About

Caption Forge

Features
Read full description

Revise a saved caption with a named change record, compare the saved and draft text, and restore a previous version into the editor. HOW IT WORKS 1. Open Revision Desk and choose a saved caption. 2. Edit the draft, describe why it changed and save a revision. The first revision also preserves the original text. 3. Load a previous version into the editor and save it as a new revision when ready. Existing caption writing and saved-caption workflows remain available. Revision saves protect against overwriting a caption that changed while being edited. WHAT TO KNOW Loading a version changes only the draft until you save. Calendar entries and previously shared copies are not rewritten. Character and word counts do not predict reach or engagement. History has an explicit limit and individual versions can be deleted. iPhone and iPad.
