You open it up and there are several things called Claude, none of the names mean anything obvious, and you pick one at random and hope.
Here's the whole thing in 4 lines:
- Chat — ask it something, get an answer
- Cowork — give it a job and let it go do it on your computer
- Code — build or change software
- Design — make something that has to look good
That's genuinely it. Now the useful detail.
Chat
The normal one. The box you type in.
Use it for: questions, writing, thinking something through, pasting a document and asking about it, rewriting an email, checking your logic.
It's the right answer far more often than people think. Most of what you need is a conversation, and people skip past it looking for something more impressive.
Turn connectors on and Chat gets a lot stronger, because now it can go look in your email or your drive instead of waiting for you to paste things. That's here.
Cowork
This is the one people haven't tried and it's probably the one that changes your week.
The difference: Chat tells you how. Cowork goes and does it, on your actual files, on your actual computer, while you go do something else.
Use it for:
- Renaming or sorting hundreds of files
- Turning a pile of receipts or notes into a proper report
- Building a spreadsheet with real formulas from your data
- Anything that's 40 small boring steps
The mental shift: you're not asking a question, you're handing over a task. "Go through this folder of invoices, pull out the date, vendor and amount, and build me a spreadsheet sorted by date." Then you close the laptop lid... actually no, don't do that. It needs the app open. But you can go make coffee.
Two honest warnings. It burns through your usage allowance way faster than Chat, because it's doing many steps instead of one. And I wouldn't point it at a folder of genuinely sensitive personal or financial records the first time you try it. Start on something where a mistake costs you nothing.
Rest of it's yours
Drop your email and the whole thing opens up right here. No waiting on a confirmation, no download, nothing to install.
You'll also get the new ones as I make them. Leave whenever, no hard feelings.
Code
For building software. This is what I use for most of what I build.
Use it for: building a tool, fixing a website, writing a script that does something on a schedule, anything where the output is a working program.
You do not need to be a developer to use it. I want to be clear about that, because the name scares people off. You describe what you want in normal words and it writes and runs the code. You still need to be able to say what you want precisely and notice when the result is wrong, but that's a different skill from knowing a programming language.
That said: if you've never touched it, don't make this your first stop. Get comfortable in Chat first.
Design
For things that have to look right. Decks, one-pagers, flyers, mockups, a layout you'll actually hand to somebody.
Use it for: a pitch deck, a one-page proposal, a flyer, a rough version of a page before you build it.
The reason it exists separately: you can nudge things visually instead of describing every change in words. Much faster than asking Chat to "make the heading bigger" 15 times.
The 5 second decision
| What you're doing | Open | |---|---| | I have a question | Chat | | Rewrite this / summarize this | Chat | | Do this boring job on my files | Cowork | | Build or fix a tool or site | Code | | This has to look good | Design | | I don't know | Chat |
That last row is real. Chat is the right default. Start there, and if it says "here's how you would do that," that's your signal you wanted Cowork.
The mistake almost everybody makes
Using Chat for a job that needs Cowork, and then doing 40 steps by hand because Chat politely explained all 40 to you.
If you catch yourself following instructions it just gave you, one at a time, on your own computer... stop. That's the exact job Cowork exists for. You just had it write you a manual instead of doing the work.
What I'd do this week
Pick one boring repetitive thing on your computer. A messy folder. A pile of PDFs. Notes that need to become a document.
Open Cowork and describe the job in plain words like you're telling somebody what you need. Then watch it actually do it.
That's the moment this stops feeling like a chatbot and starts feeling like help.
