It wasn't immediately apparent based on the landing page, that I would be able to export my finished novel, or that you provide some sort of security for my work (syncing, backups with Dropbox, Google Drive, maybe?). I think those will be people's two biggest questions or apprehensions.

I kind of hate the scrolljacking. It's too flashy. It's sluggish. It is kind of distracting. I think the small gif of the kanban is much more effective, and the rest of the copy is too.

Maybe a bit of top padding on the 'CenterCallout' where you say "Writing is just one click away" and "A new way to note".

You might want to sprinkle one or two more calls to action for purchase or trial in between some of the feature descriptions.

Otherwise, the kanban setup for chapters and such seems really intuitive and I'm surprised I haven't seen that before in this context. I'd definitely be interested in giving it a shot. Maybe paying the $8 will encourage me to write more. I'll bookmark it to check out after work!
