    Use case fit

    Where each tool actually wins

    Vellum is the gold-standard book formatting tool for indie authors on Mac — a polished, one-time-purchase desktop app that turns a finished manuscript into publish-ready EPUB and print PDF with professional typography. GETebook.ai is the other half of that equation: an AI-powered drafting and generation tool that handles the writing and cover, not the final formatting polish. Many serious self-publishers use both.

    Where Vellum wins

    • Best-in-class ebook and print formatting. Vellum's style presets, drop caps, ornamental breaks, and chapter openers are genuinely the best of any indie tool. The resulting EPUBs pass Amazon KDP and Apple Books QA cleanly, and the print PDFs rival traditional publishers.
    • One-time purchase. $199 (ebooks only) or $249 (ebooks + print) paid once. For authors publishing 5–10 books a year for the next decade, the economics beat any subscription tool.
    • Offline Mac-native desktop app. Runs locally on macOS. No login, no cloud, no subscription renewal anxiety. For authors who distrust cloud-locked workflows, Vellum is a durable tool.
    • Industry-standard in indie publishing. The vast majority of successful indie authors use Vellum for final formatting. It's the de facto standard in the 6-figure indie author community.

    Where GETebook.ai wins

    • AI drafting — the whole point. Vellum doesn't write. It takes your finished manuscript and formats it beautifully. If you don't have a manuscript yet, Vellum can't help you. GETebook.ai generates the manuscript from a concept across six formats.
    • Six dedicated eBook formats. Vellum's formatting presets are optimized for fiction novels and non-fiction trade books. It doesn't have purpose-built lead magnet, workbook, or course companion formats with the appropriate structure (CTAs, fillable exercises, funnel scaffolding).
    • Cover design generation. Vellum has basic cover tooling (ebook-only covers using built-in templates). It doesn't design print covers. GETebook.ai generates KDP-compliant covers with typography for any format.
    • Cross-platform. Vellum is Mac-only. If you're on Windows or Linux, Vellum isn't an option at all. GETebook.ai runs in any browser.
    • Bundled drafting + cover + export. Vellum is the finishing step in a workflow that usually costs $600–$1,200 to assemble (writing, editing, cover design). GETebook.ai replaces the drafting and cover portions of that pipeline for $29–$99/month.
    Summary

    The honest take

    These tools aren't really competing — they're complementary. Vellum is the best formatting tool on the market for indie authors who already have a manuscript and want professional polish. GETebook.ai is an AI-powered generation tool that handles the drafting and cover, but its final export is capable-not-gorgeous compared to what Vellum produces.

    Common professional stack: draft the book in GETebook.ai (or Sudowrite, Scrivener, Novelcrafter), use GETebook.ai to generate the cover, then import the manuscript into Vellum for final formatting polish before uploading to Amazon KDP, Apple Books, and IngramSpark. For authors who want the cleanest-looking print and ebook files money can buy, Vellum is still the finish line. GETebook.ai's job is to get the draft and cover ready for that final polish pass, faster than any manual alternative.

    Frequently asked questions

    Is Vellum an AI writing tool?+

    No — Vellum is purely a formatting tool. It takes a finished manuscript (from Word, Scrivener, or Google Docs) and produces beautifully-formatted EPUB and print PDF files. There's no writing AI, no cover design (beyond basic ebook cover tools), and no drafting features. GETebook.ai solves the opposite end of the pipeline: AI drafting + cover, with good-enough export.

    Which produces better-formatted eBooks?+

    Vellum wins decisively on formatting quality. Its typography, chapter openers, drop caps, and ornamental breaks are genuinely the best available to indie authors. GETebook.ai's export is clean and publish-ready but doesn't match Vellum's polish for authors who want magazine-quality interior design.

    Can I use GETebook.ai for drafting and Vellum for formatting?+

    Yes, this is the standard pro stack. Generate the manuscript in GETebook.ai, export to docx, import into Vellum, apply styles, and export the final EPUB / print PDF for upload to Amazon KDP, Apple Books, and IngramSpark. Works cleanly for fiction and non-fiction.

    Does Vellum work on Windows?+

    No — Vellum is Mac-only and there's no official roadmap for Windows or Linux support. The common workaround is using a cloud Mac service like MacInCloud for $20–$30/month, but it's awkward. GETebook.ai runs in any browser including Windows and Linux.

    Is Vellum worth $249 if I'm a new indie author?+

    Depends on publication volume. If you're shipping 5+ books in the next 3 years, yes — Vellum pays for itself through time saved on formatting plus the professional output. If you're writing one eBook, Vellum is overkill and GETebook.ai's built-in export is sufficient.

    Can Vellum generate book covers?+

    Vellum has basic ebook cover generation using built-in typography templates — fine for a simple ebook cover but not the full cover design (especially for print with spine and back copy). Most Vellum users pair it with a dedicated cover designer (99designs, MiblArt) or use Canva. GETebook.ai's AI cover generator handles full covers.

    Does GETebook.ai replace Vellum for serious publishing?+

    Not entirely. For indie authors targeting professional-quality print and ebook output, Vellum's formatting polish is still the gold standard. GETebook.ai replaces drafting and cover generation; Vellum handles final formatting polish. The tools are complementary, not substitutes, for serious publishers.
