I was fortunate to discover Scrivener pretty early in its existence, and in those many years, I’ve co authored one nonfiction book with it, and used it to write literally hundreds, maybe even thousands of nonfiction stories, from short news items to multi-thousand word works of narrative/dramatic nonfiction.
As pigfender explained well, the main value of Scrivener for me has always been the ability to write in chunks, to easily move those chunks around, and thereby to see how different structures work for any story I write. The way Scrivener turns the Binder into both an outliner and structure manager is its fundamental superpower, for my purposes at least. It makes it easy for me to just write down a bunch of ideas/points, flesh them out while keeping those details separate from the outline itself, and at any stage in the process, move them around until I’m happy with the structure.
In drafting stories, I also regularly use Document Notes (pasting relevant source material into the Notes area of each document I’m working on), annotations, typewriter scrolling, etc. etc.
Along with these advantages for writing itself, I value Scrivener’s info management — keeping source documents in a project. Of course I can use the Finder, or Files, for that, but somehow it’s easier to collect all source material inside the project.
I’m not qualified to understand why, but I also appreciate Scrivener’s functional design, which lends itself to relatively easy management and organization of large volumes of information that journalists like me collect. It just makes me feel good to start a project, import my source material, and have it all laid out there in front of me in a way that’s easy and even fun to work with. I’m sure some of the comfort comes from familiarity, but I’m also familiar with a lot of other apps that give me much less positive feelings when I open them!
Scrivener has greatly abetted my career as a journalist, and now I’m also using it to write plays. Along with email, browser, and maybe a few other basics, it’s the most valuable app I use, and I’m deeply grateful to Keith, the other developers and staff, and this community for making it happen.
