Lumio Copilot — A private personal assistant for your iPhone.What it does
A quiet companion for the noise.
Six small habits that quietly keep the rest of your day from getting away from you.
Drafts and replies
A starting line for the message you keep putting off. In your voice. Editable, never sent without you.
Notices and nudges
A friend you forgot to call back. A bill that crept up. A meeting that drifted into another. It catches the slips.
Voice when you’d rather speak
Hold and talk. Audio stays on your iPhone. Transcription happens locally — no cloud round-trip.
Morning briefings
Tomorrow, gathered overnight while you charge. Your day, the weather, a few things to know — one calm glance.
Lives where you live
Lock-screen, home-screen widgets, Live Activities, Siri, Focus modes. It shows up where you already are.
Private, by ground truth
On-device by default. Not a toggle. The ground truth.
Most apps that promise privacy bury the truth in a settings screen. We started from the other side: the assistant runs on your iPhone, on the silicon you already paid for. Cloud is the exception, marked every time.
Lives on your phone.
Apple Intelligence Foundation Models, plus Qwen 3.5 (4B) running locally via MLX-Swift. Calendar, mail, reminders, voice — read, indexed, and answered from your device.
No trackers. Ever.
Zero third-party analytics SDKs. No behavioral profiling. Crash reports scrub identifying data before they leave the phone. Nothing is sold; nothing trains a model.
Cloud is opt-in, per feature.
Turn web search on and your provider sees that query — but we do not. Every cloud-touched response wears a small tag so you always know what left the phone.
Bring your own context
Tell it about you, once. It remembers.
On day one, paste a snippet from your notes — about the people you care about, what you want to focus on, the frustrations to avoid. Your assistant reads it once, builds a memory, and never stores the pasted text.

Built calm
It respects your attention.
You set the budget. The assistant lives inside it. We never optimize for engagement — we optimize for not bothering you.
A handful of timely nudges. The default.
Try it. Drag the candle, tap a label, or use arrow keys.

Questions, answered plainly
A few things people ask.
It’s a personal assistant. The intelligence runs on your phone. You don’t have to think of it as an AI app any more than you think of your calendar as a database app.
Light it once. Let it work quietly.
A small candle on your home screen. A calmer week underneath it.
