Introducing Biyo

World's first AI assistant
you can wear.

Biyo is a wristband that gets things done. Double tap, say what you need, and it books the table, clears the inbox, makes the call, and comes back with confirmation.

The two you can't make

Made for your kind of busy.

Whatever fills your day, Biyo takes the admin off it.

The professional
The professional
Sends the recap, moves the meetings you can't make, replies to the emails you've been avoiding.
The founder
The founder
Reschedules the investor call, books the dinner, chases the invoice. You stay on the product.
The parent
The parent
Books the doctor, orders the school shoes, sets up the carpool. Said once, in passing, done.
The freelancer
The freelancer
Sends the invoice, chases the late payer, cancels the tools you stopped using. Admin handled, you bill hours.
The traveller
The traveller
Rebooks the flight, moves the hotel, orders the airport car. Delayed? It claims the refund.
The executive
The executive
Clears the inbox, declines what doesn't matter, confirms what does. A chief of staff on your wrist.
The salesperson
The salesperson
Books the follow-up before you've left the room. Sends the proposal, updates the deal, sets the reminder.
The athlete
The athlete
Logs the session, books the physio, reorders the supplements. You train, it handles the rest.
The app

Talk.
Biyo handles it.

Say it once, mid-conversation, hands full, wherever you are. Biyo makes the call, books it, sends it, and tells you when it's done.

You say
"Book me a table for four on Friday, somewhere Italian."
"Email the energy company and sort the overcharge on last month's bill."
"Tell Sarah the deck's coming Monday and move our 1:1 to Thursday."
"Cancel any subscriptions I haven't used in three months."
"Get me on an earlier flight tomorrow and a car to the airport."

How it works

Double tap.
Consider it done.

No screen. No app to open. Double tap, say what you need, and get on with your day. Biyo tells you when it's handled.

Taps to hand it off 2 That's the whole process.
Live status
Listening
"Call the dentist and move Thursday's appointment to next week." Say it the way you'd say it to a person.
00:00:00
7 days.
One charge.

Monday morning to Sunday night without touching a charger. An assistant that dies by lunch can't take your afternoon's calls.

How it works

Three steps.
None of them on a screen.

Hand off a task the way you'd hand it to a person standing next to you. Then get on with your day.

1
Double tap.
Double tap the button on the side of the band. The light comes on, Biyo is listening. Only then, never before. No wake word, no always-on mic.
Double

2
Say what you need.
"Book the dentist." "Call the bank about that charge." "Move my 3pm to Friday." Say it the way you'd say it to a person. Biyo takes it from here.
3
Consider it done.
Biyo makes the call, sends the email, books the slot. You get a confirmation with the details. Anything that spends money or speaks in your name waits for your yes.

how people work.

"I was sceptical. I have a Notes app, I have Siri, I have everything. But Biyo is the first thing that actually works passively. I don't have to remember to use it. That's the difference."

FAQ

You've got questions.
We've got answers.

Everything you need to know before you order.

A personal assistant on your wrist. Double tap, say what you need, and Biyo makes the call, books the appointment, sends the email or cancels the subscription. It does the task, not just notes it down. You get a confirmation when it's done.
Double tap the button on the side of the band. The light comes on and Biyo is listening. Say it the way you'd say it to a person: "Book the dentist for Thursday" or "Call the bank about that double charge." No commands, no settings, no wake word. Biyo takes it from there.
Every task comes back with a receipt: what was booked, who was called, what was said, what it cost. If something can't be done, Biyo tells you why and what it needs instead of pretending it worked.
Not for anything that matters. Anything that spends money, sends words in your name, or can't be undone waits for your yes. Rescheduling, checking availability and sitting on hold happen without you. Paying, cancelling and sending need one word from you first.
Yes, in your pocket or your bag. The band talks to the Biyo app over Bluetooth, and the app does the work. You never need to take the phone out, but it needs to be within range for Biyo to act.
Yes. Double tap at the start and Biyo listens for as long as you need. Afterwards it sends the recap and turns the action points into actual actions: the follow-up gets booked, the email gets drafted, the reminder gets set. Recording laws vary by country, and in professional or sensitive settings you should let people know.
iPhone and Android. The Biyo app is free on both. The band pairs once and stays paired.
Biyo understands 79 languages. Say it however you think.
No. The microphone only turns on when you double tap. No wake word, no background listening. Single tap pauses it mid-session, double tap ends it. The light tells you which state you're in.
You. Your requests, recordings and task history are encrypted in transit and at rest. Nobody at Biyo reads them, and nothing is shared with anyone who isn't needed to complete your task.
Never. No advertising business, no data brokers, no partnerships that trade on what you say. Your conversations are not a product.
Only what the task needs. Booking a meeting sends the event to your calendar. Replying to an email goes through your inbox. Your recordings never leave Biyo. The apps see the action, not the conversation.
Yes. One task, one day, or all of it, whenever you want. Gone means gone, on our servers too.
7 days on one charge with normal use: a few handoffs a day plus the odd long meeting. Heavy use, like hours of continuous listening every day, will shorten that.
About 90 minutes from empty to full on the magnetic cable in the box. Most people charge it once a week while they sleep.
Nothing. Once you've said it, the task is with the app, not the band. Biyo keeps working on your phone and the confirmation is waiting when you're back.
Yes. The band is IPX7 rated: showers, rain, sweat and a drop in the sink are fine. Don't take it swimming.
The Biyo app is free. Everything described on this page is included with the band at no monthly cost. If we add premium features later, they'll be optional.
Two finishes: All Black and Taupe. Pick yours at checkout.
Biyo Band, magnetic charging cable, quick start guide. The app is a free download on iOS and Android.
Pre-orders ship in 2 weeks. After dispatch, UK delivery takes 2 to 4 business days; international varies by destination. You'll get a tracking link the moment it leaves.
Send it back within 30 days for a full refund, no questions asked. Every band comes with a 1 year warranty.
