CLAUDE FOR DUMMIES

98.75% of people have never tried Claude. Not even once. And most don't know what they're missing.

I made a super basic guide to bridge that gap. Claude for Dummies. If you already use it, skip to the end. If not, read this.

Most likely, you haven't tried it because:

You don't use AI.

You only trust ChatGPT.

Or (worst of all), you only use the free version of ChatGPT.

I promise this will change your perspective. I'll assume you have no idea. By the time you finish, you'll know more than 99% of people. Sound good? Let's begin.

First of all, two things: Save this post. And send it to that friend who still thinks Claude is just some guy's name.

1. What is this Claude thing?

Basically, it's another AI you can chat with. You ask it for things, it does them. It writes, summarizes, analyzes heavy documents, and even creates a 12-tab Excel sheet with real formulas without blinking.

It was made by a company called Anthropic.

You'll save yourself headaches if you understand this:

• Autocomplete on steroids: Claude doesn't "think" like you do.

It predicts the next word billions of times. That's why it sometimes sounds super confident... even when it's making things up.

• The "yes, boss" syndrome:

It's programmed to be helpful and agree with you. If you say something silly, it will validate it. You are at the helm.

• Tokens: It reads and writes in "blocks" (tokens).

A token is roughly a word. Chats have a limit. If a chat gets too long, Claude will start saying nonsense because its memory is full. Solution: open a new one.

2. Claude vs. ChatGPT: What's the difference?

They are the same species, but with different personalities.

Where Claude wins by a landslide:

• When writing, it sounds much less like a "corporate robot."

• It can read a 200-page PDF in one go without losing the thread.

• If you use the desktop app, it directly accesses files on your computer.

Where ChatGPT is still king:

• Voice mode is from another galaxy.

• It generates images.

• It searches the internet a bit faster.

✓ Tip: You don't have to marry one. Use Claude for writing and processing long things, and ChatGPT for voice, images, and speed. (Note: the paid version of either is INFINITELY better than the free one).

3. How to get Claude (and what it costs)

Go to claude.ai

• Free: To poke around for a couple of weeks. Limited messages.

• Pro ($20/ 15 EUR per month): The sweet spot. You get the best model (Opus), Cowork, and access to your files.

• Max ($100 or $200 per month): For people who live inside AI and hit the Pro ceiling.

(There are Team and Enterprise plans for large organizations).

My rule for choosing:

Free if you're still doubting. Pro if you'll use it more than 3 times a week. Max if Pro is always falling short.

✓ Tip: Pay monthly, not annually. Try it for 30 days. If by week 3 you haven't opened it, cancel. You've lost $20, not $240.

4. The 3 "Claudes" that exist

This confuses everyone at first:

The classic chat. Start here if it's your first time. In the browser (claude.ai)

On the computer (Mac/Windows App). Same, but this is where Claude can "see" your local folders and you unlock Cowork mode.

3. Cowork (Pro mode). This is something else. You give it a task (e.g., "organize these 40 invoices and make me an Excel") and it works on its own for 15 minutes while you go get a coffee. When you return, the work is done in your folder. It's pure magic and only in the paid app.

5. How to talk to it so it doesn't sound like a robot

If you've never written a prompt, this is for you:

Rule 1: Be specific. Don't say "write an email." Say "write an email to Sara, friendly but firm, 4 lines long."

Rule 2: Give examples. This works best. Paste something of yours and say "write like this for me." Claude learns faster from examples than from instructions.

Rule 3: Say what you want, not what you DON'T want. "Don't sound formal" is worse than "sound like you're talking to a colleague on Slack."

Rule 4: Start small. Don't write a massive block. Write two sentences, see what comes out, and adjust. It's a chat.

Rule 5: If it goes crazy, change chats. Don't insist. Open a clean one and paste the important stuff. A new beginning is free.

⚠ Careful. Claude will ALWAYS give you an answer.

It doesn't mean it's correct. Treat it as a partner, not as absolute truth.

6. What it's a pro at and where it fails

It's good for:

• Writing and adapting to your voice.

• Summarizing very long documents without losing the thread.

• Acting as a "thinking partner" (as long as you challenge its ideas).

• Working with your local files.

It's bad for:

• Real-time information (you need to activate web search).

• Precise math (it's not a calculator).

• Generating images (use ChatGPT or Gemini for that).

⚠ The most common error: Vague requests assuming it's a god. No. It's your best employee, but it needs direction from a boss: YOU.

7. The 3 words that matter

If you learn this, you'll use Claude better than 90% of the people who pay for it:

Token: The unit it thinks in. If Claude gets silly after a long chat, it's because it's full.

Cowork: Claude working for you on your computer for minutes or hours. It does the real work while you do something else.

Claude Code: Claude for programmers. If you don't write code, ignore it. Cowork does 80% of this for non-devs.

8. 10 things to try this week

Choose 3. Each one teaches you something different:

Paste 3 of your posts. Ask for 3 new ones in your same voice.

Upload a 50-page PDF. Ask for a 1-page summary with references.

Paste meeting notes. Ask who does what.

Set Cowork to "Downloads." Ask what you can delete.

Paste a chaotic email thread. Ask for the next 3 actions.

Connect Gmail and repeat the above without pasting anything.

Give it a Doc of yours. Ask it to improve it, explaining why.

Give it an Excel. Ask what patterns it sees that you missed.

Paste a competitor's website. Ask it to compare.

Give it your calendar. Ask which meetings to say "no" to.

✓ Tip: Save a file called "prompts-that-worked." In 2 weeks you'll have a personal library worth more than any pack you can buy.

Your test drive

You don't have to delete ChatGPT. Choose a path tonight:

. Paste a text of yours and ask it to improve it. Do the same in ChatGPT. Compare. (Keep in mind that with the free version you'll hit the limit quickly.) The Free path: Go to claude.ai

The Cowork path ($20 for 1 month): Pay for Pro, download the app, open Cowork, point it to a folder full of documents and say: "Look at this and suggest 3 useful things you could do." Watch. Don't write anymore. Let it work.

If after this you don't see the magic, cancel Pro, no hard feelings. But don't be one of those who read this, feel smart for 20 minutes, and never open the app. Be part of the 1.25% who actually try it.

Words you can ignore (for now)

You'll see these words everywhere. They don't matter until you use Claude daily. But here's what they mean in simple words, so you stop wondering:

Projects. A folder inside Claude that remembers context between chats. Useful when you repeat the same type of work.

Artifacts. The side panel where Claude opens documents, code, or mini-apps it creates for you. You'll recognize it as soon as you see it.

Skills. Reusable prompts (instructions) you activate by name within Cowork or Chat. Think of them as saved workflows. For example: /negotiation.

Connectors. How Claude communicates with Slack, Gmail, Google Drive, Granola, Notion. You configure them when you need them. It extracts info from your apps.

MCP. It's very technical, but basically, it's the way to connect things to Claude (Connectors are MCPs, for example). But you'll never have to touch any of this.

Plugins. Packages of Skills and Connectors for Cowork. Like a small app store.
