Caudexus

cau·dex, noun · Latin

The trunk of a tree; the block of wood split into tablets and bound: the earliest form of the book.

The writer’s home.

Caudexus is one place to write, plan, and organize every kind of writing: a novel and its world, a screenplay, a memoir, a thesis, and the research behind them all. It works offline, it keeps your words on your machine, and it stays as light or as deep as the work demands.


One place. A book and its research. A screenplay and its outline. A world and every story set inside it. Work that spans years deserves better than a folder of scattered documents, so Caudexus keeps the writing and everything that supports it together.

Yours. Your work lives on your device first and goes wherever you go. It is there on the train, in the archive, and on a plane. Export everything, any time, in formats other tools can read.

Quiet. A professional instrument that gets out of the way. Start with a blank page and nothing else, or open every tool the work calls for. The page stays the loudest thing in the room.


Inspiration flows wherever you go. So does Caudexus.

Caudexus is in a private beta with a small group of working authors. Public sign-up opens soon.
