Vellum or LiberScript for Mac and Windows Authors

The Answer in Brief

If you own a Mac and your main goal is a beautifully typeset book with as little effort as possible, Vellum is a proven choice. If you use Windows, switch between computers, or want drafting, editorial feedback and formatting in one place, LiberScript covers more of the journey from manuscript to published files.

Both produce professional files for Amazon and other stores. They differ in how much of the process they try to handle, where they run and how you pay.

Two Different Philosophies

Vellum focuses on one job and does it with great polish. You write elsewhere, usually in a word processor, then bring the finished manuscript into Vellum to style it. Its styles change chapter openings, drop caps, ornaments and fonts together, so the book looks consistent and refined.

LiberScript tries to replace several tools at once. It is a browser workspace where you can draft or import a manuscript, run a critique across the whole book, plan word-count goals, design the interior and export every file. The idea is to stop juggling a word processor, a formatter and a separate editing app.

Neither approach is better in general. It depends on whether you already have a writing setup you love, or would rather work in one place from first draft to final file.

Feature Comparison

Mac, Windows or Anywhere

Platform settles the question for many authors. Vellum only runs on a Mac with macOS 13 or newer, so Windows users would need to buy or rent a Mac to use it.

LiberScript runs in a web browser, so it works on Windows, Mac, Linux and Chromebook, and you can pick up where you left off on any computer. The trade-off is that it is an online tool rather than a desktop app, so you need a connection to work in it.

How the Finished Book Looks

Vellum's reputation rests on the look of its books. Its styles are carefully designed, and it is hard to produce an amateurish interior with it. If typography is your top priority and you are happy with a curated set of choices, it is difficult to beat.

LiberScript gives you more individual settings to adjust: fonts, sizes, line spacing, chapter opener styles, drop caps, epigraph formatting, chapter numbering and whether chapters start on a new right-hand page. Its preview shows your book as real paginated spreads at your trim size, with running headers and page numbers, and you can switch between print and ebook views to check both.

Beyond Formatting

This is where LiberScript adds the most. Its critique reads the full manuscript and points out overused adverbs, passive voice, filler words, clichés, repeated phrases, show-versus-tell moments and pacing issues, each linked to the exact sentence. A grammar and spelling check runs alongside, and a readiness score lets you measure progress between drafts.

It also includes a Plan tab with a word-count goal, a calculated daily pace and an ordered list of story beats, plus automatic footnote numbering and a generated bibliography for nonfiction. Co-authors and editors can work in the same project.

Vellum deliberately stays out of writing and editing. Its strength is that what it does, it does exceptionally well, and it adds features authors of series value, such as box sets that combine several books into one ebook.

Bringing In an Existing Manuscript

Most authors arrive with a draft already written. Vellum imports Word documents, and it works best when your chapters use consistent heading styles so it can split the book correctly.

LiberScript accepts DOCX, EPUB, PDF, Markdown and plain text, and it looks for the book's real structure as it imports: title page, copyright page, dedication, prologue, chapters, epilogue and back matter each become their own section. Bold and italic text is kept rather than flattened. That makes it useful if your manuscript exists as an old EPUB or a PDF rather than a tidy Word file.

A Finishing Week in Each Tool

Picture the last week before you publish. In Vellum, you import the final Word file on Monday, pick a style, fix any chapter breaks, add front and back matter, and by midweek you are previewing the ebook and print layout. You buy the license, export, and order a printed proof.

In LiberScript, you might import the same file on Monday, run the critique to catch a last round of repeated phrases and filler words, fix them in the editor, then move to the Design tab to choose a theme and trim size. You export the EPUB and print PDF from the same project and order a proof. A Week pass covers the whole job.

Either week ends with professional files. The difference is whether that week also included a final editorial sweep inside the same tool.

Cost Over One Book and Over Many

For a single book, LiberScript's passes cost far less. Over many years, Vellum's one-time price and LiberScript's Lifetime pass land in a similar range, so the decision rests on features and platform rather than money.

Limits to Keep in Mind

• Vellum is Mac only, requires Vellum Press for paperbacks, and does not help with drafting or editing.
• LiberScript works online in a browser, sells time rather than a permanent license unless you choose Lifetime, and is gradually rolling out features such as its cover studio, so not every account has them yet.
• Both format the interior only. Covers, editing by a professional and uploading to stores are separate steps.
