I am using Articy:Draft, mostly to organise my images, dialogs and keep track of my flow. It's good to see everything in one place, but I actually cannot imagine how exporting stuff would be useful to implement in C2. Maybe an external dialogue file?
I found it more useful than juggling through word/excel/illustrator, yet the software is a bit sluggish at times on my side (my graphic card is kinda old).
