Atticus

Atticus is a modern book writing and formatting platform built by authors for authors, designed as the cross-platform alternative to Vellum. While Vellum is macOS-only, Atticus works on Windows, Mac, Linux, and Chromebook as a Progressive Web App (PWA), making professional book formatting accessible to every self-published author regardless of their operating system. The platform combines a distraction-free writing editor with powerful formatting templates, allowing authors to write, format, and export their books from a single application.

What makes Atticus stand out is its combination of writing and formatting in one tool at a significantly lower price point than competitors. At $147 for a one-time lifetime purchase, it undercuts Vellum's $249 price while offering cross-platform compatibility and features like a custom theme builder with over 1,200 unique design combinations, 1,500+ supported fonts, and cloud storage with automatic backups. The platform is actively developed with regular feature additions based on author community feedback, including upcoming version control for manuscripts.
