In this lesson, you'll learn to define Claude Cowork, understand Cowork as Claude working in your environment, and distinguish between Chat, Cowork, and Code.
Cowork is a mode of Claude inside the desktop app where Claude works on tasks alongside you. You point it at a folder on your computer, connect the apps where your work lives (Gmail, Slack, Google Drive, your calendar), and describe what you want done. Claude makes a plan, works through the steps, uses the tools and files it needs, and saves a real deliverable back to your folder. You can also run Cowork in the cloud (in beta, on eligible plans) to start and check on tasks from the web and the Claude mobile app.
The mental model that matters most: Cowork is about delegating, not just chatting. Chat is still incredibly powerful — it's where you'll go to think through problems, draft and refine, brainstorm, ask questions, and have Claude as a sounding board. Cowork doesn't replace any of that. What it adds is something new: the ability to hand Claude an entire piece of work — context-gathering, analysis, file production, tool use — and have it come back completed.
This is the single biggest shift for new Cowork users to make. Most people's first instinct — coming from Chat — is to type a question, see what comes back, type a follow-up, and iterate. That works in Cowork too, but you'll get the most out of it when you reach for it for the work you'd normally do yourself, not the work you'd normally ask about.
Mechanically, Chat is turn-by-turn. It can pull from your tools, but you stitch the steps together yourself. It is purpose-built for bounded exchanges and quick thinking. Cowork, on the other hand, sustains a whole piece of work: it pulls from many tools at once, runs through multi-step plans, and returns the finished output.
Cowork works in your environment. Not adjacent to it.
The three modes are built for different shapes of work.

Chat is for thinking with Claude. Cowork is for delegating to Claude. Code is for building software with Claude. Most knowledge workers will live in Chat and Cowork — and use them for very different things.
Think about a task you did recently where the value was in the doing, not just the thinking. Maybe it spanned multiple tools. Maybe it ended in a deliverable you assembled by hand. Maybe it's something you do every week that you'd love to leverage AI to handle for you.
Hold on to that task — you can come back to it in Lesson 3 when you start identifying your own Cowork use cases, and again in Lesson 4 when you delegate your first real task.
In the next lesson, you'll get Cowork set up: install the desktop app, point Claude at a working folder, add your first connectors, and learn the permissions model that keeps you in control of what Cowork can do.
