Atticus vs Vellum Comparison 2026
Atticus writes and typesets a book in one application, bought once for $147 and running on Windows, Mac and Linux. Vellum only typesets: bring a finished manuscript and it produces ebook and print files that look professionally made, for $199.99 without paperback output or $249.99 with it, running on macOS only. Atticus is the cheaper, broader tool. Vellum is the narrower one that a Mac-only shop pays extra for because the output is worth it to them.

Atticus
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.

Vellum
Typeset a book that looks professionally made
Vellum does one thing: it turns a finished manuscript into ebook and print files that look like a publisher made them, with chapter headings, drop caps and ornaments that are already correct rather than waiting to be designed. Authors buy it the week they realise their own formatting looks amateur next to what is on the shelf. It runs on macOS only, which is a genuine barrier and the single most common reason people end up elsewhere.
Why people weigh these two
- Vellum instead of Atticus
- The typesetting half as its own product: professional-looking book layout for a one-time $199.99, against Atticus's $147 covering writing and formatting together.
- Atticus instead of Vellum
- Atticus both writes and typesets a book for a single $147 payment, about $53 less than Vellum, and covers the drafting stage that Vellum leaves out.
Which one should you pick
Atticus is for anybody on Windows or Linux, since Vellum simply does not run there, and for a Mac user who wants writing and formatting in the same $147 payment rather than two separate purchases. It covers unlimited books with no subscription, and updates come included rather than sold as new versions. The trade is that its typeset output is not the thing Vellum is known for.
Vellum is for an independent author on a Mac who has finished writing and wants a book that looks like a publisher made it, with chapter headings, drop caps and ornaments already correct. Vellum Press is $249.99 and is the one to buy unless you are certain you will never need paperback output, since the $50 saved on Ebooks costs more later if you upgrade. The price only makes sense amortised across more than one title, and it is simply unavailable if you are not on a Mac.
Common questions
- Why does Vellum cost more than Atticus?
- Vellum charges $199.99 for ebook output or $249.99 with paperback included, against $147 for Atticus, which covers both writing and formatting. Vellum only formats; it assumes the manuscript already exists and is focused on making the typeset output look professionally made.
- Can Vellum run on Windows?
- No, Vellum is macOS only. Atticus runs on Windows, Mac and Linux, and in a browser, which is the main reason Windows and Linux authors choose it by default.
- Does either one help with writing the manuscript itself?
- Only Atticus. It is a writing app as well as a formatter. Vellum assumes a finished manuscript arrives and turns it into ebook and print files; it has no drafting tools of its own.
- Which is cheaper for someone publishing several books?
- Atticus, at $147 for unlimited titles with no per-book fee. Vellum's $199.99 or $249.99 also covers unlimited books as a one-time payment, but it starts higher, so the dollar gap in Atticus' favour never closes, even as the cost per book falls on both sides.
