June 9–12, 2026 · In collaboration with Anadal AI
Vibe code your idea to life.
The most outrageous AI build challenge of the year. Four days. Any AI tool. Ship something real — then demo it live at JUXTAPOSITION.
Enter the PROMPTHONA 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.
Virtual kick-off session. Form teams (1–3 people) or go solo. Receive the challenge prompt and theme constraints. Start building.
Heads-down building. Optional office hours and mentor check-ins via Discord. Share progress, get feedback, iterate.
Continue building. Prepare your demo. Submit your project repo and a 60-second video walkthrough by 11:59 PM.
Finalists present live on stage at the conference (5:15 PM). Audience voting. Awards ceremony. Glory.
Solo or teams of up to 3 people. All team members must be registered.
You must use AI tools (LLMs, copilots, generative models, no-code AI platforms) as a core part of your build process. Vibe coding is the point.
No pre-built projects. All code and assets must be created during the competition window (June 9–11). Open-source libraries and APIs are allowed.
Projects must address the competition theme (announced at kick-off). The theme will connect to AI's impact on business, creativity, or society.
Submit by June 11, 11:59 PM ET: a working prototype (deployed or screen-recorded), a public code repository, and a 60-second demo video.
Up to 8 finalists will be selected to present a 3-minute live demo at JUXTAPOSITION on June 12. At least one team member must present in person.
Projects are judged on: Innovation (30%), AI Integration (25%), Execution & Polish (25%), and Impact & Relevance (20%).
Respect, inclusion, and fair play. No plagiarism. No harmful or offensive content. Violations result in disqualification.
Anything that uses AI as a core ingredient. Here are some ideas to spark your imagination:
An AI-powered tool that helps small businesses automate a painful workflow
A generative art experience that responds to live data or audience input
A conversational agent that makes a complex topic accessible to non-experts
A creative tool that blends human input with AI generation in unexpected ways
An AI audit or transparency tool that reveals how algorithms make decisions
Something we haven't thought of yet — surprise us
