How to Write a Good AI Prompt: 6 Steps With Examples

Ask an AI tool to “write a product description” and you will get something generic. Ask it the right way and you will get something you can actually use. The difference is not the AI. It is the prompt.

This guide shows you how to write a good AI prompt in six simple steps, with before-and-after examples and a template you can copy. It works with ChatGPT, Claude, Gemini, Microsoft Copilot and any other AI chat tool. If you would rather answer a few questions than start from a blank page, the free Prompt Builder writes the prompt for you.

What Is an AI Prompt?

An AI prompt is the message you type into an AI chat tool such as ChatGPT, Claude, Gemini or Microsoft Copilot. It tells the AI what you want. The AI can only work with what is in your prompt, so the clearer and more complete it is, the closer the first answer will be to what you need.

The official prompting guides from the companies that make these tools agree on the basics: be clear and specific, give context, show examples, say what format you want and keep pasted material separate from your instructions. The six steps below put those basics into practice.

The 6 Parts of a Good AI Prompt

Part	What to include	Example
1. Goal	What you want, starting with an action word	Write a product description for our lavender candle
2. Background	Two or three real details about your situation	Hand-poured soy wax, burns for about 40 hours
3. Audience	Who will read or use the result	Online shoppers looking for a relaxing gift
4. Material	Notes, a draft, data or an example you like	Your current description or a sample you like
5. Result	Format, length and tone	Short paragraphs, about 100 words, warm and persuasive
6. Final touches	A role, must-haves and things to avoid	Act as a copywriter. Avoid exaggerated claims.

How to Write a Good AI Prompt in 6 Steps

Step 1

Start With a Clear Goal

Begin with an action word such as Write, Plan, Explain, Summarize, Compare or Fix, then say exactly what you want. Swap vague words like “something” or “stuff” for specifics, and if you want ideas, say how many.

Vague

Help with Instagram.

Better

Write an Instagram caption announcing our new pumpkin spice latte.

Step 2

Add Background Details

The AI knows nothing about you or your business. Two or three real details about your situation are the biggest upgrade you can make to any prompt.

Vague

Write a product description for my candle.

Better

Write a product description for our handmade lavender soy candle for our online store. Example Company is a small, family-owned candle shop. The candle is hand-poured soy wax, burns for about 40 hours and comes in a reusable glass jar.

Step 3

Say Who It Is For

Naming the reader changes the words, detail and tone the AI uses. A busy customer, a hiring manager and a complete beginner all need different answers.

Vague

Explain how a credit score works.

Better

Explain how a credit score works for a complete beginner who just got their first credit card.

Step 4

Share Your Material

Real material beats a description of it. Paste your notes, draft, data, an error message or an example of the style you like. Put pasted content between clear markers, such as <material> tags, so the AI can tell it apart from your instructions. Remove passwords, account numbers and private details before you paste anything.

Step 5

Describe the Result You Want

Say the format (paragraphs, bullet points, a table, an email), the length (for example, about 100 words) and the tone (for example, friendly and professional). Describing the finished result up front saves you from asking the AI to redo it.

Step 6

Add Final Touches

Give the AI a role, such as “an experienced copywriter” or “a patient teacher,” to set its point of view. List anything it must include and anything to avoid. Then add one or two instructions that improve the answer, like asking it to say when it is unsure.

Before and After: A Complete Prompt

Here is a one-line request and the same request written with all six parts. The second one was made with the Prompt Builder.

Vague prompt

Write a description for my candle.

Complete prompt

You are an experienced copywriter.

## My goal
Write a product description for our handmade lavender soy candle for our online store.

## Background
Example Company is a small, family-owned candle shop. The candle is hand-poured soy wax, burns for about 40 hours and comes in a reusable glass jar.
Audience: Online shoppers looking for a relaxing gift.

## What I want back
- Format: clear, well-organized paragraphs
- Length: Keep it short, about 100 words.
- Tone: warm and persuasive
- Must include: the scent, burn time and reusable jar
- Avoid: exaggerated claims

## How to respond
- If you are unsure about something or do not have enough information, say so instead of guessing.

The AI now knows the real product details, who is buying, what to highlight, what to avoid and how long it should be.

Copy-and-Paste AI Prompt Template

Replace the text in square brackets, delete any section you do not need, then paste it into your AI tool.

Template

You are [a role, such as an experienced copywriter].

## My goal
[What you want, starting with an action word.]

## Background
[Two or three real details about your situation.]
Audience: [Who it is for.]

6 Instructions That Lead to Better Answers

Add any of these lines to the end of your prompt. They are the same “better-answer boosters” you can switch on in the Prompt Builder.

Add this line	When it helps
“If you are unsure about something or do not have enough information, say so instead of guessing.”	Any time facts matter
“Before you begin, ask me any questions you need answered to do this well, then wait for my reply.”	Bigger tasks where you may have left something out
“Think through the problem step by step before giving your final answer.”	Reasoning, math, comparisons and decisions
“Give me 3 different versions to choose from.”	Captions, headlines, names and anything that comes down to taste
“Use plain, everyday language and avoid jargon.”	Explanations for beginners, customers or kids
“Point out any facts, numbers or claims I should double-check before using them.”	Research, numbers, health, money and legal topics

These instructions help, but no prompt guarantees a correct answer. Always check important facts before you use them.

Follow-Up Prompts to Improve the Answer

Treat the first answer as a starting point. After the AI replies, send one of these:

• Check your answer against everything I asked for and fix anything that is missing.
• Make it shorter and clearer without losing the key points.
• Give me two other versions with a different approach so I can compare.
• What assumptions did you make? List them so I can correct any that are wrong.
• What would make this better? Ask me anything you need to know.

Common AI Prompt Mistakes to Avoid

• Being too vague. “Help with marketing” leaves the AI guessing. Say exactly what you want.
• Leaving out your situation. Without background, the AI writes for an average business, not yours.
• Describing instead of pasting. Share the actual draft, notes or data whenever you can.
• Forgetting the format. Say whether you want an email, a list, a table or paragraphs.
• Pasting private information. Remove passwords, account numbers and personal details first.
• Trusting every answer. AI can sound confident and still be wrong. Check facts, numbers and quotes.

Frequently Asked Questions

What is an AI prompt?

An AI prompt is the message you type into an AI chat tool such as ChatGPT, Claude, Gemini or Microsoft Copilot. It tells the AI what you want. The clearer and more complete the prompt, the less you need to correct the answer.

What makes a good AI prompt?

A good prompt has a clear goal that starts with an action word, background details about your situation, who the result is for, any material the AI should work with, the format, length and tone you want, and anything it must include or avoid.

Do the same prompts work in ChatGPT, Claude, Gemini and Copilot?

Yes. The basics are the same in every AI chat tool: be clear and specific, give context, share examples and say what format you want. A well-written prompt works in any of them, although each tool may answer a little differently.

How long should an AI prompt be?

As long as it needs to be to include the important details. A one-line prompt often leads to a generic answer. Two or three real details about your situation usually make the biggest difference.

Why give the AI a role?

Telling the AI to act as, for example, an experienced copywriter or a patient teacher sets its point of view, vocabulary and level of detail.

How do I get fewer made-up answers from AI?

Paste real material for the AI to work from, ask it to say when it is unsure instead of guessing, and ask it to point out facts you should double-check. These help, but no prompt guarantees accurate answers, so always check important facts, numbers and quotes.

Is there a free tool that writes AI prompts for me?

Yes. The free Prompt Builder asks you six simple questions and turns your answers into a clear, well-structured prompt you can copy into ChatGPT, Claude, Gemini or Copilot. It runs in your browser, never connects to an AI and never stores what you type.
