XINT/EXT is a messaging app modeled after the layout and typographic conventions of Hollywood screenplays.
Its most notable feature is having three types of messages — ACTION, DIALOGUE and SLUG — which enables any conversation (a.k.a. script) to become a rich narrative, fictional or not.
In addition, it’s possible to add characters if you need to write in voices other than your own.
The INT/EXT UI, based on the TypeCast design system, is also rather unique in the way it eschews everything but pure text.
