Reading about prompts is useless until you feel the difference. Five minutes — do it now, properly.
The task
Open any AI chat you already use — ChatGPT, Claude, Gemini, or Gertrude on this site.
Step 1 — Send the weak prompt
Copy this exactly:
Write an email about a late payment.
Read the reply. It's fine. It's also probably generic and a bit limp.
Step 2 — Send the upgraded prompt
Now copy this:
You are a small-business owner in the UK. Write a short email to a customer who is 2 weeks late paying an invoice for tattoo work. Tone: firm but polite, not threatening. Under 120 words. End with a clear next step (how to pay). Do not invent account numbers or legal threats.
Read the new reply.
You should see: a far more specific email — right length, right tone, fewer random inventions — because you handed it role, context, task, format and constraints.
That's the whole anatomy of a useful prompt. We practise it properly in later lessons; today you only need to clock one thing: you steered the pattern. Same app, better instructions.
This was my own first "oh — that's how it works" moment. Not a new model, not a fancier subscription tier. Same tool, sharper instructions. I still rewrite a prompt twice when something actually matters.
Optional stretch
Change one line of the upgraded prompt — the industry, the tone, or the word limit — and send it again. Watch exactly what moves.
Continue once you've tried both prompts (or you're happy you've got the idea).
