Understanding prompts: how to ask AI for what you want

The four parts of a good prompt, before-and-after examples, and follow-ups.

The short version

A prompt is simply what you type (or say) to an AI tool. Good prompts have four parts: the task (what you want), context (who it’s for and why), details (anything it must include or avoid) and the format (a list, a short email, a table). Then keep going with follow-ups.

📅 Checked as of October 2026. Apps and rules change, so check the sources below if something looks different.

1. What is a prompt?

A prompt is your question or request. AI tools can't read your mind: the more clearly you say what you want, the better the answer. You don't need special words; plain English works best.

Think of it like this: it's like giving directions to a taxi driver. “Take me somewhere nice” gets you somewhere; “the Italian place on Main Street, by 7, the quick way” gets you where you wanted to go.

2. The four parts of a good prompt

  1. Task: what you want it to do. “Write”, “explain”, “plan”, “compare”, “summarize”.
  2. Context: who it's for and why. “For my grandson's 10th birthday”, “I'm a beginner”.
  3. Details: must-haves and must-avoids. “Under $50”, “no nuts”, “keep it friendly”.
  4. Format: how the answer should look. “5 bullet points”, “a short email”, “a table”.

3. Before and after

🙁 Before “Write a birthday message.”

😊 After “Write a warm, funny birthday message for my sister Ann, who's turning 60 and loves gardening. Keep it under 50 words.”

Adds context (who, age, interests) and format (length).

🙁 Before “Plan a trip.”

😊 After “Plan a relaxed 3-day trip to San Diego for two retirees who don't like long walks. Give a simple day-by-day list with one main activity per day.”

Adds context, a detail to avoid, and a format.

🙁 Before “Explain the cloud.”

😊 After “Explain what “the cloud” means in plain English for someone who has never used it, in 3 short bullet points, with one everyday example.”

Adds the audience and the format.

4. Ask follow-ups

The first answer is a starting point. Just reply in the same chat:

  • “Make it shorter.” / “Make it more formal.”
  • “Give me 3 other options.”
  • “Explain step 2 more simply.”
  • “What are you unsure about? What should I double-check?”

Start a new chat when you switch topics, so old details don't get mixed in.

⚠️ Don't put passwords, card numbers, ID numbers or medical records in a prompt.
