Getting started
How does version history work?
Cast checkpoints your whole project automatically — while you edit, and right before the risky moments: an export, Enhance voice, a re-transcribe, a bulk cleanup. Open the history from the clock icon in the top bar → "Version history…" and restore any checkpoint.
You never create a checkpoint by hand and you cannot forget to. While you are actively editing, Cast cuts one roughly every half hour of work; on top of that it always takes one just before anything that changes a lot at once — so "Before export" and "Before re-transcribe" are sitting there when you need them. Each entry in the list says what it was, not a version number.
Restoring is safe by construction: before a restore, Cast checkpoints the state you are leaving, and the restore itself becomes a new step in the history. Nothing is ever deleted from the timeline — if you restore and change your mind, restore forward again.
If you would rather compare than roll back, Duplicate turns any checkpoint into a new project and leaves the current one exactly as it is.
On the free plan you see the last 7 days of checkpoints. Older ones are kept, not thrown away — upgrading unlocks the full history of every project retroactively.
