I didn't really get Claude because I was content with ChatGPT.
I'd heard of it. I knew it was an AI tool. But every time I opened it, I felt like I was missing something. Like everyone else knew how to use it and I was just asking it random questions and hoping for the best.
So here's what I wish someone had told me early on.
First. What even is Claude?
Claude is an AI assistant made by a company called Anthropic. Think of it like a very capable thinking partner that you can talk to in plain English. You don't need to know how to code. You don't need a tech background. You just type what you're working on and it helps you work through it.
It can write, research, summarize, explain, brainstorm, and answer questions. The more specific you are with it, the better the output.
That's the basics. But here's where it gets more interesting.
There are actually three different ways to use it.
When I first started I thought Claude was just a chat window. It is. But it's also a lot more than that. Once you download the desktop app, you get access to three different modes. Each one is built for a different kind of work.
Chat
This is your starting point. Same thing as the browser version at claude.ai but with a few extras that come from running it on your computer.
You can double-tap the Option key on Mac and it pulls Claude up as a small overlay on top of whatever you're already working on. You never have to stop what you're doing to ask a question. You can also share your screen with it, take a screenshot and paste it in, or just talk to it out loud instead of typing.
Use Chat when you're going back and forth on something. Quick questions. Brainstorming. Drafting something fast. It's conversational and immediate.
I use it when I'm staring at something and need a second opinion in under two minutes.
Cowork
This is where things start to get serious.
Cowork is built for tasks that take real effort. Research across multiple sources. Pulling together documents. Summarizing large files. It can work through a whole project and hand you something finished at the end.
The big difference from Chat is that Cowork can run multiple things at once, work through your files directly, and even handle recurring tasks on a schedule. Set it up once and it runs automatically every morning or every week.
I think of it like this. Chat is having a quick conversation. Cowork is handing off a real project.
This is also where building a proper workspace pays off. I set up a personal AI brain inside Claude — a folder structure, standing rules, and a personal OS file that loads automatically every session. Claude knows my context, my workflow, and how I want things formatted before it touches anything. No re-explaining from scratch every time. If you want to set that up yourself I wrote a full walkthrough on how to do it in an afternoon here.
Code
If you're a developer or want to get into building things, this is where you go.
Code gives Claude direct access to your codebase. It can read your project, write and modify code, run commands, and show you exactly what changed before anything gets saved. You can choose how much control it has — from approving every single change to letting it work more independently while you review at the end.
If you're not a developer, you probably don't need to worry about this one yet. But it's worth knowing it exists.
So which one should you start with?
Chat. Full stop.
Open it. Ask it something you're actually working on right now. A decision you're trying to make. A document you need to write. A thing you're trying to understand. Don't overthink the prompt. Just start talking to it like you'd talk to a smart friend who has a lot of time.
Once you're comfortable with Chat, move to Cowork and start building out a real workspace. Give it an actual project. See what it produces. The AI brain post above is the fastest way to get that set up properly.
The biggest mistake I made early on was trying to understand all of it before I started. You don't need to. Just start. The rest clicks into place once you're actually in it.
