A Vellum alternative that runs in the browser
Vellum is excellent — and $249, Mac-only, and another app to learn. The alternative: upload the manuscript, download the book.
Vellum earns its reputation: beautiful output, polished app, the standard against which everything else is measured. The costs are structural, though — $249.99 for print+ebook, macOS only, and a workflow where your book lives inside another application. The listicle answer is 'buy Atticus instead' ($147, still an app to learn). Ceeryo's answer is different in kind: no app at all. Upload the .docx you already have, choose one of three designed interiors and a trim, and download a print-ready PDF (KDP geometry verified, gutter from your real page count) plus EPUB — priced per book, so a one-book author doesn't fund an app license. Fair trade-offs, stated plainly: Vellum offers more interior styles and box-set tooling; Ceeryo offers zero learning curve, any operating system, and typography verified by preflight rather than by eye.

How it works
How to a vellum alternative that runs in the browser in four steps
The fastest way to a vellum alternative that runs in the browser without manual copy-paste, screenshots, or formatting cleanup.
- Step 1
Upload your manuscript
Drop in the .docx manuscript you have finished writing. Your file is processed only to typeset it and is never used to train models.
- Step 2
Chapters are detected
Chapter openings, scene breaks and italics are found automatically, without changing a word of your text.
- Step 3
The book is typeset
Trim size, margins and gutter, running heads, drop caps and chapter openers are set as a real book interior.
- Step 4
Download print PDF + EPUB
A print-ready interior PDF at your chosen trim size plus a clean EPUB, checked against the geometry KDP enforces.
In short
Ceeryo is a browser-based Vellum alternative: upload a Word manuscript, get a print-ready PDF plus EPUB with KDP's geometry checks shown passing — on Windows, Mac or Linux, priced per book instead of a $249 Mac-only license. Vellum still wins for box sets and maximal style control; Ceeryo wins on zero install, zero learning curve and per-book cost.
What is the best alternative to Vellum?
Depends on what constrained you. If it was the Mac requirement or the $249 license: Ceeryo typesets in the browser per-book from your Word file, with KDP preflight included. If you want another installable app with deep manual control, Atticus ($147, cross-platform) is the usual pick. For free basic output, Reedsy Studio and Kindle Create exist with standardized results.
Different in kind
Not another app — the absence of one
Every 'Vellum alternative' list compares apps. The structural alternative is server-side typesetting: nothing to install or update, the same workflow on any machine, output verified by automated preflight rather than eyeballing, and pricing attached to books rather than software.
- Works on Windows/Mac/Linux/Chromebook identically
- Takes the .docx you already have — no import/migration
- KDP preflight: trim, page range, gutter bracket, fonts — shown passing
- Per-book pricing; a one-book author pays for one book

Vellum for Windows
Vellum doesn't run on Windows — and the usual answer is buying different desktop software. The browser needs no port.
formatterAn Atticus alternative for finished manuscripts
Atticus wants to be where you write. If your book is already written in Word, you need a typesetter — not a second home for your text.
formatterConvert Word to EPUB — Properly
Not a file-format shove: chapter detection, a real navigation TOC, preserved italics, and valid EPUB3 structure from your .docx.
formatterFormat Your Romance Novel
The Colette theme: elegant chapter numerals between hairlines, a warm readable serif, and ornamented scene breaks — made for romance.
formatterKDP margin checker
Every margin calculator repeats Amazon's table. The question that gets books rejected is whether your PDF actually meets it.
formatterWord count to book pages — measured, not estimated
Most words-per-page tables are guesses. These numbers come from actually typesetting manuscripts at each trim size.

Frequently asked questions
Is the output as good as Vellum's?+
For text-led fiction and memoir the typographic fundamentals — trim-exact pages, correct gutters, drop caps, running heads, embedded fonts — match what Vellum produces, and preflight verifies them mechanically. Vellum still offers more style variety and specialty tooling like box sets.
Can I import my Vellum project?+
Upload the manuscript as .docx — Ceeryo works from the document, not from Vellum's project format. Export your text from Vellum to Word first.
What does it cost?+
Per book rather than per license — see pricing. The typeset preview and full preflight are shown before any payment.
