Calamus is the writing studio for novelists who see the whole book at once. Most writers draft in one app (Scrivener, Ulysses) and reformat in another (Vellum, Atticus). Calamus does both on the same file: a full drafting studio — binder, corkboard, outliner, world-building — plus a compiler that outputs a retailer-ready EPUB or PDF with 1,900+ fonts. Native on Mac & iPad, fully offline, one-time purchase. Write, compile, publish.
