Meet Anthropic & Claude

Start typing "Claude" into a search bar and the suggestions stack up fast. Claude. Claude Code. Claude Cowork. Claude Design. Claude for Chrome. Claude for Slack. A couple of odd words like "Opus" and "Sonnet" drift past. And the very normal reaction is a small inward sigh: great, a whole stack of new things I'm apparently supposed to learn.

Here's the good news, though — there isn't a stack. There's one.

So who makes this?

A quick "who" before the "what," because it tells you something worth knowing about the tool you're about to lean on.

Claude is made by a company called Anthropic. The short version: it's an AI company that introduces itself, first thing, as a safety company. The pitch is powerful AI, built carefully.

That's more than a slogan. Anthropic is set up as a public benefit corporation — legalese for "our mission officially includes being good for people, not just turning a profit." There's even an independent trust whose job is to appoint board members and keep that mission ahead of investors. The phrase the company likes is a "race to the top" on safety: AI companies competing to be the safest, not only the most impressive.

You don't have to remember any of that. Just one thing worth keeping: the company behind Claude built its whole identity around being careful. When you're handing a tool your writing, your plans, your half-formed Tuesday-night ideas, that's a steadying place to begin.

What "Claude" actually is

Now the name itself. Claude is the AI — the actual intelligence you talk to, the thing that reads what you wrote and answers back.

If you took the first course, you already own the perfect picture for this. Remember the doorway? The chatbot is the doorway; the LLM is who's actually home. Claude is who's home. The chat app — what most people mean when they say "Claude" — is just the front door. The busiest door, the one nearly everyone walks through first. Still just a door, though.

And that's the key to the whole confusing list. Claude Code, Claude Cowork, Claude for Slack — those aren't other AIs. They're other doors into the same house.

One Claude, many doorways

So picture one Claude standing in the middle of a house, with a handful of doors leading in, each shaped for a different kind of work. You don't need the full floor plan today — the rest of this course opens each door in turn. But here's the lay of the land:

• The everyday door is the Claude app, on your phone or laptop or the web. It's the chat you might already know, and it's where most people spend all of their time.
• The "go do it for me" doors, like Cowork and Design, are for when you want Claude to take on a chunk of work and come back with it done, instead of just talking it through.
• The "come to my stuff" doors let Claude show up where you already are — inside your web browser, your Slack, your Microsoft Office.
• The builder doors, like Claude Code, are for people who write software.
• Underneath everything sit the engines: the models, with names like Haiku, Sonnet, and Opus. Think of them as different sizes of the same brain. We'll get to them.

Read that and you might feel the sigh creeping back. Five kinds of doors, really? So try sorting them by who they're for instead of what they do. Most of them, it turns out, aren't yours at all.

Which doors are yours

The first course laid out three ways of relating to AI. You can be the driver, who just wants to use AI well to get real things done. The mechanic, curious about what's happening under the hood. Or the engine designer, who builds AI tools from scratch.

That same lens sorts every door in this house. Most of them are driver doors — the app, the "do it for me" tools, the helpers that meet you in your browser and inbox. That's where you'll live, and honestly, that's nearly this whole course. A couple are builder doors, like Claude Code; if you don't write software, you have full permission to wave as you walk past and never once turn the handle. And the engines are an understand-it thing — you'll learn the names so they quit sounding like a secret code, and that's the end of it.

Where we head next

So there's the reframe. Not a dozen tools — one Claude, behind a handful of doors, most of them yours and a few you can happily ignore. The scary list turns into a menu.

Let's open the door you'll reach for most, the everyday Claude app, and see what it's actually like to step through.
