What is CoAuthor?
CoAuthor is an AI platform for producing books intended for self-publishing, covering research, writing, design and packaging in one guided process of fourteen steps grouped into three phases. It begins with market analysis: the tool examines existing titles in a niche on Amazon, including competitor data, and suggests a title, an author persona and an outline. Writing then proceeds one section at a time, and inline agents can expand, tighten or add sources to any highlighted passage. For packaging, CoAuthor generates a cover that fits the genre, a book description, a formatted manuscript and optional extras such as A+ content, trailers and video ads. An Image Studio and Page Designer extend it to illustrated storybooks, colouring books, puzzle books, planners and journals. The site states that the product is in beta and that the user approves each step.
