One-liner: Claude Cowork is an AI agent that lives on your desktop. It understands your files, apps, and workflows - plans before it acts, and executes multi-step tasks from start to finish - like having an employee who never gets tired and never forgets your instructions.
Most AI tools suggest answers. Claude Cowork does something different - it reads your actual files, connects to your real apps, and then plans and executes complex tasks from start to finish.
Think of it less like a chatbot and more like delegating to a smart assistant. You describe what you want. It figures out the how, shows you the plan, and does the work.
From the transcripts: "Most AI tools generate suggestions, and then leave the action to you. Claude Cowork creates a plan, shows it to you, and then executes it step by step while displaying progress."
