Write and typeset a book for one payment
Atticus is a writing app and a book formatter in one, which is the pairing self-published authors otherwise buy twice. It runs in a browser and offline, so a manuscript is not stranded by a bad connection, and it exports files the retailers accept. One payment covers unlimited books and there is no subscription behind it.
Our note
The comparison people actually make is against Vellum, which costs more and is Mac only. If you are on Windows this is the answer by default; on a Mac the question is whether Vellum's output is worth roughly twice the money to you.
Only on this side
Style and grammar checks for long drafts
ProWritingAid reports on a whole manuscript rather than a sentence, with checks for pacing, repeated phrasing, sticky sentences and dialogue tags that Grammarly does not attempt. The reports take a while to read and are worth it once. Free accounts are limited to 500 words at a time, which rules out the long-document work the tool is best at.
Ratings are the average of reviews readers left. The facts are stated by each tool’s own listing and are not verified by CloutStack. How we make money.
