Atticus combines a manuscript editor and a book formatter, so an author can draft, style and export without moving files between apps. It is built as a Progressive Web App, which means it runs in a browser or as an installed app on Windows, Mac, Linux and Chromebook, and the vendor says it keeps working offline while backing up to the cloud. Formatting starts with 17 templates that Atticus says give more than 1,200 combinations, and a custom theme builder covers authors who want their own chapter headings. A previewer shows how pages look on phones, tablets, Kindle, Kobo and Nook readers before you export EPUB, print-ready PDF or DOCX. The price is $147 once, with ongoing updates and a 30-day money-back guarantee. The trade-offs are small but real: there is no MOBI export, the template library is smaller than Vellum's, and version control is listed as coming soon. For authors who do not own a Mac, it is the most complete paid formatter here.
