Your bag charm is alive.
A tiny AI pet that lives on your bag — it grows on your walks, your moods, your day.
Prototype · Built in publicToday's AI companions are $300+ desktop robots. They never leave the room — so they never see your actual life.
100M+ sold, and growing again. Taking care of a tiny pet never gets old — but Tamagotchi has no AI.
The biggest accessory trend right now. But they're all just decoration — none of them are alive.
Pini is the first AI pet you actually carry. Your steps, your moods, your meetings — that's what it lives on.
Go out together, it's happy.
Stay home too long, it turns away.
Its color shifts with you.
A mood ring with memory.
Crescent eyes and a soft
vibration in your hand.
Two Pinis say hi — and
reveal their compatibility.
One line about your day.
Sweet — but a little too honest.
When two Pinis get close, they see each other and say hi — and show whether they get along. Some pairs click. Some don't. They remember their friends.
Concept film. The real charms talk to each other over Bluetooth — no internet needed.
Every Pini draws its personality at random, the moment it first boots — you watch it happen. No two are alike, and how you live shapes what yours becomes.
Which one is yours? You'll find out when it wakes up.
It never dies, and it never makes you feel guilty. Its eyes blink and move like a real creature's — and how you live shapes what it becomes. Your pet becomes you.
Pini works on its own all day. It talks to AI exactly once a night. Here is everything that ever leaves the device:
| Brain | ESP32-S3 · Wi-Fi + Bluetooth LE |
| Face | 1.28" round LCD, glossy black lens |
| Senses | 6-axis motion · capacitive touch shell |
| Voice | None — it purrs by vibration |
| Body | Mirror-chrome crooked heart, metal clasp & chain |
| Sleep | Charging dock = its bed |
| Social | Pini-to-Pini over BLE, no internet needed |
| Price | Not set yet |
Eunhye Kim, Ph.D. (KAIST) shares every step of building Pini with her 110,000+ followers. This photo is the prototype running its pixel eyes on the real hardware — September 2026, one month after the first blink in a Shenzhen hotel room.
No. Ever. It gets upset, turns its back, goes cold — but it never dies. We don't want it to make you feel bad.
No. No microphone streaming, no speech recognition. It reads movement and touch, and sends only a numeric daily summary for its one nightly comment.
No app, no account, no notifications. One-time Wi-Fi setup; everything else happens on the device.
It goes through all three stages, and then takes a while to forgive you. A walk together fixes it — and that's the point.
No — it's random, decided the first time it turns on. Watching the roulette is part of the fun. (Yes, people will trade to get the one they want. We know.)
Pini is still a working prototype, built in public. Pricing and launch dates aren't set yet. Follow @linamond.insight for the waitlist.
