25 AI Hackathon Ideas for 2026 That Focus on Real Problems, Not Novelty

GenAI engineer and three-time hackathon winner Pranjul Rathour has published a curated list of 25 AI project ideas aimed at hackathon participants heading into 2026. Each idea is paired with its single hardest technical challenge, such as handling noisy data, ensuring extraction accuracy, or building reliable escalation logic. The list spans domains including agriculture, education, healthcare, civic services, and small business tools. Rathour argues that judges reward demonstrable solutions to real user problems over novelty alone. He recommends that teams pick the idea whose hard part genuinely interests them and narrow it down to a single, well-scoped demo path.
