The Author Notebook Windows desktop app is local-first: your project is stored on your device and works without an internet connection.
On Windows, Author Notebook stores your chapters, characters, and worldbuilding on your device, so writing does not depend on your connection.
The browser-based web app can be used for writing, but signing in and any optional cloud sync require a network connection. For fully offline use, the desktop app is the better fit.
If you want to work across devices, Cloud Projects can sync selected workspaces when you are online. It is a separate, opt-in feature, not a requirement.
Yes, on the Windows desktop app — it is local-first and does not require an internet connection to write and save your project.

Export a portable .anb project file, which you can store manually or move to another device.
