Atticus

Atticus combines a word processor and book formatter into a single web app that runs on any device—Windows, Mac, Linux, or Chromebook. Created by Dave Chesson of Kindlepreneur, it's positioned as the cross-platform answer to Vellum at a lower price point.

What You Get

• 17+ formatting themes: Pre-designed chapter themes with 1,200+ unique combinations of fonts, headers, and decorative elements
• Custom theme builder: Adjust fonts, trim sizes, drop caps, callout boxes, and chapter headings per project
• Writing mode: A dedicated word processor for drafting, with drag-and-drop chapter organization, writing goal tracking, and offline support via cloud sync
• Export formats: Produces KDP-compatible ePub and print-ready PDF files tested against Amazon KDP, IngramSpark, and Apple Books
• Version control: Save and revisit previous manuscript versions within the platform
• Special formatting: Supports text message scenes (iOS and Android styles), callout boxes, footnotes, and full-bleed images

Who It's For

• Windows and Linux authors: Vellum is Mac-only; Atticus gives non-Mac users access to comparable professional formatting
• All-in-one seekers: Authors who prefer to write and format in the same tool, avoiding the Scrivener → Word → Vellum pipeline
• Fiction and non-fiction authors: Theme variety covers genre fiction, literary fiction, and non-fiction layout needs

Pricing: $147 one-time purchase includes all future updates. 30-day money-back guarantee. No subscription fees ever.

Strengths

• Cross-platform: Unlike Vellum, works on Windows, Linux, and Chromebook without virtualization or a Mac
• One-time pricing: $147 vs. Vellum's $249 (ebooks only) or $249.99 (ebooks + print), with updates included at no extra cost
• Offline capable: Works without an internet connection after initial setup; changes sync to the cloud when reconnected

Limitations

• No spell check or grammar check: The writing editor lacks built-in spell checking—a separate tool like ProWritingAid or Grammarly is still needed for proofreading
• No global find/replace: Searching and replacing text across the full book is not supported within the app, a significant gap for manuscript editing
• Writing features less mature than Scrivener: No outlining, research management, or cork board; more suited to linear drafting than complex project management

Alternatives

Vellum ($249, Mac-only) produces marginally more polished output and is favored by authors already on Mac. For writing only, Scrivener ($59.99) remains the power-user choice, though it requires a separate formatting tool.
