Checkpoints

Checkpoints let you save named snapshots of annotation progress within a session. This is useful for multi-day annotation, version control of annotation state, or marking a session as ready for review.

Creating a checkpoint

Session → Save Checkpoint (or Ctrl+Shift+S)

• Enter a name (e.g. first-pass, after-review, final)
• Optional notes
• The checkpoint is saved inside the session folder

Restoring a checkpoint

Session → Manage Checkpoints shows the list of saved checkpoints.

• Click any checkpoint to preview its annotation state
• Click Restore to revert the session to that snapshot

When to use checkpoints

Scenario	Checkpoint name suggestion
End of a session annotation pass	pass-1
Before making a large correction	pre-correction
Annotation complete, ready for IRR	ready-for-irr
After IRR resolution	final

Tip

Creating a checkpoint before loading a review layer is good practice — it preserves your independent annotation state.
