Lesson 3 · about 10 min

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:

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:

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:

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:

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.

Knowledge check

  1. You want a thank-you note for a coworker who covered your shift. Which opening gives the model the most to work with?
  2. The model's first answer is close but too long and a little stiff. What is the best next move?
  3. Why does adding "Here is an example of the style I want:" and pasting a short sample help?
  4. You need to plan a family reunion: guest list, budget, venue, food, and a schedule. What is the better approach?
