Canvas looks strikingly similar to this (almost exactly the same aesthetically), and I'm curious what the "killer feature(s)" are which give it an advantage over Paper, which is developed by a much larger company (Dropbox).
Came here to say the same thing. Extremely similar to Dropbox Paper.
I haven't been that happy with Dropbox Paper though. It doesn't handle basic things like bullets in indented blocks, or line/paragraph breaks in numbered lists. Hackpad (Dropbox acquisition) didn't look as nice, but had more functionality. Now Paper is replacing Hackpad.
Is Dropbox Paper planning integrations with third parties? I can already do basic collaborative editing in Google Docs, and it sounds like Paper is similar to that. The killer feature for me (when shipped) is being able to drop in native representations from the other tools I used heavily (Slack, Trello, GitHub, etc) into a document that I'm collaborating on.
For example, right now in a Google Doc if I want to connect it to a Trello list I need to add a bullet for each card in the list, make it a link to the card, and keep both things in sync. What if I could just drop in the whole list (or even a whole board in some cases) and have my project plan and my specific cards in the same context without jumping between different tools? That's a killer feature for me if they can pull it off.

I'll be giving Canvas a try.
