Chatterbox is a GameMaker narrative design tool. It is loosely based on version 2 of the YarnScript language, used in games such as Far From Noise and Night In The Woods. Chatterbox itself has been used in many projects: Notice Me Leena-senpai!, Love Garden, Horizonite, Schrodinger's Catgirl and Demon Hearts to mention but a few.
Chatterbox uses a custom scripting language called "ChatterScript" that is both convenient for writing complex branching dialogue and accessible for people who are less confident when programming.
ChatterScript files can be written by hand, but the best way to start with ChatterScript is to use an editor. The best editor to use Crochet, available on Windows, MacOS, & Ubuntu, or as a web-based editor.
