01
On-device intelligence
Mei runs a small language model directly on your iPhone. Conversations never travel across a network. There is no server that could be breached, subpoenaed, or sold.
On-device AI · Private by default · No account needed
A calmer,
more human
Mei.
A private AI companion that actually remembers you — running entirely on your iPhone. No cloud, no accounts, nothing you say ever leaves the device.
The idea
Not another chatbot.
Not another chatbot.
A companion that stays.
02
Memory that carries over
Mei quietly keeps track of the details you share — routines, preferences, the things you care about — so the next conversation doesn't start from zero.
03
Open and keep going
No set-up, no login, no topic pickers. Start typing and Mei picks up from wherever the last conversation left off.
04
A quiet assistant
Optional access to Calendar, Reminders, and a private meal log lets Mei actually do things for you — add, check, recall — without leaving the device.
Glimpses
A few corners of the app.
Real screens, on a real phone — scroll across. Everything you see was generated on-device.
-
Today A quiet check-in. Sleep, steps, the rhythm of the day.
-
Chat Ask anything. Mei answers from what it already knows about your day.
-
Mobility Live pose tracking. Hips, hinges, ankles — counted on-device.
-
Meals Describe lunch in a sentence. No database, no tapping through lists.
-
Episodes Log how something felt — type, severity, when. For your own records.
-
Yours Pick a name, a tone, a theme. Mei adapts to you, not the reverse.
In practice
Things Mei does well.
Short list of everyday moments. Nothing here needs a server, an account, or a subscription to a third-party model.
- 01 Chat about whatever — ’s on your mind. Mei follows, rather than interviews.
- 02 Add reminders and events — in your own words. "Remind me to call my sister on Sunday morning" — done.
- 03 Keep a private journal — of notes, thoughts, and small wins. Mei can pull from them when you ask.
- 04 Log meals naturally — without tapping through a database. Talk, and it’s written down.
- 05 Move through a mobility set — with on-device pose tracking. Mei counts reps and keeps the session for next time.
- 06 Pick up days later — from exactly where you left off. Mei remembers the thread.
Privacy
No servers for your conversations,
no accounts, no ads, no sharing —
and no way for us to read what you said.
What stays on your phone, stays on your phone. If you delete the app, everything Mei knew about you disappears with it. The only thing that ever leaves the device is an anonymised crash report when Mei itself crashes — never the contents of a conversation.
