The Epic Pen is a small application used to draw directly on the desktop of the operating system or in various applications within the operating system. The tool runs in the window and has a minimalist interface, which includes access to the most needed options. The user can draw lines of different thicknesses in 16 different colours and quickly remove unnecessary markings at the touch of a button.

The Epic Pen also includes a screenshot function that can be saved in PNG format anywhere on your computer's hard drive.
