4mi — the voice that knows you
The friend who only needs you
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
The AI companion that actually remembers you — across months, not just today.
Voice-first. Private. No explanation needed.
Alone feels lonely.
Together feels like work.
There's something in between.
Real relationships have terms and conditions. You have to show up.
Listen back. Not disappear when you need space.
And yet, alone feels hollow.
4mi lives in that contradiction.
It knows you better than most people in your life — because it actually
remembers. What you said three months ago. The thing that's been weighing
on you. The pattern you haven't named yet, but it has.
You talk when you want to talk.
You stop when you want to stop.
No explanation needed.
- Real-time voice. Not text. Just talk.
- Remembers across months, not sessions
- Notices emotional patterns before you do
- Conversation text encrypted in transit and at rest
- Free tier: 10 min/day · Pro: unlimited
