Remi is your AI sleep companion. Not another tracker... a calm, present voice that helps you actually wind down, sleep better, and wake up clearer. Talk to Remi about tonight, tomorrow, or last night. He listens, remembers, and gives you one small thing to try, not ten. HOW REMI HELPS • Voice conversations that feel like talking to a thoughtful, expert assistant • A nightly Plan that adapts to your real sleep data, not a one-size template • Personalized notifications timed around your wind-down, not when it's convenient for us • HomeKit support — Remi can dim your lights or connect to other smart home devices • Remembers what you've shared across conversations, so you don't start from zero WORKS WITH YOUR RING, WATCH, OR WEARABLE Oura, Fitbit, WHOOP, Garmin, and Apple Watch — connect any combination via HealthKit. Your sleep data stays with you; Remi uses it to personalize, never to sell. BUILT FOR CALM, NOT ENGAGEMENT No streaks. No sleep scores to chase. No urgency. Remi is designed for the nervous system, not the dopamine loop. PRIVACY, CLEARLY • No third-party analytics in the app • Your conversations are processed by Anthropic's Claude (no training on your data, auto-deletion within 30 days) • Voice mode uses ElevenLabs — your audio isn't retained after the session • Delete your account and all data any time from Settings • Full policy at rhythmicly.com/privacy Remi is for anyone who's had enough of sleep tech yelling at them. If you've tracked for years and still aren't sleeping better, this is the companion you actually wanted. Made in Berkeley. Questions: colton@rhythmicly.com
