What you need

A computer with Windows 10 or 11 (x64), macOS (Apple silicon or Intel), or Linux x64. Autark is built and tested against an ordinary 8 GB RAM laptop; the heavy AI work happens at your AI provider unless you choose a local model.
At least one AI. A ChatGPT plan (used through OpenAI Codex), a paid Claude plan (used through Claude Code), an API key, or a local model server (Ollama, LM Studio, llama.cpp, vLLM). Claude Free cannot run agents.
An internet connection for your AI provider, for updates and for the local search model, which is downloaded the first time it is needed (about 135 MB).

Install on Windows

Download autark-windows-x64.exe. Your browser may warn that the file is not commonly downloaded; choose to keep it.
Start it. Windows shows a blue box, “Windows protected your PC”, with only a Don’t run button. Choose More info, then Run anyway.
Install. Keep “only for me”: no admin rights are needed. Pick a folder or keep the suggested one. A desktop shortcut is created.

If Run anyway is not offered: with Smart App Control turned on, Windows can block an unsigned installer outright, and there is no button to get past it. Turning Smart App Control off is a change to your whole PC and your decision. Read Microsoft’s note on it first, or use another PC.

Install on macOS

Download the DMG and open it. Drag the app into Applications.
Open it. macOS refuses the first time and says Apple could not check it for malware. Close that box with Done, not Move to Trash.
macOS 15 and newer: open System Settings → Privacy & Security, scroll down to Security, choose Open Anyway next to the app’s name and confirm with your password or Touch ID. macOS 14 and older: Control-click the app in Applications, choose Open, then Open again.
If macOS says the app “is damaged”, or still will not open it, the cause is the quarantine mark macOS puts on downloaded files. Check the file first (below), then remove the mark in Terminal:
xattr -dr com.apple.quarantine "/Applications/Autark.app"

That command tells macOS to stop treating this one app as an unchecked download. Nothing is repaired by it and nothing else on your Mac changes. Autark has no Apple Developer ID yet: the app is signed ad hoc and not notarized, so macOS offers no way around these steps. macOS may ask again for access to your keychain after an update, because every build carries its own ad hoc signature.

Install on Linux

Download autark-linux-x64.AppImage and make it executable: chmod +x autark-linux-x64.AppImage.
Run it. It needs FUSE 2, a working Chromium sandbox and a running system keyring. Without a keyring, secrets cannot be stored; there is no plain-text fallback.

The first start

Connect one AI. Sign in through the official tool of your provider; the app can install Codex or Claude Code for you and tests them with a real answer. Each added account lives in its own folder.
Type your name and company, and press Start.
Answer the first question. Your manager asks how far it may go on this PC.

Agents have full access from the first moment. The question is how you tell them what you want. It closes nothing technically. What that means

Check the file

Every release publishes SHA256SUMS.txt with the SHA-256 hash of each file. In PowerShell, in your Downloads folder:

Get-FileHash .\autark-windows-x64.exe -Algorithm SHA256

The hash must match the line for autark-windows-x64.exe in SHA256SUMS.txt. On macOS or Linux use shasum -a 256 <file>. A match shows the file arrived as published. It does not replace a signature.

Updates

Autark checks GitHub Releases every minute while the window is open and every 15 minutes from the tray. A small icon appears only when an update exists. On Windows and Linux one click downloads it, verifies it against the SHA-512 in the update manifest, installs it and restarts. Your agents, chats and settings stay where they are.

On macOS the app replaces itself where macOS allows it, and otherwise the icon leads to the download. A Mac with a version from before the rename gets this one once by hand: drag it over the old app in Applications; your data stays. That path is new and has not run on a real Mac yet.

Permanent links

Use these addresses to link to Autark from anywhere: in posts, docs or from the app itself. They always lead to the newest version, even if the release channel moves.

Uninstall

On Windows open Settings → Apps → Installed apps, find Autark and choose Uninstall. On macOS drag the app to the Trash. On Linux delete the AppImage. Your data stays until you delete the folders yourself: where they are. If you want to keep your company on another PC, use Back up in Settings › About first.
