When you're done, compile your project into a single document, and export in formats like DOC, rich text, PDF, ePub, Kindle, and even export for other apps like Final Draft. It's actually hard to encapsulate just how many options Scrivener gives you. And each part of the app can be customized to create the exact writing environment that you need. Keep your work segmented for easier organization and edition, while maintaining its structure with the Binder. Import images, PDF and other media you've used as research to refer to it later. Organize your ideas on digital notecards and lay them out on the corkboard to see how your work fits together. Novels, scripts, essays, research papers, it doesn't matter, because Scrivener supports all of them.
Scrivener is nothing short of a full-featured suite of tools for writers.
