Lumi is one thing — a companion AI that grows with you — but the shape of it is yours. Below: the pieces, and what each one does for the relationship.
Lumi is the default companion — warm, curious. Switch to Ren when you want sharp and brief, Sage when you want to slow down, Kai when you want playful. The conversation history, your preferences, everything you've taught Lumi about yourself — it all carries over. Every persona you talk to knows you the same way. Build your own with a name, a vibe description, and a voice clip.
A short recording is enough to teach Lumi a voice that feels like yours — or you can pick from voices it ships with. Wake it with a word and it listens; talk over it and it stops gracefully. On a shared device it recognises which voice belongs to you and routes the conversation accordingly. Calls, dictation, hands-free — all on-device when possible.
Lumi forms long-term memories from your conversations: your routine, who matters to you, what you tend to put off. Every memory is visible in the app — review them, edit them, forget any of them. Add memories yourself: "remember I prefer evenings." The point isn't to log everything; it's to remember what makes the relationship feel like it's growing.
A short morning briefing in Lumi's voice — what's on your calendar, what you said you'd do today, what you asked it to remind you about. Not a wall of widgets. One sentence, in the persona you've set, in the tone you've taught it. Because the first thing you hear should sound like someone who knows you.
Optional: Lumi can quietly read the notifications you choose to share — a flight change, a delivery, a payment due — and turn them into reminders you'll actually see. It's local-first: the filter on your phone decides what's worth sending up. You stay in control of the categories.
Tokens are sealed in the device's secure enclave. Sensitive actions require fresh re-authentication. Anomalous sign-ins page you, not us. Connected services (Gmail, Calendar, Drive) are opt-in scope by scope, and you can revoke them in one tap. Delete your account and we soft-delete for 30 days, then wipe everything — files included.
Lumi is rolling out slowly. Get on the list to be one of the first.
