I Built an App with GPT in a Day

It started as a challenge: could I build a working app using GPT in just 24 hours? Fueled by coffee and curiosity, I dove in headfirst.

The Stack

Next.js for the frontend
OpenAI API for the brains
Vercel for instant deployment
A lot of trial and error

The Process

"Move fast and break things" was my motto for the day.

I started with a simple prompt and a blank page. Within hours, I had a chatbot that could answer questions, generate stories, and even write code snippets.

// The first working prompt
const response = await openai.createCompletion({
  prompt: "Tell me a joke about AI",
  max_tokens: 50,
});

Lessons Learned

GPT is powerful, but context is everything
UI/UX matters, even for a quick hackathon
Sleep is optional, but bugs are not

Would I Do It Again?

Absolutely. The app wasn't perfect, but the experience was invaluable. Next time, I'll bring more snacks—and maybe a teammate.
