yWriter is a word processor which breaks your novel into chapters and scenes, helping you keep track of your work while leaving your mind free to create. It will not write your novel for you, suggest plot ideas or perform creative tasks of any kind. yWriter was designed by an author, not a salesman!

Scrivener is a word processor and project management tool that stays with you from that first, unformed idea all the way through to the final draft. Outline and structure your ideas, take notes, view research alongside your writing and compose the constituent pieces of your text in isolation or in context. Scrivener won't tell you how to write—it just makes all the tools you have scattered around your desk available in one application.
