Set up Thinair
and run your first task.

Get Thinair and open it.

Thinair for macOS is free, with no account needed. Thinair for Windows is coming. Download Thinair for your computer, or sign up for Thinair Cloud to run apps in Cloud and in your browser.

On macOS

Download Thinair for macOS 26 or later, on Apple silicon. Open the disk image, move Thinair to Applications, and open it.

The first time it opens, Thinair needs the internet: it fetches the rest of itself from its signed update feed and checks each piece before it runs. Its background service shows as ThinairOS.

After that, Thinair updates itself and starts even when you are offline. An update to the app itself waits until you choose Restart to update, and your Terminals keep running through it.

On Windows

Thinair for Windows is coming.

Thinair Cloud

You don’t need Thinair Cloud to start. Sign up with Google or an emailed link, with no password: your first sign-in makes your account. In the app, sign in from Thinair Settings ▸ Account.

Apps in Thinair Cloud are paid from prepaid credit, $0.10 per vCPU-hour while they are awake, and every new personal account gets a $10 starter credit for 30 days, with no card needed. Every app can run there, and they keep running while your computer sleeps. An organization needs Thinair Pro and pays for its Cloud apps from its own credit.

See plans and Cloud pricing.

Choose where each app runs.

Right-click empty canvas and pick the app, or pick it in the sidebar. Its Window opens at once, where you clicked, and asks Where and Who, the likely choice ready: press Enter, and only then does anything start. You pick the place each time you open an app:

• Your computer’s own name: the app runs straight on your computer, as you.
• ThinairOS: the app runs in a small, separate computer of its own inside yours, which never reaches your computer itself.
• Thinair Cloud: the app runs in the same small computer, on Thinair’s machines.

In ThinairOS, an app reaches only what its Profile holds: its sign-ins and keys, and the folders of Thinair Files it is given. Apps in the same Profile share those; nothing else crosses unless you allow it. Every computer starts with a Profile called Personal, whose home folder is /profile/personal.

• Use your computer or ThinairOS when the work belongs with your own computer and its files.
• Use Thinair Cloud when the work should keep running while your computer sleeps.

Start the agent you know.

There are two ways in. Each runs on your own Claude or ChatGPT subscription, and Thinair bills no model use.

A Terminal on your computer works on your own disk, as you do. The Agent works with the Thinair Files its Profile reaches: put what it needs in the Profile’s folders, or ask it to work in a Terminal in ThinairOS, where its commands then run.

Ask for something you can check.

Give the agent a clear outcome and a way to verify it. For an existing web repository, a first prompt could be:

The agent opens what it needs, a browser, a Terminal, a File, right beside its own Window and linked to it. Chrome runs in a small computer of its own, so a dev server on your computer shows there once you allow it: the agent asks, and a request over its Window lets Chrome in that Profile open the port. Choose Allow or Deny.

An agent can do anything inside its own Profile. To use an app in another Profile it asks first, the same way, and only your click lets it in.

Open what it made.

Read the changed files. Inspect the checks. Use the page in Chrome. The Windows the agent opened sit beside its own, so the result is something you can work with.

Move Windows by their title bars and arrange the canvas around the task. A Window is one app on your canvas; its bar shows where the app runs and its Profile.

Files in Thinair Files keep their versions, and the Trash keeps what you delete for 30 days. Save the sign-ins and keys an app needs in its Profile, and every app you open in that Profile has them.

A few names, made simple.

Workspace

The canvas where you arrange Windows and work in them.

Window

One app on the canvas: a Terminal, Chrome, the File Explorer, Preview, a Component, a Video or the Agent.

Place

Where an app runs, picked as you open it: straight on your computer, in ThinairOS, or in Thinair Cloud.

ThinairOS

The place that runs an app in a small, separate computer of its own inside this one, and what keeps those computers running in the background.

Profile

The wall around your secrets: the sign-ins and keys an app uses, and the folders of Thinair Files it reaches. You pick it as you open an app, and an agent acts as the Profile it runs in.

Thinair Files

Your files as Thinair keeps them, with versions and a Trash kept for 30 days. Each Profile reaches only the folders it is given.

Mode

Default or YOLO, set for each Profile in Thinair Settings ▸ Access. In YOLO, its agents may also use Thinair’s own tools, such as its workspaces and settings.

Thinair Cloud

Thinair’s own computers, where apps keep running while yours sleeps.
