A private AI that keeps your life at home.

Maison keeps what it learns about you in files on your own computer. You can read them, copy them, or delete them without asking anyone, including us.

Your information is never training data.

It stays with you

Your memory lives on your own computer.

Your files and everything Maison learns stay on your machine. You reach it from your phone over your own private network, and nothing is open to the internet.

The date, the $2,000 venue deposit, and that you want to keep it under 80 guests. It is all in your memory files if you want to read it.

It is plain files on your drive. Open them, look, and delete anything you like.

Conversations are examples. The one thing that leaves your machine is the thinking itself, which runs through your own account with the AI company. What runs locally

Questions

Questions about privacy.

Is Maison actually private?

Your files and the memory Maison builds stay on your machine, in files you can open, copy or delete yourself. Your conversation thread is scoped to your own account alone and is never pooled with anyone else's. Your information is never training data.

Do you train on my data?

No. Not your conversations, not your files, not your memory, and not now, not quietly, not later. What moves between machines is craft, not content: when your Maison works out a better way to do something, the method travels and everything identifying you or your work is stripped out before it goes. Your transcripts are not in that pipeline at all.

What actually leaves my machine?

The reasoning. It runs through your own account with the model provider, which you sign in to once during setup, and it bills to you directly under your terms with them rather than ours. We are not in the middle of it and we do not mark it up. Everything else stays on your disk.

Can anyone reach my Maison from the internet?

No. It is reachable from your phone over your own private network only. There is no public address and nothing is exposed to the internet, so there is no door to knock on.

What happens to my data if I cancel?

You keep it. Cancel, unplug or walk away entirely and the memory is still on your disk and still yours. It is not held hostage to a subscription.

Can I keep my memory somewhere other than my own machine?

If you would rather not keep it yourself, we can hold it for you in a space of your own, kept separate from everyone else's. You choose this during setup. Your own machine is the default.

Ask us the hard version of the question.
