Overview

This guide explains how to set up Claude Cowork so it can reliably complete real work while you step away. The core idea is simple:

• Stop trying to write “clever prompts.”
• Start building better context (files + instructions + integrations) so Cowork can operate inside your real environment.

Cowork vs. Chat (what it actually is)

Claude on the web

• Works like a chatbot: you type → it replies.
• Mostly works through copy/paste and uploads.

Claude Cowork (desktop app)

• Runs on your computer.
• Can read and write to a local folder.
• Can create documents and spreadsheets directly.
• Uses clarifying questions instead of guessing.
• Can use plugins and connectors to specialize and pull live context.
