The Altimist platform
Every other assistant drafts.
Yours finishes.
Altimist puts your documents, your mail and your money in one place on the internet — so the agent you control can reach them, change them, and settle up.
Not suggest. Do. One identity, one knowledge base, every surface — on the Mac, on your phone, and in the browser.

The product itself, one frame. Altimist open on a Mac: the left rail (Studio · Connect · Operations), a document on the canvas, Alti's console alongside it mid-task with a visible plan and a completed action. Real content, real numbers, no lorem. Shot in dark theme to match this page; a light-theme twin for the light toggle.

Why this exists
You've never been more capable — or more scattered.
Your AI tools don't share context, nothing carries over, and none of it is yours. You became the clipboard: carrying work between tools that were never introduced to each other, re-explaining yourself every morning.
Altimist puts it all in one place you own — every agent, every thread, one shared context that stays.
Three proofs
Things we can say, and the reason nobody else can.
In the order you'll feel them: the one that bites every week, the one that earns trust, and the one that changes what an assistant is for.
Proof 01 · the one you feel weekly
Your numbers changed. So did the deck.
Nothing in Altimist is a copy. The chart on slide four is the spreadsheet, seen from a different angle — so it cannot quietly go out of date while you are not looking.
Why nobody else says this: they cannot. A chart pasted into a slide is a picture of data that was true once.
Proof 02 · the one that earns trust
You can see exactly what it can reach. And take it back.
Your agent has its own name and its own key. Every document shows who can open it — including whether that is us. It is not a setting we promise to honour; it is arithmetic you can check.
Why nobody else says this: a plug-in runs as you, with everything you can see, and leaves no record that it was there.
Proof 03 · the one nobody else can say at all
It can pay.
Give it a budget and a limit. It watches the price, books the flight, settles the invoice, and tells you when it is done. An assistant that can only write is an assistant that hands the work back.
Why nobody else says this: an agent cannot transact without an identity the other side can verify. That does not exist yet. We are building it.
What you get
One place. Three workspaces.
Twenty-odd applications, folded into three destinations and one assistant. Nothing to integrate, because nothing was ever separate.
Studio
Writer, Sheets, Slides, Files — and the planning that goes with them. Say what you want; adjust the twenty per cent where your hand is faster than a sentence.
Explore Studio →Connect
Messages, mail and meetings in the same place as the work, so a thread and the document it is about are never two products apart.
Explore Connect →Operations
Agents, mandates, grants and the op-log. Who may reach what, for how long — and a signed record of everything that happened.
Explore Operations →Alti, in every workspace
One assistant, not a panel bolted onto each app. Alti routes each job to the cheapest model that clears it, so most of your work never touches a frontier model — and your bill knows it.
Altimist ID
A passkey, a handle, and one sign-in across every surface. Your biometrics never leave your device, and the same identity is what lets an agent act as a party rather than as you.

The return path, drawn as a diagram — the single idea behind “finishes”. Left: a conventional assistant returns prose that a human must carry back into the document (show the human as the hop). Right: Altimist returns an operation applied to the object itself, with the op-log entry beneath it. Two lanes, brand navy and sand, no stock imagery.

The foundation
Software was built for people to operate. It now has to be built for agents to act.
That is not a feature; it is a foundation — and foundations cannot be retrofitted. Five things had to exist before an agent could finish a job, and each one is a consequence of that sentence rather than a product we felt like building.
- 01
An agent must reach the work. The object graph — not files inside applications, but one addressable store the agent reaches directly.
- 02
An agent must be accountable. The op-log — every change signed, reversible and attributable to a named party.
- 03
An agent must be trusted with less than everything. Relationship keys — three folders, until Friday, revocable in one action.
- 04
An agent must be a party, not a costume. Finternet handles — its own name, its own key, resolvable by anyone.
- 05
An agent must be able to finish. Treasury — paying is the difference between advising and doing.
