It is a box you type into
Here is the entire thing, up front: ChatGPT is a box you type into, and something types back.
That is not a simplification for beginners. That really is the shape of it. Everything else on the screen exists to support that one exchange.
People arrive expecting something like a cockpit. They open it, see a mostly empty page with a single text box in the middle, and assume they must be on the wrong page or that something has failed to load. Nothing has failed. The emptiness is the design. You are meant to just start talking.
In plain English
- Prompt:
- Whatever you type into the message box. That is all the word means. You have been writing prompts your whole life without the label.
- Chat:
- One ongoing conversation, made up of everything you have typed and everything it has replied, kept together in one place.
- AI model:
- The thing doing the actual replying. ChatGPT is the app around it, a bit like how a phone is the thing you hold and the network is the thing carrying the call.
- Thread:
- Another word for one chat. If someone says start a new thread, they mean open a fresh conversation.
The four things on screen
The message box. Usually along the bottom, wide, waiting. You type into it and press enter or tap the arrow. There is no correct way to phrase things. Full sentences, half sentences, three words with a typo in them: it copes with all of it.
The conversation. Once you send something, your message and its reply stack up in the space above the box, oldest at the top, newest at the bottom, exactly like a text message conversation with a person. You scroll it the same way too.
The list of past chats. Off to one side, or tucked behind a menu button on a phone, sits a list of everything you have talked about before. Each one keeps its whole conversation, so you can reopen last Tuesday's chat and carry straight on. It usually names each chat for you based on what you discussed, which is why the list ends up full of slightly odd little titles.
The new chat button. Starts a blank conversation. This matters more than it sounds, and here is the rule of thumb: one chat per topic. Planning a holiday and rewriting your CV in the same conversation makes the answers muddier, because everything you have already said becomes background it is trying to honour. New subject, new chat.
If a conversation has gone sideways and you cannot rescue it, do not fight it. Start a new chat and ask again more clearly. It costs you nothing, and it is what experienced users do constantly.
You genuinely cannot break it
This is the part worth reading twice, because it is the thing that stops most people.
There is no wrong button. Nothing you type deletes anything, charges anything, or sends anything to anybody. If you write something nonsensical, it will politely try to help anyway. If you ask what you fear is a stupid question, it answers in exactly the same tone as any other question, because it has no capacity whatsoever to be unimpressed by you.
And no, there is not a person in an office somewhere watching your conversations scroll past. Your chats are stored on the company's systems, which is a real privacy consideration and exactly what lesson 6 is about, but nobody is reading over your shoulder in real time and nobody is judging your spelling.
ChatGPT is made by a company called OpenAI, and it is not the only one of its kind. Claude (from Anthropic) and Gemini (from Google) do broadly similar things with broadly similar screens. Learn one and you can walk into any of them. This course uses ChatGPT because it is the one most people meet first, not because it is the only option.
Try these three
Open it, type one of these, press enter. That is the whole exercise.
Explain what you are and what you are useful for, in plain English, as if I have never used anything like this before.
I want to understand what you are bad at. Give me three things people wrongly expect you to do well, and say why.
Ask me five questions about my week, one at a time, then suggest one thing I could hand over to you.
That third one is a small trick worth knowing early: you are allowed to ask it to ask you things. It does not only answer.
The empty screen is the hardest part of the whole tool. Once you have sent one message, the mystery evaporates and it becomes what it always was: typing to something patient.
Checkpoint
ChatGPT is one message box, one running conversation and a list of past ones, and nothing you type into it can break anything.
