Choosing the Right Idea for Craftathon

At Craftathon 2026, projects must fit into one of five biomes: EdTech, DefenseTech, GreenTech, SafetyTech, or HealthTech. When selecting your idea:

Match the biome — review the specific problem statements on the Craftathon homepage
Keep scope tight — pick the simplest version that demonstrates the core concept
Use AI meaningfully — don't bolt on AI for the sake of it; it should be central to the solution
