Book Writing Software
Scrivener is the most advanced (and most complex) word processor, designed for writers. It comes with all kinds of advanced features you won’t find in standard word processors.
Microsoft Word is the most commonly used word processor.(Does require a subscription and is one of the more expensive options).
Google Docs is a free alternative for writers on a budget who do not use MS Word. It works on any device, PC or Mac, and it automatically backs up your file inside Google Drive.
Evernote is the perfect tool for taking notes, organizing research, and much more (and it’s free!).
