The System

IntroducingMaison.

An assistant that installs on your own Mac, remembers everything you have built together, and goes and does the work rather than talking about it. Private, persistent, and running on hardware that belongs to you: not an account on someone else's machine that can be changed, priced, read, or switched off without asking you.

Installs on your own Mac Your memory stays on your disk $799 a month, plus $250 a person
What arrives

A file you download, not a service you log into.

Most AI is a website, and your conversation lives on somebody else's server. This is software. It lands on your computer, sets itself up, and from then on the thinking, the listening and the remembering all happen somewhere you can point at.

01

The assistant

Voice and chat, running on your machine and reachable from your phone over your own private network. No public address, nothing exposed to the internet.

02

The memory

A private database on your own disk. Everything it comes to know about you is a file you own, that you can read, copy, back up, or delete without asking anyone.

03

The models

The parts that hear you, speak back, and search your own memory run locally. Those never leave the machine, so they keep working with the network off.

You are not renting access to a mind that lives somewhere else. You are installing one. Exactly what runs locally, and what does not.

The library

It learns by doing, and it does not forget how.

Every time it works something out it writes down how, and that becomes a skill it keeps. Below is the actual library on the machine this page was written on, written out in plain words rather than the shorthand it files them under. Pick a department and push the shelves sideways.

None of this was planned. It is the residue of six months of real work, which is why it reads like the work rather than like a feature list. Yours will end up looking like yours.

What it does

Ask out loud. Come back to it finished.

The difference between an assistant and a colleague is whether the thing gets done while you are somewhere else. Everything below runs on your machine, on its own, whether or not you are watching.

Hold to talk, or just start talking

It listens and it answers

Talk to it from your phone, your desk, or the car. The speech goes to your own machine and the voice that comes back is generated there too. Talking to it.

It remembers everything

Not one conversation. Every conversation, every person you have mentioned, every decision and the reason behind it. You never introduce yourself twice.

It does the actual work

Give it something real. It goes away, does it, and comes back with the thing itself, along with what it found and what it decided along the way.

It handles the mail

It reads what comes in, tells you what matters, drafts what needs a reply, and sends the ones you have told it it can send. How that works.

It works with your people

Every project gets a room. The people you invite are in it, and so is Maison, following what is being decided and building what gets asked for.

It keeps going overnight

It tidies what it learned, follows up on what it promised, and is further along in the morning than where you left it.

What it needs

Real numbers, measured on a real machine.

These are not estimates. They come from the computer this was built on, after six months of the heaviest use anyone has put it through.

16 GBMemory to run, 24 GB or more to run it comfortably
1.2 GBWhat six months of heavy daily use actually adds up to
ZeroOf your conversations stored on our servers by default

A Mac with Apple Silicon

The models run on your own chip, which is the whole reason any of this is possible on a personal computer.

Required

Your own Claude account

You sign in once during setup and approve it, the same way you would sign in to a code editor. Your conversations bill to your account, under your terms with Anthropic, not ours. We never sit in the middle of them.

Required, billed separately

About 25 GB free, and an hour the first time

Most of that hour is downloading the models. You are turning a computer into something it was not before. It is reasonable that it takes a moment, and it tells you exactly where it is the whole way.

First run only
Setting it up

Four steps, and then it is simply there.

There is no terminal, no configuration file, and nothing to read beforehand. It asks you a small number of questions and does the rest itself.

Maison is running. It will still be running tomorrow without you doing anything at all.
01

Download and open it

One file from this site. It opens like any other Mac application, and the first thing you see is a window, not instructions.

02

Sign in to Claude

A browser window opens, you approve it once, and it closes. From that point your Maison thinks using your own account.

03

Say who you are, and where your memory lives

It asks your name and a little about you, because that is the beginning of it knowing you. Then you choose whether its memory sits on your machine or with us.

04

Let it finish

It downloads what it needs and sets itself up, showing you each stage as it goes. When it is done it is already running, and it will still be running tomorrow without you doing anything at all.

Where your memory lives

On your disk, unless you ask otherwise.

Six months of the heaviest use we have measured came to 1.2 GB. Memory is small. That is why keeping it on your own machine costs you almost nothing, and why we would rather you did.

On your machine

The default, and included. Everything it knows about you sits in a database on your own drive. If you cancel, unplug, or walk away entirely, the memory is still there and it is still yours. Nobody can read it remotely, and that includes us.

IncludedRecommended

Hosted by us

If you would rather not keep it yourself, we will hold it in a database of your own, kept separate from every other person's. It costs extra, because hosting costs us money and we would rather charge for it honestly than pretend it is free.

Additional monthly fee
Free your mind

Two ways in. Both of them early.

These are the early numbers, and we would rather explain them than dress them up. There are few enough of these running that we know every one of them by name, and at that size the price is not really for software. It is for the software and for us: the setup, the machine it lands on, and the work of shaping it around what you actually do.

One machine
$799
a month, plus $250 for each person you add, up to four

Everything on this page, on one machine that belongs to you. Your memory on your own disk, the whole library, and a person from here for as long as the setup takes. Yours alone at $799. Bring up to four colleagues onto it and each of them is $250, however they use it. More than that is a company, and the tier beside this one.

  • Installed on your own Mac, in an afternoon
  • The memory is yours, and stays yours if you leave
  • $250 a person, whether they write to it, talk to it, or build with it
  • Up to four people besides you; we will tell you when you are close
  • Your Claude account, billed by Anthropic, never marked up
  • Questions answered by someone who built it
A company
$5,000+
a month, quoted once we understand the shape of it

The same system for a team, with a room for every project, people who can come and go, and nothing crossing between clients. Priced per company, because no two are the same size or the same shape.

  • A room for every project, and a member of the team in each one
  • Isolation between clients, enforced rather than promised
  • Set up with you, against the way you already work
  • Run on your hardware or ours, your choice

What the price is doing

Early means it still takes people. Every install gets a person, questions get answered by someone who built it, and what you run into in the first month becomes next month's software. Bringing the number down is the plan, and the way it comes down is the software needing less of us.

Early access

Your Claude account

Paid to Anthropic directly, at whatever their rate is. We take no part of it and we do not mark it up. It is your account and your relationship.

Billed by Anthropic

Hosted memory

Only if you choose it. Keeping your memory on your own machine is the default, and it costs nothing.

Optional

Everyone deserves a mind of their own. Not everyone can pay this, and we are not going to pretend otherwise. It is high because it is early, and the whole point of the work is to make that stop being true.

Ask to see it work.

Ten seconds of watching it run beats every word on this page. Tell us what you would hand it first, and we will show you the same thing we use every day.
