From the developer:
ShadeIt dims your screen even more than current monitor settings allow. This is most interesting at night when you want to work without room lights switched on.
ShadeIt supports multiple monitors and spaces.
Adjust the brightness in the Status menu or use the (user-defined) hot keys.
In the preferences, you can assign the hot keys and define whether ShadeIt should be launched when you log in to your computer.
