1.2 · What is Cowork?
If you've used ChatGPT (or Claude in the browser, or Gemini, or any other chat AI), you already know the basics: type a question, get an answer. That mental model is the right starting point. Cowork builds on it.
But there are some key differences that change everything about how you work. Let's walk through them.
With ChatGPT, your workflow looks like this:
For a quick question, that's fine. For real work, the copying and pasting, back and forth, trying to give the AI enough context... it gets exhausting fast.
Cowork eliminates that entirely. It can already see your files. You don't copy anything in. Results appear as actual files on your computer. You don't copy anything out.
This is the biggest mental shift. When you use ChatGPT, you're having a conversation. You ask, it answers. You're the one who acts on the information.
With Cowork, you give it a task. "Summarise these meeting notes." "Turn this CSV into a chart." "Draft a follow-up email based on this conversation." And it does the task. The output isn't a chat bubble you need to copy from. It's a file on your computer, ready to use.
| ChatGPT | Cowork | |
|---|---|---|
| Where it runs | Browser tab | Desktop app |
| How you share files | Copy-paste or upload | Drag in, or point at a folder |
| Where results go | Chat bubble | Real files on your computer |
| Best for | Questions and brainstorming | Tasks and production work |
| Knows about your files | Only what you paste in | Everything you point it at |
This isn't about Cowork being "better" than ChatGPT. They're different tools for different jobs.
Need a quick answer to a question? ChatGPT (or Claude in the browser) is great. Need to brainstorm ideas? Chat is perfect for that.
But when the work involves your actual files, when you need something created or transformed or organised, that's where Cowork takes over. It's the difference between asking for directions and having someone drive you there.
Think of the last time you used ChatGPT for something that involved a lot of copy-pasting. Maybe you were reformatting a document, or extracting information from a spreadsheet, or trying to get a consistent output across multiple inputs.
Write that task down. We're going to do it in Cowork later, and you'll feel the difference immediately.
