Meet Mya · Early testing

A thought.
A plan.
Your say.

“We need milk.” “People are coming over.” Mya prepares the change in a private chat. You check it before anything is added.

Nothing changes until you confirm
Mya prepares the change and shows it to you first. You can change any line before it is added.
Private to you
Your Mya chat sits in Messages and belongs to you. Housemates and house admins cannot read it.
Works without AI
Simple flows handle the requests Mya has been built for. Nothing is sent to an AI model.
AI help, one request at a time
If you turn on AI help, a request goes to an AI model only when you choose Clear a request and allow it. It is sent to Anthropic, which may process it outside Australia.
Money stays in Bills
Mya can start a bill draft. It does not create bill records or settle payments; amounts are checked in Bills.

Mya is in early testing and is turned on for a small group of people. It is not available in every house yet.

Cleaning

Every task has an owner and a date.

Routines come back on their schedule. If a day doesn't work, a swap or an offer keeps the house in the picture.

A few practical answers

Before
you move in.

All questions
Is CoExyst a shared house app?

Yes. CoExyst is for share houses, housemates, couples and families who run a home together. Cleaning, shopping, bills, the calendar, messages and house information live in one place, so the house does not depend on scattered chats, notes and one person's memory.

Can CoExyst help housemates manage cleaning?

Yes. Cleaning tasks and recurring routines have owners and due dates, and housemates can swap or offer a task. Everyone can see what is due and who has it. CoExyst does not enforce housework; it gives the house a clear record of what needs doing and who has taken it on.

Can CoExyst track shared bills and repayments?

Yes. Each bill records its due date, how it is split, each person's share and whether it has been repaid or confirmed. CoExyst does not make payments or connect to your bank; it keeps the record the house can check later.

Can housemates keep personal shopping or spending private?

Yes. My List and private bills stay with you. The house sees shared lists and shared bills; where a private record would appear, the house sees that something is hidden, not what it is.

What is Mya?

Mya is a private chat in Messages that prepares changes for you: shopping items, cleaning tasks, reminders, calendar events, people over and bill drafts. You check each change before it is added. Mya is in early testing and is turned on for a small group of people; it is not available in every house yet.

Does Mya send my messages to an AI model?

Not unless you choose to. In simple flows, nothing is sent to an AI model. If you turn on AI help, a request is sent only when you choose Clear a request and allow it. That request and your recent messages in the Mya chat go to Anthropic, which may process them outside Australia. Housemates and house admins cannot read your Mya chat.

Does CoExyst replace a house group chat?

It doesn't have to. Housemates can still chat wherever they like. CoExyst gives the repeat admin a proper place, so bills, cleaning, shopping and decisions are easy to find later. Bill requests and task assignments go to your Inbox, not into chat.

How does early access work?

Request early access and tell us about your household. Each request is reviewed by a person, and access opens in waves. A request does not guarantee access or a date, and no account is created until your house is invited.

Can CoExyst be installed like an app?

Yes. CoExyst is an installable web app on supported iPhone, Android and desktop browsers. The install page shows how to add it from Safari or a supported Chromium browser. CoExyst is not on the App Store or Google Play.
