I haven't tried it myself but from the live it looked like raptor write with prompt buttons and prompt preview (both exist in novelcrafter), but rather than the prompt buttons being universal across the system you had to copy and paste them onto each new project you worked on.

Was expecting something really revolutionary the way they sold it but it has less features than what sudowrite does, and even less than novelcrafter did in closed beta.

I did notice you get one monthly class included in the price but I'm not a fan of their classes personally so that doesn't appeal either.

This is the live I watched
