Lesson 2 of 7 · 15 min · Checked on 6 October 2026

Your first conversation: asking well

By the end of this lesson you will be able to:

  • Write a complete request with the formula situation + what you want + who it is for + format + example
  • Ask the AI to question you before it answers
  • Improve an answer with short follow-ups such as "shorter" or "more formal"

Two requests, two answers

Fátima needs a residence certificate. She wants to ask the junta de freguesia (the parish council), by email, which documents she has to bring. She opens an AI assistant and types her first request. Then she tries a second one. See the difference:

Bad request Good request
"write an email to the junta" "I live in the parish and I need a residence certificate to hand in at my daughter's school. Write a short, polite email to the junta de freguesia asking which documents I have to bring, what the opening hours are and whether I can arrange it by email. Formal but simple tone, maximum 8 lines. End it with '[SIGNATURE]', which I will replace with my name later."

With the bad request, the AI has to guess everything. You get a generic email, with three paragraphs of politeness and nothing concrete. With the good request, you get an email Fátima can send almost untouched: she only swaps the label for her name.

The AI is not lazy or stubborn. It just does not know what you have not told it.

The formula: five pieces

A good request has, in this order:

  1. Situation — what is going on. "I live in the parish and I need a residence certificate."
  2. What you want — the task, with a clear verb. "Write an email asking…"
  3. Who it is for — who will read it. "For the parish council." It changes the tone: you do not write the same way to a friend and to an authority.
  4. Format — length and shape. "Maximum 8 lines." "As a list." "In European Portuguese."
  5. Example (if you have one) — a similar text you liked. "Write in this style: …"

You do not always need all five. But the more pieces you give, the less the AI has to guess.

Here is Fátima's request, ready to copy. Replace what is in [square brackets], except the label [SIGNATURE]: leave that one exactly as it is. You only write your name later, in the email, outside the AI.

I live in the parish of [name of parish] and I need a residence certificate for [what it is for]. Write a short, polite email to the junta de freguesia asking which documents I have to bring, what the opening hours are and whether I can deal with it by email. Formal but simple tone, maximum 8 lines, in European Portuguese. End it with "[SIGNATURE]", which I will replace with my name later.

Tip

Always say which language you want. If the email is for an office in Portugal, write "in European Portuguese". Many assistants answer in Brazilian Portuguese by default ("você", "celular", "ônibus"). You only need to ask once, at the start of the conversation. If you do not read Portuguese well, ask for an English version underneath, so you know what you are about to send.

Let the AI ask you questions

Sometimes you do not know what needs to be said. Then ask the AI to question you first. Add this sentence at the end of any request:

Before you write, ask me up to 3 questions about what you still need to know. Only then write.

The AI might ask, for example, "Is this the first time you are asking for this certificate?" or "Would you rather collect the document at the counter or receive it by email?" You answer, and the final text comes out much closer to what you need.

Fine-tuning: the conversation goes on

The first answer is rarely the final one. Do not start again from zero. Reply in the same conversation, with short follow-ups:

Shorter, maximum 5 lines.
More formal. Address the president of the junta as "Exmo. Senhor Presidente".

Others that work: "Remove the last paragraph." "Give me three suggestions for the email subject line." "Explain what you changed." This is called iterating: improving little by little.

Watch out

Do not put your Citizen Card number, tax number (NIF) or other personal data in the request. To write the email, the AI does not need them: you fill them in yourself at the end. Lesson 5 explains why. And always read the text before you send it. You are the one signing.

Where and how to use it, today

This is how it looks on 6 October 2026; your screen may differ.

  • On the computer: open the browser (Chrome, Edge, Firefox, Safari) and type the address of the assistant. Lesson 4 has the list. Type your request in the text box at the bottom and press Enter.
  • On the phone: install the official app from your phone's store (Play Store or App Store). Check that the name of the company that publishes it is the real one.
  • By voice: phone apps usually have a button with a microphone. Press it, speak, and what you said appears as text. Some also have a voice conversation mode, in which the AI answers out loud. It is very handy if you do not like typing on a small screen.

Normally, the service asks you to create an account with your email. There are free versions and paid versions. To start, the free one is enough. For prices and differences, see the Current state page.

Each service also has a minimum age in its terms of use, and sometimes it requires a parent's permission for minors. If you are a parent or grandparent, check before letting a child use it.

Tip

Keep the requests that worked well in a notepad. Next time, you only change the details. After a few weeks you have your own collection.

Exercise

How I know it worked an email of 5 to 10 lines, polite and concrete, that you could send today once you have replaced [SIGNATURE] with your name, outside the AI.

If it didn't work

  • Did the answer come out generic? Check whether you gave the situation, who it is for and the format. One of these pieces is almost always missing.
  • Did it come out in Brazilian Portuguese? Write "Rewrite in European Portuguese".
  • Did the AI skip the questions and write straight away? Tell it: "Stop. First ask me the questions, then write."
  • Cannot find where to type? Look for a text box at the bottom, with a phrase such as "Write a message" or similar.

Test what you learned

1. You want to ask the school for the schedule of parent-teacher meetings. Which is the best request for the AI?
2. The AI wrote you an email, but it came out long and full of ceremony. What do you do?
3. You are about to ask for help with a text, but you are not sure which details to include. What is the best way to start?

Corrections to this lesson (1)
  • : After an external review: the request to copy no longer tells you to type your name into the AI; it uses the label [SIGNATURE], which you replace with your name later, outside the AI (as the warning about personal data asks); the quiz example no longer has people's names; the quiz options were reordered.
