UI Promptbook

UI Promptbook started from a pretty simple frustration: every time I vibe coded an app with Lovable or Cursor, I found that not only did my websites look the same as each other, but also same as everyone else using these tools. The problem was that we often tell these tools what we want the app to do, but not how we want it to look like. I realised how AI works. It predicts based on probability. Without guidance, the AI would default to the most statistically average design it knew. That's when I built UI Promptbook, a library of detailed UI design prompts that you can simply copy and paste when building your own apps.
