Sunder

Edits Claude has proposed. Nothing changes in the book until you tap Accept. “Go to passage” opens the chapter with the passage highlighted.

Changes a name everywhere in every chapter and the bible. Whole words only. Every changed file is backed up first.

Saves to the same .docx Google Docs uses. Don't have this chapter open in Google Docs at the same time.

Whole-book snapshots

A snapshot copies every file in the book folder into Sunder Backups in Google Drive. One is also taken automatically every 6 hours when something changed. Loading a snapshot puts every file back the way it was — and saves the current versions first, so nothing is lost.

Single-file backups

Every rename, renumber and restore saves a copy here first. Restoring never deletes anything: the current version is backed up before it's replaced.
