The working mode of Claude in which Claude completes tasks with files, apps and the browser itself instead of only answering in the conversation.
Cowork is available on paid plans only. Claude reaches folders on your computer only through the desktop app. In the new Claude interface, rolled out since September 2026, chat and Cowork are one conversation and Claude picks the right tool itself. In the previous interface you choose between “Chat” and “Cowork” in the message box.
Example from Basics
In the course's fictional plant shop, Claude sorts the Customer Care folder with the ticket exports in Cowork.
Basics: “Claude bedienen”. In the Werkbank course room, with sign-in.
