WorkFlowy allows you to store dramatically more information than other tools, while keeping it organized. You can create infinitely nested bullet points, in any structure you like, as deep as you like. Simple, but powerful.
Fluidly switch from looking at the entire forest to looking at a particular tree. The ability to zoom in on any bullet, and control what's visible under it, lets you see only what you need to see at a given moment.
Share a whole document with your team, or just a small part of that document with someone external. This is the most flexible sharing model of any tool on the market.
