If you have never opened one and don't know where to start
No prior knowledge assumed, no jargon, and one job to try this week.
Nothing about this is obvious
A blank box with a cursor in it is genuinely bad design for a first-time user. It offers no clue about what it is for, what it is good at, or what it will do badly, and then it answers anything you type with total confidence. People who find it useful are not cleverer than you. They have usually just tried it against the same job about thirty times.
The mental model that helps
Treat it as a very fast, very widely read assistant on their first morning at your business. They write well, they have read an enormous amount, they will never say they are unsure, and they know nothing whatsoever about your clients, your obligations, your house style or the thing everyone in your office knows not to do.
Everything that follows comes out of that one picture. You would not hand a first-morning assistant an unexplained task and send the result straight to a client. You would tell them who it is for, what it must not say, and what good looks like, and you would read it before it went out. That is the entire skill. The rest is practice.
Start with one job, not with the tool
The usual failure is opening a tool and hunting for something to use it on. Reverse it. Take one job you already do most weeks that annoys you, that involves no client information, and where you would recognise a good answer immediately. An internal update. A first draft of a standard reply. A messy page of notes that needs a structure.
Do it three times across a week. Not thirty jobs once each, which teaches you nothing, but one job three times, which teaches you exactly where the tool is strong and where it quietly invents.
What good looks like
A useful instruction is boring and long. It says who the reader is, what you want at the end, what must not appear, roughly how long it should be, and what you are going to do with it. Four or five sentences of that produces a different class of answer from a single line, and the difference is not subtle.
The worked version of this, with the before and after side by side, is getting output you can actually use.
What to ignore for now
Agents, automations, plug-ins, model release news and anything promising to run your business while you sleep. None of it matters until you can reliably get one page of usable text out of one tool. Ignoring all of it costs you nothing; chasing it is the most common way people conclude the whole category is nonsense.
The one thing to learn before anything else
What never goes in. There is a short list of information that does not belong in a general-purpose AI tool regardless of how careful you are being, and the damage is done by people who did not know the list existed rather than by people ignoring it. Read what never goes in an AI tool before your first real attempt, not after.
The questions we get asked about this
Will I be the only one in the room who has never used it?
Very unlikely. The normal room is roughly half people who have barely touched it, and the half who have are usually doing one narrow thing repeatedly rather than anything sophisticated.
Do I need to be good with computers?
No. If you can write an email describing what you want to someone competent who has never met your business, you have the skill. The hard part is being specific, and that is a writing problem rather than a technical one.
Do I have to pay for a subscription to start?
No, and we will tell you when the free version is enough. The free and paid tiers differ in what happens to your information as well as in capability, which is covered before anyone signs up to anything.
How long before it is useful rather than a novelty?
For one narrow job you do repeatedly, usually the same sitting. The gap between novelty and use is almost always specificity: telling it who the reader is, what the constraint is, and what a good answer looks like.
The other three
Same session, different starting point. If you think this is about replacing you. If you are already using it and nobody asked you to. If you are the one who has to decide.
