Depending on what type of book you plan on writing (fiction, non-fiction, ...) you get certain layout options that give you a guideline during the writing process. You can brainstorm ideas and attach them to the respective chapters and keep growing the ideas.

It makes the process flow more easily, and it can be used for plotting as well as writing the actual book. It's great for tracking daily word counts, as well as setting daily/project word goals. Broad adoption in many countries and active support community.

This software is so flexible and customizable! It is also easy to use once you get the basics down, and it can be adjusted to suit any work style. My favorite thing is how organized it allows me to be, and - with five projects going at one time, all in different stages - organization is a must! All of the information you type up is also EASILY compiled; whether you need a complete manuscript, just the comments, notes, or research, you can get all of it converted into various formats. It also automatically backs up all of your work and even allows you to save your work in various stages, so if you need to reference an old version, it's not gone completely, but it also doesn't get in the way of the new. I also love the compiling feature, which allows you to easily and quickly format your manuscript for publishing.
