There are over 5 billion users using basic applications today such as email, notes, tasks and calendar, and they’re not AI-native. Our mission is to build proactive applications for anyone in the world who is not used to complex prompting. We aim to bring intelligence to conversations, errands, organising and workflows, with minimal to no prompting. Our first application is an agent-first mobile communication app. We believe building applications that users use daily for communication, coordination and collaboration will help integrate AI into their lives. The net effect is to eliminate misinformation, achieve low coordination costs, and enable high-quality tasks and collaboration at scale with minimal or little prompting.
