Why Every AI-Built Site Looks the Same, and How to Fix It
Every AI-built site looks the same: purple gradient, Inter font, one centered button. That is not your fault. AI has terrible taste by default, so when you vibe code it reaches for the same generic look every time. The fix is not a better prompt. It is a stack of sites you keep open that hand your AI great taste instantly. Here are all 17, plus the exact prompts to paste into Claude.
The 5 from the video
1. 21st.dev 21st.dev ★ 5,347 on GitHub
A marketplace of beautiful UI components that real designers built. Find a hero, a pricing card, a bento grid you like, copy it, and paste it straight into your site.
2. Aceternity UI ui.aceternity.com
Prebuilt, smooth animations (spotlight, moving border, aurora, text effects). One drop-in component is what makes a site feel expensive instead of flat.
3. Magic UI magicui.design ★ 21,565 on GitHub
The companion library to Aceternity: marquees, shimmer buttons, animated lists, blur fades. More polished motion you can paste in with zero animation code.
4. Mobbin mobbin.com
A huge library of real screens from the best apps in the world. Use it as the reference you hand your AI: copy how the pros handle spacing, hierarchy, and flows.
5. tweakcn tweakcn.com ★ 10,171 on GitHub
A visual theme editor for shadcn/ui. Kill the ugly default black and white and default font in one click, then export the CSS variables and paste them into your project.
