Scrivener (software) - Wikipedia, the free encyclopedia
Scrivener is a word-processing program designed for writers. Scrivener provides a management system for documents, notes and metadata. This allows the user to keep track of notes, concepts, research and whole documents for reference (documents including text, images, PDF, audio, video, web pages, etc.). After writing a piece of text the user may export it to a full-fledged word processor for formatting.
