# What is Collab Sync?

Collab Sync keeps a folder you choose mirrored on two Macs that both run Storage Studio and are paired through Bridge — for example your project folder at home and at the office, or a folder shared with a collaborator. Each Mac keeps a real local copy, and changes are sent across within seconds of saving.

Nothing goes through the cloud: it uses the same direct, end-to-end encrypted Bridge link. You pick a direction — this Mac to the other, the other to this one, or both ways — and the other Mac's owner accepts before anything is created there.
