I was not understanding when to use which so I asked Chat to help me understand better. Sharing what it explained. I hope it helps someone else wrapping your head around Claude. I have only been using ChatGPT.
The Big Mindset Shift First
Chat, CoWork, and Code are NOT different models or different versions of Claude.
They're the same Claude brain running in different environments — like the same person sitting at a different desk depending on the task.
Environment Think of it as...What makes it different
ChatClaude at a whiteboard Conversation — nothing is saved as a file
CoWorkClaude at a desk with a printer. Builds & delivers actual downloadable files
CodeClaude at a terminal. Runs real scripts, processes data, builds tools
The Yes/No Decision Map
Start here every time:

Do I need a FILE I can save, download, or send to a VA?
↓ ↓
YES NO
↓ ↓
CoWork → Chat
↓
Does it involve running a script, processing data, or building something technical?
↓ ↓
YES NO
↓ ↓
Code → Stay in CoWork
