⚡ ChromeBoost Desktop · Mac and Windows

Download ChromeBoost.

ChromeBoost Desktop is a Mac and Windows app that does jobs in your own Chrome browser: you type what you want in plain English and it clicks, reads and types for you, with no terminal involved. It needs Google Chrome and the ChromeBoost extension from the Chrome Web Store, and it walks you through adding the extension the first time you open it.

You sign in with your own Claude account, through Anthropic's own window. ChromeBoost never sees your password.

01 / Mac

Opening it the first time on a Mac

ChromeBoost is not yet registered with Apple's notarization service, so the first time you open it macOS shows a warning and will not open the app until you say otherwise. The warning is about that missing registration, not about anything the app does, and the steps below clear it in about a minute.

These steps match macOS 15 and macOS 26. On macOS 13 and 14 the first dialog offers Cancel instead of Done, but everything else is the same.

1

Drag it into Applications

Open the downloaded ChromeBoost.dmg and drag ChromeBoost into Applications.

2

Open it once, then click Done

Open ChromeBoost from Applications. macOS says "Apple could not verify ChromeBoost is free of malware". Click Done, not Move to Trash.

3

Open System Settings

Open System Settings, then Privacy & Security.

4

Click Open Anyway

Scroll down to the Security section. You will see a line saying ChromeBoost was blocked. Click Open Anyway.

5

Confirm with your password

Click Open Anyway again in the confirmation, then enter your Mac password.

6

ChromeBoost opens

That is it. You only do this once.

If the Open Anyway button is missing. The Open Anyway button disappears after about an hour. If it is gone, open ChromeBoost from Applications again and return to step 3.
Comfortable with Terminal?

One command does the same job as steps 2 to 5. It removes the download flag macOS puts on files from the internet, so the warning does not appear at all.

Run it after you have dragged ChromeBoost into Applications, then open the app as normal.

02 / Windows

Opening it the first time on Windows

ChromeBoost is not yet signed with a Windows certificate, so Windows shows a SmartScreen warning the first time you run the installer. It is the same warning every new program gets before enough people have installed it, and it takes two clicks to get past.

1

Run the installer

Run ChromeBoost-windows-setup.exe from your Downloads folder.

2

Click More info

Windows shows "Windows protected your PC". Click More info.

3

Click Run anyway

A Run anyway button appears at the bottom. Click it.

4

Follow the installer

Follow the installer. You will not see the warning again for this version.

The warning fades on its own. SmartScreen shows it for any new program until enough people have installed it. As more people install ChromeBoost, later versions may skip it entirely.
03 / Updating

Updating

ChromeBoost checks for new versions when it starts. When one is ready it shows a Get it link that brings you back to this page.

On a Mac, download the new copy and drag it into Applications over the old one. On Windows, run the new installer. Your jobs and settings are kept.

On a Mac the warning may come back. Each download is a fresh file, so macOS can show the first-open warning again after an update. The steps above clear it the same way.
04 / Privacy

Privacy in one paragraph

ChromeBoost Desktop talks to three things and nothing else. It talks to your own Chrome, through the ChromeBoost extension on your computer. It talks to Claude, through your own Claude account, which is where your instructions and the pages it reads for you are sent. And it talks to Polar, the service that handles licences, to check that yours is valid. It does not collect analytics on what you browse or what your jobs do. The full details are in the privacy policy and the terms of use.
