For fellow writers …

I began using Scrivener when I first decided to switch to fiction. I find it extremely useful. It has helped me be more organized, zero in on my characters, and see what a published chapter would look like, among many other features.

Here is a definition I found online that gives you a good idea of its features:

Scrivener is a software application created by Literature and Latte and used by many writers. It provides a wide range of features to help writers organize their material, do research, create plots and outlines and much more.
