I live in Scrivener by Literature and Latte. I have used this app for over 12 years. It is an excellent writing app with versions for Microsoft Windows, macOS and iOS. Unlike a word processor, Scrivener is a writing environment. Literature and Latte designed it from the ground up for large documents. If you’re writing novels, this is the app for you. It is hands down the most advanced writing environment you’ll ever use. There is a bit of a learning curve, but there are plenty of resources available to help you through it. With Scrivener you can create outlines, use a cork board, character sketches, keep research documents, make annotations, and track changes. The list goes on and on and on. I’ve found that having all the information you need to complete your work readily available without having to leave the writing environment is an invaluable feature. The user interface is easy to understand and well designed. Just about every aspect is customizable.
When it’s time to publish, it has built-in templates for properly formatting paperback, hardcover, and ebooks. Of course, there are options for you to override default settings and tweak to your needs. There are also options for exporting your document to .pdf, rich text, MS Word, OpenOffice, and Multi-markdown to name a few. It keeps your work safe by making automated backups to a folder and intervals of your choosing. The pricing model is a onetime purchase as opposed to the subscription model that so many companies have gone to. The cost, 49.00 for the Windows and Mac versions, and 19.00 for the iOS version. You simply can’t go wrong with this app.
I didn’t point to a video because there are so many available. This is the most documented writing app on the market. Browse the Literature and Latte website or YouTube for a plethora of training videos highlighting the many, many incredible things about Scrivener.
