Download & Install
ChapterMuse is a native desktop app for Windows and Mac — small, fast, and fully offline-capable.
ChapterMuse runs as a proper desktop application, not a browser tab. That means it launches from your Start menu or Dock, keeps its own window, and stores your manuscripts locally on your machine — so it's quick to open and never loses your place.
✦Quick start

- 2Run the installer and follow the prompts — it takes under a minute.
- 3Launch ChapterMuse from your Start menu (Windows) or Applications (Mac).
- 4Sign in with your ChapterMuse account to get started.
System Notes
- Windows and macOS desktop builds are available — pick the one that matches your machine
- The Mac build supports macOS 13 Ventura and newer, with native window controls and Apple Silicon, Intel, and universal packaging
- Your manuscripts live on your own computer — nothing is uploaded, and the app is quick to open
- Works fully without an internet connection — on a plane, in a cabin, anywhere
- New versions ship as fresh installers — download and run the latest one from chaptermuse.com whenever you want to update; your work and your licence stay exactly where they are
