Scrivener is a word processing program that allows users to organize drafts and manuscripts into chapters and sections, manage research notes, and import documents such as PDFs and Word documents. It also has a corkboard feature for organizing notes on "index cards" visually, and a full-screen writing mode that blocks out other windows to allow the user to concentrate on writing.
