Clutter Cloak is a free desktop dimmer which you can use in order to quickly, using keyboard shortcuts, decrease the brightness of certain sections of the screen and only focus on the window of the application that you are using. Either entire application windows, or only certain sections of them can be dimmed down. Clutter Cloak will automatically detect only important parts of windows, like for example when using a text editor, only the text area where text is actually typed is dimmed.

Next to turning down the brightness of the desktop and focusing on application windows automatically, like what we did on the image above, two other ways of how you can dim down the desktop are available.

Each one of the three screen dimmers that we mentioned have its own hotkeys.

Photo uses color comparison to detect edges of for example images, and videos on websites to only focus on them, while the last, Blind mode, dims down the brightness of the entire screen. Key features of Clutter Cloak are:

  • Free and easy to use – very simple install
  • Allows you to turn down the brightness of windows, areas or entire screen
  • Opacity of the cloak is adjustable with the help of percentage points
  • Optional multi monitor support – dims down everything on all monitors

While hitting the default Shift+Alt+F11 for dimming down the selection around images, red selection rectangle will pop-up. This type of photo selection isn’t very precise, so be patient. How a dimmed section of the window looks like can be seen on the first image above. Fullscreen brightness change means that the entire screen will be changed to the pre-configured values in settings. Don’t worry if you turn your entire screen black, you just need to click to return everything back to the way it was.


Clutter Cloak will help anyone who’s having problems with keeping focus on whatever application that you need to use. Dimming everything down, all the way to total blackness, will surely help you tone out any distractions that might be present on your screen. If you don’t want to use completely black screens, simply adjust the opacity, among other options.
