Yes Partial No

Scope

This is the most important distinction: Vellum is a formatting and export tool. Bookshaper is a writing, organization, analysis, and formatting tool. If you already have a writing workflow you love and just need beautiful output, Vellum is purpose-built for that. If you want one tool for the entire journey from first draft to publish-ready files, Bookshaper covers the full pipeline.

Formatting quality

Vellum's formatting is exceptional — its templates are among the most polished in the industry, with a curated selection of decorative elements. Bookshaper ships 60 built-in templates organized into 9 genre / era categories (Modern Literary Fiction, Commercial Thriller, Contemporary Romance, Epic Fantasy, Cozy Mystery, YA / Crossover, Victorian Classic Reprint, Mid-Century Pulp / Noir, Memoir & Narrative Nonfiction) plus submission and accessibility formats — so you start from a look that matches the kind of book you're writing. Underneath, a style editor gives you direct control over 41 typographic targets including running headers, chapter openers, body text, margins, and page layout, plus thousands of built-in ornaments for scene breaks and chapter headings. The result is comparable quality, more starting points, and more flexibility — running on Windows and Linux as well as macOS.

Writing environment

Vellum has a basic text editor for making small edits, but it's not designed for drafting or revising a manuscript. Bookshaper provides a full scene-based writing editor with autosave, manuscript preview, card view, outline view, character profiles, location tracking, and a research notebook.

AI analysis

Vellum has no AI capabilities. Bookshaper produces a prioritized coaching report with actionable guidance on structure, pacing, character arcs, themes, emotional cadence, and continuity. An AI Chat panel lets you ask follow-up questions, brainstorm ideas, or get craft advice specific to your manuscript. This gives authors the kind of editorial feedback and ongoing conversation that would otherwise require a professional developmental editor.

Pricing and platform

Vellum is Mac-only with a one-time price of $199.99 for ebooks or $249.99 for ebooks plus print. Bookshaper starts at $5.99/month and runs on macOS, Windows, and Linux. Vellum has no Windows or Linux support at all.

The bottom line

Vellum is a best-in-class formatting tool and a great choice if your workflow already includes a separate writing app. Bookshaper is the better fit if you want to write, organize, analyze, and format your manuscript in a single application — especially if you're on Windows or Linux.
