progress indicator (poor UX). The UI looks good; the experience frustrates users.
UI and UX are related but different. A beautiful app that's confusing to use has good UI but bad UX. A plain-looking app that's a joy to use has good UX but basic UI.
UI vs UX
| UI (User Interface) | UX (User Experience) |
|---|---|
| Visual design | Overall experience |
| Colors, fonts, icons | Flow, ease of use |
| How things look | How things work |
| AI generates well | Requires human judgment |
What AI Does Well (UI)
- Consistent visual styling
- Responsive layouts
- Component design with proper spacing
- Color schemes and typography
- Animations and transitions
What Needs Human Input (UX)
- Flow design — What order should steps happen in?
- Information hierarchy — What's most important on the page?
- Error handling — How do users recover from mistakes?
- Performance perception — Does the app feel fast?
- Accessibility — Can everyone use it?
Better AI Prompts for UI/UX
| Vague | Specific |
|---|---|
| "Make a dashboard" | "Create a dashboard with the most important metrics visible first, clear navigation, and loading states" |
| "Add a form" | "Create a multi-step form with progress indicator, inline validation, and clear error messages" |
The Quick UX Check
After AI generates a page, ask yourself:
- Can a new user figure this out in 5 seconds?
- Is the most important action obvious?
- What happens when things go wrong?
- Does it work on mobile?
