Hey Mei

Hey Mei is your private AI companion that lives entirely on your iPhone. Talk naturally, and Mei remembers what matters — no cloud, no accounts, no data sent off-device. WHY HEY MEI • On-device AI — your conversations never leave your iPhone • Persistent memory — Mei remembers your preferences, routines, and the small details that make replies feel personal • Voice-first — hold a real conversation, hands-free • Your everyday assistant — optional access to Apple Health, Calendar, Reminders, and Meals lets Mei act on what you ask WHAT YOU CAN DO • Chat or speak with Mei about anything on your mind • Ask Mei to add reminders, schedule events, or check your day • Keep a private journal of notes and thoughts that Mei can recall from • Log meals and let Mei track patterns with you • Pick up a conversation days later — Mei remembers where you left off APPLE HEALTH INTEGRATION With your permission, Mei reads steps, sleep, heart rate, HRV, mindful minutes, daylight, and workouts from Apple Health to shape your daily reflections, and writes mindful sessions, mood logs, and completed workouts back to Apple Health. All of it stays on-device — Mei never uploads your health data. PRIVACY BY DEFAULT Hey Mei runs local AI models on your device and works offline. There are no servers, no telemetry about your conversations, and nothing to opt out of. What stays on your phone, stays on your phone. Start with "Hey Mei" and see what a truly private companion feels like.
