How to use ChatGPT: a practical guide
How to use ChatGPT without the hype: what it does well, where it fails, and the four part prompt that turns a vague answer into a usable draft.
How to use ChatGPT in the first five minutes
Open it, type what you want, read what comes back. That part needs no guide. The reason most first attempts disappoint is not the tool, it is that the request was three lines long and assumed the model could see things it cannot.
So treat the box as a brief rather than a search bar. It has no access to your files, your client or your last conversation unless you put them in front of it.
Free or paid: what actually changes
There is a free tier, and for most everyday text work it is enough: drafting, summarising, rewriting, explaining. No numbers appear here on purpose, because the limits and the model line up change often enough that any figure in an article goes stale.
Paid plans generally raise the limits and open newer models and more tools. If you are starting out, do not begin there. Find out first whether you actually hit the ceiling.
The four part prompt
Role, context, task, format. Who the model should be, what it can see, the one thing it should do, and what the answer should look like. This is the whole technique, and it survives every model update.
The single biggest improvement is pasting the real material instead of describing it. The second biggest is asking for one outcome per prompt.
You are my editor. Here is the draft: <paste> Task: cut it to 200 words without losing the argument. Keep my voice. Delete any sentence that only repeats the one before it. Return the edited text, then three lines on what you cut and why.
What it does well
The pattern is simple: it is strong wherever text goes in and text comes out, and weak wherever a single fact has to be right and you cannot check it.
Where it fails
Current facts, precise figures, legal detail and anything with an official local rule. It gets these wrong confidently, because a missing detail is filled with the most plausible continuation rather than an admission.
This is not carelessness you can prompt away. It is how the thing works, which is why the useful habit is to supply the facts rather than request them.
When to switch tools
When the job needs live data, use something with search. When it needs to act inside your own tools, that is what connections and protocols are for, not copy paste.

Common questions
What matters most when learning how to use ChatGPT?
Writing a brief instead of a search query. Everything else, the models, the settings, the plans, moves the result far less than giving it a role, the real context, one task and a format.
Is ChatGPT free to use?
There is a free tier that covers most everyday text work. The exact limits and the paid plans change from time to time, so check the provider's own page rather than an article.
Do I need to download anything to use ChatGPT?
Not in a browser. There are official mobile apps published by OpenAI, and the publisher name on the store listing is the thing to check before installing anything similar sounding.
Is ChatGPT the same thing as GPT?
No. GPT is the family of models and ChatGPT is the product built on them. The same model can behave differently in another product, because it is given different instructions and tools.
Can I use ChatGPT on work documents?
That depends on your employer's rules and the plan you are on, since data handling differs between tiers. Check the policy before pasting anything confidential, not after.
