Probably not. Unlike other apps, Byword doesn’t support any tools that are helpful for large projects like writing a novel. There’s no customizable glossary for terms, no optimization for phrasing, etc. You can categorize and save your work with basic file management, but that’s about it. The most Byword would be good for in this situation would be to write a chapter or section when you are on the go, then copy or export it to another writing app that you are using as the primary source of your novel. On the other hand, if you absolutely need zero distractions when you are writing, or you prefer to get as far away from the “computer” experience as possible and as close to writing on something like a typewriter, Byword may be your novel app of choice.
