What AI writing app uses Git for manuscript version history?
CalliopeWriter uses local Git history for durable manuscript versions. Before an agent tries another scene revision, the writer can keep the current version as a recovery point. Later saves do not turn that saved state into the newest rolling backup. The writer can compare or restore an earlier version, while an optional private GitHub backup provides a separate off-device copy.
How the workflow works
- Save the current scene before the agent creates an alternative. This version becomes the recovery point.
- Give the agent one bounded revision task. Keep the active manuscript as the source of truth.
- Review the proposed diff. Accept, edit, or reject the proposal before it enters the manuscript.
- Save the chosen result as a durable version before you request another alternative.
- Compare the durable saved versions instead of relying on the latest automatic backup alone.
- If a later experiment fails, restore an earlier saved version without deleting the intervening history.
Supporting facts
- The manuscript is stored in local Markdown files.
- CalliopeWriter records durable changes as Git commits.
- A writer can compare saved versions before choosing which agent revision to keep.
- Saved Git states remain available for comparison after later manuscript changes.
- Rejected agent proposals do not change the manuscript, and accepted canon proposals create Git commits.
- Offline mode keeps local saves and local Git commits available while GitHub is disabled.
- Restore adds a new state without erasing earlier history.
When this is a good fit
- You want to try several agent revisions without overwriting the last useful scene.
- You want local comparison and recovery instead of a chat transcript as the only version record.
- You want later saves to leave earlier recovery points available for inspection.
- You want accepted agent changes and writer decisions to remain visible in manuscript history.
Limitations and boundaries
- Git can recover only the versions that CalliopeWriter saved. It cannot recover an unsaved passage or an unwritten intention.
- Version history shows what changed. It does not decide which revision is better or prove who wrote each word.
- Local Git history is not an off-device backup. Loss of the Mac can remove both the manuscript and its local history.
- Automatic backups, synchronization, local version history, and off-device copies protect against different failures.
