Write a Better Brief for an AI First Draft

The idea in plain language

When an AI draft sounds generic, adding a dramatic instruction rarely helps. A clear brief does. OpenAI's own guidance is to be clear and specific, give enough context, and refine the prompt after reviewing the response.

A useful brief has five parts:

1. Goal: what the reader should understand or do.
2. Audience: who they are and what they already know.
3. Approved facts: only details you have confirmed, plus what is still undecided.
4. Format and tone: length, structure, and voice.
5. Boundaries: what it must not invent or promise.

Worked example

Write a short message to my two roommates proposing how we split shared monthly bills.
Audience: two roommates who already split rent equally but not utilities.
Goal: propose a simple way to split internet and electricity, and ask them to agree or suggest changes.
Approved facts: internet and electricity are the only shared bills; the amounts change each month; nothing is decided yet.
Format: one short paragraph, then one question.
Tone: friendly and plain. No pressure.
Boundaries: do not invent dollar amounts, due dates, payment apps, or rules we have not agreed. Keep it under 90 words.
After the draft, list the facts I must fill in before sending it.

Try it: revise once

1. Run the practice prompt in an AI tool you already use.
2. Point to one sentence that misses the brief and ask for a focused change, for example: “Make the second sentence shorter and remove the deadline.”
3. Try the same brief with a different tone. Keep the version that fits the reader, not the most enthusiastic one.

Check the result yourself

• The draft speaks to the audience I described.
• I can spot one clear purpose.
• It did not add amounts, dates, or rules that were not approved.
• I would say these words myself, or I edited them until I would.
• I listed the facts I still need before sending.

Limits of this lesson

• A fluent draft is still a draft. It does not prove any detail is correct.
• AI tools change often. Features and settings described in sources can differ in the tool you use.
• Use fictional or low-stakes examples first, and remove private details before pasting anything real. The privacy lesson covers how.
