Anyone curious enough to open the box.
You don't need a factory, a lab, or a team. You need a soldering iron, some curiosity, and an afternoon. Whether you're a first-time builder or shipping your tenth project — CAIPO is for you.
You've printed enclosures, flashed firmware, and fried a few boards along the way. CAIPO is your next project. Source the parts, assemble it at your desk, and make it do something no one else has thought of.
Off-the-shelf wearables don't expose the right interfaces. CAIPO gives you full access to the hardware layer — swap sensors, write custom drivers, route data however you need. Bring Your Own Sensors.
There's no better way to understand embedded systems, I2S audio buses, or power gating than tracing it through real hardware. Every design decision in CAIPO is documented and open for you to read.
Our Multimodal Perception, Neuroscience, and Space teams are actively building the AI layer. If you've written a sensor driver, improved a case, or found a better part — send a PR. Your work ships to every future builder.
A wearable that works
for you — not against you.
Most wearables are black boxes. You can't see inside, can't change them, and can't trust what they do with your data. CAIPO is the opposite.
It processes everything on the device. It runs on open firmware you can read. And if you disagree with how something works — you can change it.
Everything runs on the device. Nothing goes to the cloud unless you want it to.
Don't like how the mic behaves? Swap the driver. Prefer a different chip? Fork the firmware.
No factory needed. No special tools. Designed to be built by one person at a kitchen table.
Every builder who pushes improvements makes it better for everyone who comes after.
Two chips. One clever trick.
Most wearables die fast because one chip does everything. CAIPO splits the work — a tiny always-on chip handles the basics, the powerful one wakes only when you need it.
This chip never sleeps. It listens for your tap, buffers your voice, and watches for the moment you need CAIPO — sipping so little power you'll barely notice it on the battery.
The moment you tap, it flips a switch and wakes up the powerful chip instantly.
This is where the AI lives. It handles your voice, talks to language models, and processes what the camera sees. But it draws zero power until the Sentry calls for it.
Not sleep mode. Not standby. Actual zero. That's what makes the battery last.
Four steps to your own CAIPO.
