  • Hackathon winners highlight AI’s potential in community solutions

    Two innovative apps that combine technology with community-driven solutions took top honors at a recent hackathon in Quezon City, signaling the growing role of AI-driven tools in addressing everyday challenges. The winning projects, BetterBee and EcoCycle, were announced during the event hosted at High Grounds Café on November 3 by the Internet Computer Protocol (ICP) Hub Philippines. The hackathon centered around Caffeine AI, a platform that lets users build apps simply by chatting with artificial intelligence. This is what organizers call the “self-writing internet,” where app development does not run on traditional coding.
