A Mac app for authors who publish. What you see while you write is exactly what the printer gets.
Free 14-day trial, no card needed. macOS 12 or later, Apple silicon and Intel.
Same font, same margins, same page breaks as the finished book.
Write, design, proof, cover and export, from the first sentence to the files the printer and the stores ask for. You never leave the page.
Chapters flow onto pages as you type. Chapter openers, running heads, page numbers, drop caps, widows and orphans are handled the way a typesetter would.
Focus mode slides the panels away and leaves only the paragraph you are writing fully inked. The rest of the page is still there, just quieter.
Save a version of a chapter whenever it feels right. Compare any two word by word, restore one, or go back to the copy Manutius saved on its own before Claude rewrote a chapter.
Highlight a passage and leave a comment. They sit in the margin while you write, travel with the Word manuscript for your editor, and never appear in the PDF or the EPUB.
Every choice a book designer makes is a setting, applied to every page at once, shown to you before the printer ever sees it.
Pick a typeface, size and line spacing, choose the trim, and watch the pages reflow. A large-print edition is one click.
Six chapter-heading styles and six scene-break ornaments, applied to the whole book at once and carried into the PDF and the EPUB. Notes can sit at the bottom of the page they belong to.
Half title, title page, copyright, dedication, contents, parts, “Also by”, about the author, endnotes. Tick the box and the pages appear where they belong, on the right-hand side, with the page count updated.
Manutius follows your Mac, or you choose. Dark chrome with paper pages for late drafts, or go all the way with dark pages. The print PDF stays black on white.
The print PDF, the ebook, the manuscript for your editor and the cover, paperback or hardcover, all come out of the file you were just writing in.
Add your front art. Manutius computes the spine from your page count and paper, builds the back with blurb and barcode area, and exports a full-wrap print PDF plus a store JPG.
Spelling, grammar and style underlines in American, British, Canadian or Australian English, all on your Mac. Then let a natural voice read from the cursor and highlight each sentence as it goes.
Every plan includes everything in Manutius and works on up to three Macs. Try it free for 14 days first.
Prices in USD. Secure checkout by Stripe. Lost your key? Recover it by email.
Manutius becomes read-only: you can still open every book, read it and copy your text out, but not edit or export until you buy. Your files are always yours. They are plain .book files on your Mac.
Yes. Writing, proofing, export and covers all run on your Mac. The voice for Listen is downloaded once (about 95 MB) and then works offline. The app checks in with manutius.app occasionally to confirm a license and look for updates.
macOS 12 Monterey or later. There are separate downloads for Apple silicon and Intel.
It is the same layout you see on screen, at exact trim size with fonts embedded and bleed-free interior pages, which is what KDP and IngramSpark ask for. The status bar warns you if your inside margin is too small for your page count.
No. Assist is optional and works with any app that speaks MCP; chatting inside Manutius needs Claude Code installed with your own account. Everything else works without them.
If Manutius isn’t for you, email hello@manutius.app within 14 days of buying and we’ll refund you.
