Not a wearable.
corii doesn’t track your health or manage your day. It doesn’t have apps, calls or a feed to check. It’s the first device built for the world you’re already standing in — no screen between you and it.

Built to be felt
What the core is designed to do. Planned means we intend to ship it. Concept means we are still exploring it.
Standalone from day one
Genesis OS. Designed to work out of the box with no phone. The companion app is for setup, custom patterns and your data.
Tap to switch modes
Double-tap the titanium face to change modes. A long press authorizes. No screen needed.
Sound you can feel
Low-frequency haptics designed to let you feel the low end of a track in your core. A side connection, not the main one.
Biometric key
Designed to read your continuous body rhythm as a key. Take corii off and it locks.
Emergency alert
A discreet multi-tap gesture designed to send your location to people you trust. Not a medical or emergency service.
Fit for every navel
Polymer mounting rings in several depths and widths, because navels are not one size.
Magnetic snap-fit
Rare-earth magnets lock the core into its ring with a click and release it for charging. Desk dock and pocket capsule in concept.
Bluetooth LE + UWB
Short-range radios for proximity handshakes and your wider ecosystem.
Operator profile
Focus and flow. Designed to pace your work with a steady, low pulse so your attention stays where you put it.
Athlete profile
Recovery and breath. Designed to guide slow, even breathing after effort with a gentle rhythm.
Ghost profile
Stealth. The core stays dark and silent and only authenticates. Designed for privacy.
Paired cores
Two cores, one signal. Designed to let two people share a pulse across any distance.
Concept render. Specs are design targets and may change before release. corii is not a medical device.
The first, last, and lost connection.
corii is not a wearable, and it does not manage your health. It is the reattachment of a sense you had before you had a name for it — lost at birth, found again at your center.
corii doesn’t speak English.
No app to open. No login. No interface to learn. corii answers to breath, pulse and stillness — the first language, spoken before any other. You don’t operate corii. You remember how.
First, last and lost connection
The navel is the first connection any of us has: the line to our mother. It is cut within minutes of birth, and after that nobody gives that spot a job again. corii is built to reconnect it.
最初の接続 · 失われた接続 · 最後の接続
The sixth sense, reattached
Five senses were named and taught. The rest — hunger, tension, gravity, rhythm, the pull of a room — were left unnamed and mostly unheard. corii listens where the others don’t: at your center. Not a new sense. The one you already had.
corii breathes.
No screen. No keyboard. No language built for typing. corii turns the digital world into something you feel in your body, the way you already feel fear, hunger or calm arrive before you can name them. You do not look at data. You never did.
The Oasis
The internet doesn’t disappear. It becomes a place you visit on purpose — not the place you live by default. corii keeps the real world as home, and lets the digital one be what it was always supposed to be: somewhere you go, not somewhere you’re stuck.
Screenless sovereignty
- No apps, no calls, no feed. corii doesn’t rebuild what a phone does — it makes most of it unnecessary.
- Your presence is the password. No logins, no cards, no PIN to forget.
- Head up. World open.
Are you tethered?
Ask someone if their phone is connected and you get a yes or a no. Ask if they are tethered and you ask something older: do they still feel the line to their own body? You are not only online. You are alive in the network.
The game you were already in
- Life was never flat, ordinary or boring. It was a game with the sound turned off.
- corii turns the volume back on: timing, instinct, presence — things you were born knowing.
- You don’t start playing a game. You wake up inside the one you’re already in.
A language with no letters
Every device before corii needed you to learn its language: taps, swipes, passwords, typing. corii is the first that learns yours. Breath. Weight. Stillness. Presence. You already speak it fluently. corii is just the first thing built to listen.
The severance
Humanity’s highest-bandwidth router was severed at birth. We filled the void with screens and called it progress. You are not connected. You are confined. corii is built to reconnect the line.
The correction
The future was supposed to be light, weightless and connected. Flat glass was a detour. Head up. World open. Timeline correction: in progress.

Help build corii.
corii is independent and built by Khuma Deep Tech Labs. Funding goes to prototypes, sensors and actuators, safety testing, and the open SDK.
Other ways to help
- Join the waitlist and tell one friend.
- Developers: build on the open SDK.
- Engineers, designers, testers: get in touch.
Open source.
The corii SDK and firmware docs will be public, so anyone can map custom functions to the core.
Planned
- SDK for JavaScript and Python
- RISC-V firmware documentation
- Haptic and light pattern library
- Haptic macros: map any data stream to a pattern you feel
- Node dev kit for ambient, screenless services
- Hardware specs and mounting files
corii.on("signal", s => {
