ProBookOS^™

Drop in your manuscript and ProBookOS reads it: who your readers are, what makes the book unlike its shelfmates, and three ways to position it. Pick your angle and we write your back cover copy to match — yours to keep, no card needed. One sample per author.

Your manuscript is 100% protected. It stays private to your own workspace, no one reads it, it is never shared or published, and it is never used to train AI — and you can delete it whenever you like. How we protect it
