What is Claude Cowork? All You Need to Know

Anthropic’s Claude Cowork (often shortened to Cowork) is a newly announced research-preview feature that brings agentic, file-aware capabilities from Claude Code into the regular Claude desktop experience. Rather than only answering questions or generating text, Cowork is designed to let users delegate multi-step, knowledge-work tasks—for example: organize a project folder, extract data from receipts and screenshots, draft a status report from a collection of documents, or wire up lightweight automations to third-party services—by giving Claude sandboxed access to a specified folder and optional connectors. The goal is to let non-developers benefit from the same “delegate and come back later” workflow that developers had been using with Claude Code, but without the technical setup.
