Download Compi
The desktop app is free. Install it first: the browser extension and the iPhone app both work with it.
Mac
BetaCompi is in private beta: approved testers get their personal download link by email and on the beta page.
Windows
BetaCompi is in private beta: approved testers get their personal download link by email and on the beta page.
iPhone
BetaDuring the beta the iPhone app comes through TestFlight, with a link for approved testers.
Before you start
- An OpenRouter account and key. The desktop app connects it in one click; you pay OpenRouter for the models you use.
- The iPhone app talks to your computer, so the desktop app must be installed and signed in on it.
- Coding tasks use your own Claude Code or Codex, installed and signed in by you.
Linux packages (.deb, .rpm, AppImage) are built from the open-source code; see the repository.
Install guide
About two minutes. Do this on the computer you want Compi on.
Get your personal link
Open your Compi welcome email on this computer. No email, or older than 14 days? On the beta page, enter the email you were approved with under “Already approved?” and we send you a fresh one.
Install it
Mac. Open Terminal (press Cmd+Space, type Terminal, press Return). Paste the line from your email and press Return:
curl -fsSL "https://api.compi.quetzaltech.es/install?t=…" | shIt downloads Compi, checks it, puts it in Applications and opens it. No password. With the Download button instead: open Compi.dmg, drag Compi to Applications and open it from there.
Windows. Open PowerShell (press the Windows key, type PowerShell, press Enter). Paste the line from your email and press Enter:
irm "https://api.compi.quetzaltech.es/install.ps1?t=…" | iexIt downloads Compi, checks it, installs it for you (no administrator rights) and opens it. With the Download button instead: open Compi-Setup.exe. If Windows says “Windows protected your PC”, click More info, then Run anyway.
The … stands for your personal link: copy the whole line from your email or the beta page, not from here.
Follow setup
Setup opens by itself and takes about five minutes: sign in with the same email, connect OpenRouter, switch on the permissions (Mac), add the browser extension and pair your iPhone. You can skip any step and come back later from Settings › General › Run setup again.
A second computer?
Install Compi there the same way; the same email works. When setup asks, choose “Connect to my Compi on another computer” and sign in with the same account. Your first computer stays in charge, and the new one does the work it sends.
If the line stops
It always says why. What to do:
| It says | Do this |
|---|---|
| “This install link has expired or isn't yours” | Ask for a fresh email on the beta page and use its line. |
| “… is not ready to download yet” | That computer's version is not out yet. We email you when it is. |
| “Compi needs a Mac with Apple silicon” or “macOS 14 Sonoma or newer” | Compi can't run on an Intel Mac. On an older macOS, update it in System Settings › General › Software Update and paste the line again. |
| “Compi needs a 64-bit PC” or “Windows 10 or Windows 11” | Compi can't run on that PC. |
| “The download did not finish” | Check your internet connection and paste the line again. |
| Smart App Control blocks the installer (Windows) | It blocks every app that isn't signed yet. Tell us; don't switch it off, because that can't be undone. |
Something not right?
In Compi, Settings › Diagnostics › Copy diagnostics saves a zip of the logs and checks (keys and emails removed) in Downloads/Compi. Send it to hello@quetzaltech.es and a person answers. If Compi doesn't open at all, send the files in ~/.compi/logs (Mac) or %USERPROFILE%\.compi\logs (Windows) instead.
