Jammy, a voice-first wellness app, is creating an emotional operating system through music by combining conversational AI with emotionally aligned music recommendations. The platform uses Hume's Empathic Voice Interface (EVI) to detect how users sound, not just what they say, powering real-time content recommendations that feel emotionally resonant and deeply personal. This has led to a 109% increase in monthly active users, driven by emotionally intelligent experiences that meet users where they are. The platform aims to reduce friction and boost engagement through natural, intuitive experiences that enable users to speak freely like they would to a trusted friend, receiving playlists, prompts, or support tailored to how they actually feel.
