You’ve typed a question into a chat box and gotten an answer back. Everyone has. This is that, and then a step further.
Claude Code is an agent: an AI that runs in an app on your desktop, sees the folder you point it at, and can read and change the files inside it.
That’s the whole idea. The rest of this page exists so you don’t think it’s something it isn’t.
Claude vs. Claude Code
Two things, one root word, worth getting straight before you install anything.
- Claude is the model — the AI brain Anthropic trains. It lives at claude.ai, inside apps, inside other products. It answers when you write to it.
- Claude Code is what happens when you give Claude hands. The same model, plus tools — open a file, change a line, run something, look something up — wrapped into an app that sits on your computer.
Same brain. Very different reach.
Not just a smarter chatbot
This is the part that trips people up, especially if you’ve spent time with a chatbot in a browser tab.
A chatbot can describe what’s probably in your folder. It can guess well. It can also be confidently wrong, because it has no way to actually look.
Claude Code can open your folder, read what’s really there, and tell you. Then open one of those files. Then change a line in it. Then check that the change worked.
A chatbot talks about your work. An agent does some of it.
The difference sounds small written down. In practice it’s the difference between getting advice and getting help.
What that gets you
Once it’s installed — the next page, about five minutes — you can do things like:
- Point it at a folder and ask “what is all this?” It reads the files and tells you.
- Hand it a messy spreadsheet and ask it to clean it up. It opens the file and does the work.
- Give it a folder of meeting notes and ask for a summary of what was decided.
You don’t copy-paste your work into a chat window and copy the answer back out. Your files stay where they live, and Claude works on them where they are.
What it isn’t
It isn’t a replacement for knowing what you want. It isn’t reliable enough to trust without looking — that comes up later on this path, and it’s the single most important habit here. And it isn’t a terminal: you will not type a single command to follow this path.
