You download the Claude app, go to start, and you're staring at three choices: Chat, Cowork, and Code. Which do you pick? It's the most common "where do I even begin" question I see — so here's the plain-English breakdown and exactly who each one is for.
The fast answer: Chat to think (brainstorm, write, ask). Cowork to do everyday work (it touches your real files and apps and remembers context). Code to build software (websites and apps). If you're a business owner just starting out, Cowork gives you the most leverage.
Chat — the conversation
This is the classic AI experience: you talk, it answers. Great for brainstorming, writing emails and content, getting quick answers, and thinking out loud. It doesn't touch your files or do tasks beyond the conversation — it's the "ask anything" mode.
Use it when: you want a quick answer, a draft, or to think something through.
Cowork — Chat with arms
Cowork is the one most people sleep on, and it's the most useful for running a business. Think of it as Chat that can actually do things:
- It connects to a folder on your computer and to external apps (like your CRM).
- It reads and writes real files and performs actual tasks.
- It carries memory from session to session — you drop files in your folder that tell it who you are and how you like to work, so every session starts from your "instruction manual" instead of from scratch.
- It gets smarter the more you use it, because the context builds up.
Use it when: you want AI doing real work with your real files — not just talking. For most business owners, this is home base.
Code — for building software
Code connects directly to a codebase and lets Claude work inside actual software projects — building apps and websites. It's aimed at developers, but you don't have to be a pro coder: beginners use it to build real websites by describing what they want in plain English.
Use it when: you specifically want to build something on the internet — a website or an app. If you never plan to build software, you can skip it.
Quick comparison
| Mode | What it does | Best for |
|---|---|---|
| Chat | Conversation, writing, quick answers | Everyone — thinking & drafting |
| Cowork | Reads/writes your files & apps, remembers context, does tasks | Business owners — everyday work |
| Code | Builds & edits real software projects | Building websites & apps |
"Should I run Code in the desktop app or in VS Code?"
Common follow-up. Both run the same Claude Code under the hood. The desktop app is simpler to start with. Running it inside VS Code (the free code editor) gives you a real workspace where you see your files and changes side by side — the more common setup once you're building actual projects. For learning to build websites, VS Code is the popular pick.
My recommendation: Start in Cowork, set up your folder, and work from there — it's where a non-developer gets the most done. When you're ready to actually build a website or app, that's when you move to Code (in VS Code).
