Mission

To each their own.

Our name starts with a Roman idea about justice, because it turned out to be the shortest way to say what we are building.

“Suum cuique tribuere.”

To render to each what is theirs. — Cicero, De Officiis, I.15

Cicero listed this among the duties of justice, and Roman jurists later put it at the head of their law. The phrase assumes something worth defending: that what belongs to a person should be returned to them, not kept by whoever is currently holding it.

It is an old idea and an unfashionable one. Nearly every useful piece of software now asks for the opposite arrangement.

The argument

The deal we all quietly accepted.

For twenty years the bargain has been the same. Software gets better when it knows you, knowing you requires your data, and handing over your data meant handing over control of it. So your mail, your calendar, your documents and your photographs went to companies who wrote the rules for what happened next — and kept the right to rewrite them.

AI does not extend that bargain so much as complete it. To be genuinely useful, an assistant needs the whole picture: what you wrote, who you answer quickly, what you keep putting off, what you said in a meeting last spring. Handing that over produces the most complete portrait of a person that has ever existed outside their own head — and under the usual arrangement, it becomes raw material for someone else’s product.

We think the premise is wrong, not the technology. Holding someone’s data does not have to mean owning it. A service can keep your data encrypted, use it only to serve you, refuse to share it, and hand all of it back the moment you ask. That is a choice a company makes, and it is the one we have made.

So we are building it that way. The models are open-source ones anyone can inspect, moving onto our own hardware as the waitlist grows. Your data is encrypted and never sold. Nothing is used for training, or anything else, unless you say yes. And every piece of it can be downloaded to your own machine, in open formats, whenever you like. What we sell is the software — not you.

The pace

Slower, on purpose.

AI is moving faster than most people can take it in. The largest labs are racing each other, and the rest of us are asked to keep up — with our jobs, our savings and the planet absorbing the cost of the speed.

We cannot call off that race. But much of the money behind it comes from ordinary subscriptions, and every subscription is a choice. Moving yours here moves it away from the biggest labs. If enough people do that, it slows them down. If it does not, it still sends a message they can count: people want this to go slower, and more carefully.

We want the good version of this future — the one where AI makes life genuinely better for nearly everyone. We think the way there is gradual: keeping the pain of lost jobs and economic strain as small as it can possibly be, rather than treating it as the price of progress, and protecting the environment along the way rather than spending it.

That shapes how we build. We choose efficient models sized to the job, not the largest one available. We grow at a pace people can actually adopt. And we would rather be useful than inevitable.

Commitments

Six promises, and what each one costs us.

A principle you pay nothing for is a slogan. Here is the bill for each of ours.

I.

Your data is encrypted, and we never sell it.

Encrypted in transit and at rest, with encryption we will keep upgrading as the state of the art moves. We do not sell, rent or broker it, and we do not hand it to partners. That is Level I, and it holds from launch. Level II comes at $5,000,000, when we run the models on our own hardware and your questions stop travelling to a provider to be answered. From then on, only you can share any of it. The two levels, explained.

What it costs us: the entire data economy. No selling your data to advertisers, no data partnerships, no quiet licensing deals. We have to win on the software alone.

II.

Only you can say yes.

The default is no. Using your data for anything beyond serving you — training our models included — requires your explicit, opt-in permission. You can see what you agreed to, and withdraw it at any time.

What it costs us: the largest free training set in this market. Every other AI company treats its users’ data as fuel. We have to ask.

III.

Download everything. We encourage it.

Every conversation, memory, file and setting can be downloaded to your own machine in open formats, whenever you like, as often as you like, with no restrictions. We will remind you to keep backups.

What it costs us: lock-in, the most reliable retention strategy in software. We have to be worth renewing every month on merit.

IV.

Open models, on our own hardware, then our own models.

We start on well-known open-source models that anyone can inspect, served through a trusted provider’s API. At $5,000,000 in reserved plans, we buy our own hardware and run them ourselves. After that, we build models of our own. On our side, the rules never change: your data is used to answer you, and nothing else. Until Level II, a request sent to the provider is governed by their terms — which is why we are working to bring it all in-house.

What it costs us: the comfort of standing still. Each step brings more of the work in-house, which is slower and costs more than simply reselling someone else’s model indefinitely.

V.

Each app has to be good on its own.

A mail client that only makes sense because it came with the AI is not worth switching to. Every app we ship has to stand comparison with the best in its category before we release it.

What it costs us: speed. A long roadmap shipped slowly, while others announce a suite in a quarter.

VI.

We say what we have not built yet.

Planned is marked planned. Undecided is marked undecided — including usage limits we have not set. You should not have to find the asterisk.

What it costs us: a less impressive first impression than the version of this page that simply lists everything as though it exists.

Boundaries

Things we have decided not to do.

  • Sell, share or broker your data to anyone, ever.
  • Train on your data without your explicit, revocable permission.
  • Use your data for anything you have not agreed to.
  • Make downloading your data slow, partial or hard to find.
  • Hold your files in a format only our software can open.
  • Send a model provider anything more than a question needs.
  • List something as available when it is planned.
  • Target ads at you without your opt-in, app by app. The default is no.
  • Race to be first at the expense of people or the planet.

From the team

We are a small group who think the last decade traded away more than it needed to, and that the coming one will ask for the rest unless somebody builds the alternative. We would rather make the version where you have unmatched and unequivocal control over your own things.

If that sounds right to you, join the waitlist and tell us what you would use it for. We are choosing what to build next from those answers.

Suum ex se. Yours, from you.
