Inklewriter is a program made for creating CYOAs, specifically e-CYOAs, quickly and simply. It has a very easy, intuitive format for the basic functions, as well as more complicated options for extras such as stats and randomized text. Inklewriter has been used to make e-CYOAs such as Frankenstien and Sorcery!, and it free to use.
