For anyone who's been quietly curious

Learn Claude.

Not a course. Not a manual. The version of this I wish someone had handed me when I started, the one that treats you like a smart adult who just hasn't sat down with it yet.

Your outcome contract0/3 done
  • A real first conversation with Claude
  • One prompt you'll actually reuse
  • One working Artifact you built
By the end of this page, not at the end. At the end.
Field note · before you click anything

There is one Claude.
Everything else is pretending.

There are dozens of sites, extensions, apps, and ads built to look like Claude, to sell you subscriptions, skim your credentials, or quietly install malware. None of them are Claude.

The only URL for Claude is
claude.ai
Built by Anthropic. Anything on a different domain, claude-ai.com, claudeai.app, getclaude.co, claude-pro.io, is not Claude. Close the tab.
01
The domain is claude.ai. Not claude.com, not claudeai.com, not claude-ai.io. If the URL bar doesn’t show claude.ai, you’re not on Claude.
02
The mobile app is published by “Anthropic, PBC” on the App Store and Play Store. Any other publisher name is a clone. Check before you install.
03
Never type a password into a Claude lookalike. Real Claude sign-in only happens on claude.ai (or an anthropic.com OAuth page).
04
Ignore paid ads at the top of a Google search. Type claude.ai into the address bar directly, or bookmark it from here. Scam sites buy the top ad slot.
When in doubt: come back to this page. The link above is the right one, forever.
A quick calibration

Why are you here?

Pick the one that's closest. I'll tailor a few notes throughout so this feels written for you.

Lesson 01 · 2 min

What Claude actually is

Claude is an AI assistant built by a company called Anthropic. Same category as ChatGPT. Different DNA, different instincts.

Think of it this way. If ChatGPT is the eager generalist who loves to show its work, Claude is the thoughtful collaborator who reads the whole email before answering, asks if it's missing context, and writes back the way you would if you had two more hours in the day.

It reads documents, drafts emails, writes code, plans trips, helps you think through hard conversations, translates, analyzes spreadsheets, builds small apps while you watch, and remembers what you're working on across weeks if you let it.

Lesson 02 · 2 min

The three things it's exceptional at

I.

Writing in your voice.

Paste three emails you've written and tell it "write everything in this voice from now on." It'll get disarmingly close. This single trick saves me hours a week.

II.

Holding a lot of context.

Drop in a 200-page contract, a year of meeting notes, or a photo of a whiteboard. Claude holds it, reasons over it, and cites the exact line you ask about. This is where it pulls ahead.

III.

Making small, usable things.

"Build me a tip splitter." "Build me a habit tracker for my kid." Claude will render a working tool in the side panel, called an Artifact, that you can actually use. The first time is a kind of small religious experience.

Lesson 03 · 1 min

Your first conversation

The trick isn't learning prompts, it's learning to talk to it like a human who's on your side. Here's what that actually looks like.

claude.ai · your first conversation

Real conversations aren't much more complicated than this. You are not in trouble. You are not being graded.

Lesson 04 · 2 min

Five prompts worth stealing

Copy any of these. Paste them into Claude. Fill in the brackets. They are the ones I actually use.

01The Sunday reset

I want you to act as a calm, thoughtful planning partner. Ask me 6 questions, one at a time, about what's actually on my plate this week (work, family, house, money, body, mind, anything I'm avoiding). After I answer all 6, write me back a single page titled 'The real list', sorted by what will make the biggest difference if I do it this week. No fluff, no hype words.

Best for: Sunday evenings. 10 minutes. Feels like journaling with a coach.
02The email I've been putting off

Help me write an email I've been putting off. Here's the situation: [describe in 2-3 sentences who it's to, what you want, and why it's awkward]. First, ask me one clarifying question. Then draft three versions, short & direct, warm & human, and firm but kind, and tell me which you'd send and why.

Best for: bosses, estranged friends, landlords, a kid's teacher.
03The dumb question

I want to understand [topic, e.g., how HSA contributions actually work, or what a mortgage APR really is] like I'm a smart adult who just never had it explained. No bullet points. Write it as a short, clear paragraph I could read out loud. Then give me one example using round numbers. Then tell me what people most often get wrong about it.

Best for: things you've been too embarrassed to google for the 4th time.
04Meeting → decision

I'll paste the notes from a conversation. Your job: extract (1) what was actually decided, (2) what's still open, (3) who owes whom an answer, and (4) the one thing that, if I don't do it by Friday, will derail this. Keep it under 150 words.

Best for: the 48-hour gap between meeting and forgetting the meeting.
05Build me a tool right now

Build me a small web tool I can use in my browser. It should [describe: e.g., let me track how much water I drink with big tap buttons and a reset each morning]. Make it beautiful, use warm colors, no login, and save my data locally. Show it to me as an Artifact.

This one is magic the first time. Seriously, try it.
Lesson 05 · 1 min

What it's NOT, the fears

Everything people are scared of, and what's actually true.

01
It's going to replace me.
In a year, the people who use this well will have replaced the people who don't. The tool itself isn't coming for you, the people behind it are.
02
It's going to lie to me.
It can be confidently wrong. Ask it to cite, or to tell you what it's unsure about. Claude is unusually good at saying 'I don't actually know' when you invite it to.
03
I'll break something.
You can't. A chat is a sandbox. Type something, regret it, start over. You've never had a workspace this forgiving.
04
I'm not technical enough.
Nothing about Claude requires a single line of code. It's a chat window. If you can text a friend, you can use it.
05
I don't know where to start.
You do. Ask it the next real question on your mind. Whatever it is. That's the start.
06
It's too late.
You're roughly 18 months in on a 20-year curve. You are extremely early. Stop reading and open the tab.
Lesson 06 · 1 min

Your first 7 days

Do these in order, at whatever pace feels right. None takes more than 10 minutes. By the end of a week you will have the feel for it.

Lesson 07 · 1 min

Where to go from here

Three doors. Walk through whichever one is yours.

I don't think of Claude as a tool. I think of it as a second set of hands for the life you already have. It's only as good as the questions you bring it, and your questions are already better than you think.

Start small. Be blunt with it. Tell it when it's wrong. Ask it to try again. Treat it the way you'd want to be treated on your first day at a new job, and it will return the favor.
