How to Use AI

Setting Up Claude

Claude is made by a company called Anthropic. People tend to reach for it when they want careful writing or a problem worked through slowly. This page walks you through setting it up.

If you haven't decided whether Claude is your tool, the Pick a Tool page compares it to ChatGPT and Gemini without crowning a winner. The three are close, and everything you learn here works the same in all of them. If you're here, you've either chosen Claude or you're trying it alongside another tool. Either is a fine reason to keep reading.

Take it slowly. The whole setup is about fifteen minutes if you stop to breathe. You can always close the page and come back tomorrow.

Before you start

Open a separate browser tab for this page so you can keep reading while you do the setup. If you don't know how: right-click the link you want to open in another tab, and choose "Open in new tab."


Getting to Claude

Open a new tab in your browser: Chrome, Safari, Edge, Firefox, whichever one you usually use.

Click in the long white bar at the top (the address bar, where website addresses show up). Type this exactly:

claude.ai

Press Enter on your keyboard.

What you should see: a clean page with the word "Claude" near the top, and a big button that says either Sign up, Get started, or Try Claude. There's usually a small drawing or pattern in the background; that's normal.

If you see something different (a broken page, a search engine, a different website), you probably typed the address wrong. Go back to the address bar and try again. It's claude.ai (not .com, not .org). Nothing fancy.


Making your account

Click the Sign up (or Get started) button.

Claude will offer you two ways to sign up:

Pick whichever feels easier. The Google way takes about ten seconds. The email way takes about two minutes because you'll need to switch to your email, open the verification message, and click the link inside it.

What you should see after signing in: a mostly-empty screen with a big text box in the middle that says something like "How can I help you today?" or "Message Claude..." That's the main Claude chat. You're in.


About the plans

You're now on the Free plan automatically. You didn't pay anything. Nothing is going to charge you.

Here's the honest version of what each plan does:

When to upgrade

Don't upgrade today. Play around on Free for a day or two, get comfortable with the chat. When you're ready to do the exercises on the Projects page, that's when you'll need Pro. You can upgrade any time in two clicks.

When you are ready to upgrade: click your name or the little profile circle in the bottom-left corner of the Claude page. A menu pops up. Click Plans or Upgrade. Pick Pro. Enter a credit card. That's it.

When to move from Free to Pro Stay on Free until you hit a limit or need Projects, then move to Pro. Max and Team can wait. Free Pro hit a limit, or need Projects Max, Team: skip
Start on Free. Move to Pro when a limit gets in your way or you reach the Projects page. Most people never need Max or Team.

Turning on the good features

Claude has a few features that make it much more capable. They're turned off by default on some accounts. Turn them on now so they're ready when you need them.

Find the settings. Look at the very bottom-left corner of the page. You'll see either your name, your initials, or a little profile circle. Click it. A small menu pops up above it.

From that menu, click Settings.

What you should see: a settings screen with a list of categories on the left: things like "Profile," "Appearance," "Feature preview," "Privacy," and so on.

Click Feature preview (sometimes called Beta features). This is a list of features Claude is trying out. Each one has an on/off switch next to it.

Turn these on by clicking the switch next to each one:

If you don't see one of these: don't panic. Anthropic renames and moves features every few months. Just turn on whatever is available. If they're all on by default when you look, even better.

When you're done, click out of Settings (there's usually an X in the corner, or just click outside the settings box).


A quick tour of the Claude screen

Before you leave, get familiar with what you're looking at. There are really only three parts to notice. Here's roughly what the page looks like, with the important spots labeled.

Annotated wireframe of the Claude.ai interface claude.ai + New chat RECENTS First conversation A test question Cover letter draft PROJECTS Lab report, BIO 210 + Create project P your account Claude Sonnet 4.6 ▾ How can I help you today? Message Claude... THE SIDEBAR past chats, your Projects live here SETTINGS click your profile circle here MODEL SELECTOR TYPE HERE where your messages go
Four things to notice on the Claude page. The sidebar (with Projects for later), the profile circle (settings), the model selector, and the big message box in the middle.

The big text box in the middle. This is where you type your questions. Below the box are small buttons for attaching files, taking a picture, or recording your voice. You don't need any of those today.

The left sidebar. Down this column you'll see:

The model dropdown. Near the top of the chat, there's a small dropdown that probably says Claude Sonnet or Claude Opus followed by a number. Those are different versions of Claude. Sonnet is faster. Opus is slower but thinks harder. You don't need to change this; whatever's selected by default is fine.

Which model, in plain terms

Once you're comfortable, this dropdown is worth understanding, because the same idea shows up in every AI tool. There are really two flavors:

The fast, everyday model (here, Sonnet). Great for roughly 90% of what you'll do: rewriting an email, drafting captions, brainstorming, cleaning up a paragraph. Quick and more than smart enough.

The slower "thinking" model (here, Opus, or a "thinking" toggle if you see one). It deliberately pauses to work through a problem step by step and check itself. Reach for it when the task is hard: untangling why your numbers don't add up, planning something with lots of moving parts, troubleshooting a stubborn problem.

Simple rule: fast model for most things, thinking model when the problem is hard. If you're ever unsure, the default is a fine place to start.


One small test

Before you close the page, type this into the chat and press Enter:

Hi Claude. I'm just learning how to use AI properly. Can you explain, in plain English for someone who isn't technical, what makes you different from ChatGPT? Keep it to two short paragraphs.

Read what comes back. Notice the tone: Claude tends to be a bit more careful and explain-y than ChatGPT. That's useful when the answer matters. Less useful when you just want a one-line response (we'll fix that on the Prompting page).

Don't do this yet

Don't start loading all your real material into this main chat. Everything you type here stays in this one conversation, and when you close it, Claude forgets it.

The whole point of the next couple of pages is to set up a Project, a permanent home for the information you keep coming back to, so it doesn't get forgotten. Hold off on the real work until you get there.

A word on what Claude remembers

Two different things are easy to mix up. Inside a single conversation, Claude holds everything you've said so far (its context window, explained on the Basics page), and forgets it all when you close the chat. Separately, Claude can carry some memory across chats, so it recalls a few things about you from one conversation to the next; look for a memory or personalization setting, and note that you can view and clear what it has kept. The exact wording moves around, so search Settings for "memory" if you don't see it.

For the work in this guide, the reliable way to make Claude remember what matters isn't memory at all. It's a Project, where your files and instructions live permanently and get loaded into every chat automatically. That's the next thing you'll build.

Quick check

You want to create a Project in Claude so it remembers the material you keep coming back to. Which plan do you need?

Answer: Projects are a Pro feature. The Free plan lets you try the chat, but to build a Project with Custom Instructions and uploaded files, you'll need Claude Pro.

You don't need to upgrade today. You can read the rest of the guide on Free and upgrade only when you're ready to build your first Project.

Where to check this

Claude's plans, features, and settings change over time. For current details, Anthropic's own help centre at support.anthropic.com is the reliable source. Search there for a feature name if a setting has moved since this was written.
