Install the app

  1. Open the .dmg file in your Downloads folder.
  2. Drag the app onto the Applications folder in the window that opens.
  3. Open the app from Applications. If your Mac asks you to confirm, click Open.

The app has no dock icon. Look for the brain icon in the menu bar at the top of your screen.

  1. Open the installer in your Downloads folder.
  2. Windows may show a blue box that says Windows protected your PC. This is normal for a new app. Click More info, then Run anyway.
  3. Look for the brain icon near the clock. You may need to click the small arrow to see it.

If nothing happens when you open the installer, right-click the file and choose Properties. Tick Unblock, click OK and open it again. If your browser says the file is not commonly downloaded, click the three dots next to it and choose Keep. Not sure about any of this? Ask the person who sent your invite before you continue.

Start working

Open the Claude desktop app and choose the Code tab. Open your brain folder and ask: What can you do in this brain?

Your brain does not run in the Chat tab. If Claude cannot see your files, check that you are in the Code tab.
