ChatGPT explained: what it is, what it costs, how to start

If you’ve heard one AI name, it’s this one. ChatGPT is the chatbot that made all of this famous, and for most people it’s still the sensible place to start. Here’s a plain description — no hype, no warnings in capital letters.

What it is

ChatGPT is a website (and an app for phones) where you type a message and get a written answer. It’s made by a company called OpenAI. “GPT” is the name of the engine underneath; the “Chat” part is what you see.

You can ask it questions, ask it to write things, ask it to explain things, or just talk to it. It replies in full sentences, in whatever language you write in, and it remembers what you said earlier in the same conversation.

It is not a person. It is not connected to your computer. It cannot see your screen or your files unless you paste them in. It’s a very good text-generating machine with a friendly manner. (How it “knows” things.)

What it costs

There is a free version, and it’s good. You go to chatgpt.com and you can use it. For most everyday purposes — letters, explanations, recipes, questions — the free version is all you need. You may hit a limit if you use it heavily in one sitting; it tells you, and it resets after a while.

There are paid versions. The main one, called Plus, costs roughly what a streaming service does per month; in some countries there is also a cheaper tier called Go. You get a more capable engine, fewer limits, and some extra features. The exact price and what’s included change from time to time, so check the website rather than trusting a number here.

Should you pay? Not to start with. Use the free version for a month. If you find yourself hitting limits or wishing it were cleverer, you’ll know. Most people we’d write this site for will never need to.

Do you need an account?

You can try it without one. But making a free account — email address and a password — is worth it: your conversations are saved, so you can go back to that letter draft tomorrow. Making an account is the one moment to be careful: use a password you don’t use anywhere else, and never type your password into the chat itself.

How to start, in five steps

1. Open your web browser and go to chatgpt.com.
2. You’ll see a box at the bottom that says something like “Ask anything.” Click in it.
3. Type a question, as you’d ask a person. Try: “Explain in simple terms how a fridge keeps things cold.”
4. Press Enter (or the arrow button). Read the answer.
5. Type a follow-up in the same box: “Shorter, please.” or “Why does it hum?”

That’s the whole thing. There’s nothing to install and nothing to configure. If you’d like a slower walk-through with reassurance at each step, we have one.

What the buttons do

You don’t need most of them. The three worth knowing:

• “New chat” (top left): starts a fresh conversation. Use it when you change subject.
• The list on the left: your previous conversations. Click one to continue it.
• The paperclip or “+” near the typing box: attach a photo or file to ask about. Handy for “what does this letter say?” — with the personal details blanked out.

Everything else — voice, image creation, “projects,” the settings — you can explore when you’re curious. None of it is required.

Three things it’s especially good for

Drafting. Any letter, email or message you’d rather not write from scratch. (Guide here.)

Explaining. “Explain this like I’m not a doctor.” “What does this word mean?” “Why is the sky blue, but properly?”

Thinking out loud. Gift ideas, what to ask at an appointment, how to say something awkward. It’s a patient sounding board that never gets bored.

Three things to remember

It can be wrong, confidently. Check anything that matters — names, dates, numbers, medical or legal facts. (Why.)

It can be out of date. The free version may not know about recent events. If it can search the web, it’ll show links; if it doesn’t, assume it’s working from memory.

What you type is stored. Not read by a person, usually — but stored. Keep passwords, ID numbers and other people’s private details out of it. There’s a setting to stop your chats being used for training; here’s how to find it.

Is it the right one for you?

ChatGPT is the most widely used and the most polished. Google’s Gemini is very similar and may already be on your phone. Microsoft’s Copilot is built into Windows. They can all do the same everyday jobs. Pick one, get comfortable, and don’t feel you have to try them all. This one is a fine place to start.
