01

What Is It?

A four-day AI build sprint where you use prompts, copilots, and generative tools to ship a working prototype from scratch.

The PROMPTHON is not a traditional hackathon. There's no boilerplate. No starter code. You begin with nothing but an idea and a prompt — then vibe code your way to a working product using any AI tools at your disposal. Think of it as entrepreneurship at the speed of thought.

On the final day (June 12), selected builders demo live on stage at the JUXTAPOSITION conference. The audience votes. Winners are crowned.
