How to talk to it (prompting)
The same tool gives a weak answer or a strong one, depending on how you ask. This Lesson is the part that pays off every time. A few habits turn a vague reply into one you can actually use.
Give it context
The model cannot see your situation. It only has your prompt — the words you type into the box. So tell it what a person helping you would need to know:
- Who you are: “I’m a parent,” “I run a small bakery,” “I’m new to this job.”
- The purpose: what the text is for and what you want it to achieve.
- The audience: who will read it — a landlord, a child, a hiring manager.
A prompt with context does not need to be long. It needs to answer “for whom, and why.”
State the form you want
Tell the model the shape of the answer, or it will pick one for you:
- Length: “three sentences,” “one paragraph,” “a short list.”
- Format: a list, a table, an email, bullet points.
- Tone: warm, plain, formal, direct.
If you do not say, you often get five paragraphs when you wanted three lines.
Show an example
If you have a sample of what you want, paste it in. Write “Here is the style I’m going for:” and add a short example. One example does more than a paragraph of description. The model is good at matching a pattern you hand it.
Treat the first answer as a draft
The first reply is a starting point. Read it, then say what to change, in the same chat:
- “Make it shorter.”
- “Drop the last paragraph.”
- “Say it more simply — my reader is 70 and not technical.”
The model keeps the earlier context, so each follow-up builds on it. This back and forth is normal and it is where most of the quality comes from.
Break a big ask into steps
For anything with several parts — a trip, a budget, a long document — do not ask for all of it at once. Ask for an outline first. Then work through one piece per message. Small answers are easier to check, and you catch a wrong turn before the model builds on it.
Point it at a role or a reader
Two short phrases — “act as” and “write for” — set the model’s point of view:
- “Act as a careful proofreader and mark what is unclear.”
- “Explain this like you are talking to a 10-year-old.”
- “Write this for someone who has never used a computer.”
This is a shortcut for setting tone and level without spelling out every rule.
Before and after: the same task, two prompts
The task: email your building manager about a leaking kitchen tap.
Lazy prompt:
Write an email about my sink.
You get a generic email. The model invents details it was never given — how long the tap has leaked, how bad it is, a unit number. You have to rewrite most of it.
Better prompt:
Write a short, polite email to my building manager. I’m in apartment 4B. The kitchen tap has dripped for three days and it’s getting worse. Ask them to send someone this week. Keep it to four sentences.
Now the email has your real details, the right length, a clear ask, and a tone you can send as is. Same tool, same task — the difference is entirely in the prompt.
Try it: prompt it badly, then improve it twice
Do all three of these in one chat, one message at a time. Watch the answer get closer to something you would actually send.
Round one — the lazy version:
Round two — add context and form:
Round three — reply to that answer with one fix:
Next, you will see the traps to watch for — the ways a confident answer can still lead you wrong.
