Author Sweets, by the kind of book
One app, four pages that explain it in the terms of the book you are writing. Everything on them is in every book; the pages only say which parts matter first.
Author Sweets for novelists
A novel is long enough to get lost in. Author Sweets keeps the shape of the book in view while you write the scenes, and stays out of the way of the writing.
Author Sweets for memoir writers
A memoir is made of scenes from a life, and the hard part is choosing and arranging them. Author Sweets gives those scenes a place, keeps the people and places straight, and keeps the draft yours.
Author Sweets for nonfiction authors
A nonfiction book is an argument carried over chapters, with the research close at hand. Author Sweets keeps the notes a click from the draft and the deadline in view.
Author Sweets for writers with beta readers
A beta round is a lot of email: the file, the version, the questions, the chasing. Author Sweets runs it from the book. Readers open a link; you see what they said and how far they got.
Writing something else? The home page lists everything the app does, the guides cover the craft, and the comparison sets it beside the other tools.
