A designer in Adobe InDesign selects text or graphics frames and exports them as "assignments" ( .icma files) or individual InCopy stories ( .icml files).

The editor opens these assignments in InCopy. They can see the full page layout for context but can only edit the specific text frames assigned to them.

Adobe InCopy 2021 is a professional word processor designed to integrate perfectly with Adobe InDesign, allowing writers and designers to work on the same document simultaneously without overwriting each other's work. This collaboration is handled through a "LiveEdit" workflow where content is checked in and out to prevent conflicts.

The primary way to use InCopy is through a managed workflow system.
