In this hackathon, you design before you build. Three days to plan your architecture. Six days to build with any AI tool. One day to prove that thinking first produces better results.
The difference? Here, the plan matters as much as the code.
And here's how we prove it:
Plan
Days 1–3
Design your project — architecture, features, and how you'll know it works. No code yet.
Build
Days 4–9
Build using any AI tool. Your plan is locked — changes require justification.
Present
Day 10
Present to global judges. Show how your plan became a product.
Solo builders and teams of 2–5. Join a city hub or participate virtually.
