Your first tiny app

A tip-splitter, a chore wheel — you describe it, AI writes the code, you never touch it.

The lesson

Vibe-coding for absolute beginners: describe a tiny tool in plain English, let AI generate a single-file app, run it, and iterate by describing what's wrong. The point isn't the app — it's discovering that building software is now a conversation.

Try it — 60 seconds

Build me a single-file web page that [does one tiny job — split a bill, pick whose turn it is]. Make it work on my phone. I'll tell you what to fix after I try it.

Copy it into ChatGPT, Claude, or Gemini — whichever you already use. Fill in the brackets with your real life.

Watch out

Keep first apps toy-sized and personal. The moment an app touches other people's data or money, you've left the toy aisle — that's a different lesson.
