Why Koberger
Built for authors who publish more than once.
Koberger is built for a growing catalogue, not just a single book, with tools the desktop apps leave out.
A reusable Section Library
Write your author bio, also-by, and copyright once. Reuse them across every book, and update them everywhere at once.
Series and box-set tools
Keep a whole series formatted identically, check consistency across books, and apply one change to every title.
Rich content blocks
Rich content blocks, from text-message conversations to tables, verse, and callouts.
Watermarked advance copies
Export watermarked advance reader copies to share with reviewers, built in.

How is Koberger different from Vellum and Atticus?
Koberger runs in the browser on any device, bills monthly or yearly rather than as one large upfront fee, and is built for authors who publish more than once, with a reusable section library and series tools.
Do you use AI or train on my manuscript?
No. Koberger is a formatting tool, not an AI writer, and we never train on your manuscripts. Your writing stays entirely yours.

Bring the manuscript. Koberger handles the format.
