What you need for this one

Why this exists

There are several different ways to use Claude, they have overlapping names, and people bounce between them for weeks without ever knowing which one they should be in. It's a small confusion that quietly costs a lot of time.

Ten minutes now and you'll never wonder again. You'll also avoid paying for something you don't need, which is the other thing people get wrong here.

The idea

Same brain, different rooms. You choose the room by asking one question: does this need to touch my files?

That's the whole decision tree. Everything else is detail.

Room What it's for Touches your machine?
Claude app (web, desktop, phone) Thinking, drafting, questions, working something out No
Claude Code Doing — reading, changing, building, fixing real files Yes
Cowork Longer-running work you check in on rather than watch Yes, its own space
API Wiring Claude into software you're building Only what you wire up

For the next eight weeks you live in two of those. The app when you're thinking. Claude Code when you're doing. If you're unsure, ask whether the result is words or a changed file — words, use the app; changed file, use Claude Code.

One thing that catches everyone: Claude Code isn't one place. It's the same thing available in a few forms — inside the desktop app, in a terminal window, inside a code editor. Same tool, same behaviour, different windows onto it. You'll use the desktop app, because it's the one with a proper interface and you don't need a terminal for it. When you see people online in a black terminal window doing this, they're not using something better. Same thing, older window.

On plans. Prices and tiers change, so this is the way to decide rather than a number:

Upgrade on evidence, not on the assumption you'll grow into it. The evidence takes two weeks to arrive and it's free to wait.

Do

  1. Open the Claude app and ask it something that only needs thinking — a question, a draft, working through a decision. Note that it never asks about your files, because it can't.
  2. Look at what plans exist and what each includes.
  3. Pick the cheapest paid tier that includes Claude Code. Set it up.
  4. Write plan.md with three things: which plan, what it costs, and what would have to happen for you to move up.
  5. Put a note in your calendar two weeks out: check whether I'm hitting limits.
  6. Write yourself one line: when do I use the app, and when do I use Claude Code?

Step 4's third question is the one that matters. Writing down your upgrade trigger now stops you upgrading in three days out of vague guilt about it being slow.

Done when

Never do

Don't buy API access. Different product, different billing, not what you're doing. If a tutorial tells you that you need an API key for something in this course, you've wandered into a different course.

Don't run on the free tier. You will hit a limit in the middle of a lesson, and you'll blame the tool for something the plan did.
