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.

Chat and workflows aimed at go to market copy
Copy.ai moved away from short-form generation toward chained workflows, so the unit of work is a repeatable process rather than a one-off caption. Its chat tier reaches OpenAI, Anthropic and Gemini models from one subscription with unlimited words. Anybody who only wanted captions will find the tool has grown past them.
