gInk is an Open Source on-screen annotation app designed to allow you to make notes on a screen display.

gInk can help improve presentations and demonstrations and contribute to work on fleeting thoughts or ideas that need to be recorded beside something on your screen.

The features provided in gInk are inspired by another screen annotation software Epic Pen but with an emphasis on more ease of use.

gInk's interface is designed to be as simple as possible without distracting attention from the presentation. Unlike other similar software, you are given a selection of pens to draw things instead of changing individual settings of color, transparency, and tip width every time you make a notation. Each pen combines these attributes and is configurable to your specific needs.
