How to Write Your First Good Prompt

A good prompt is a clear request: what you want, for whom, with what material and in what shape. This guide walks you through writing your first one step by step, with examples you can copy and adapt, so you stop getting vague answers and start getting useful ones.

What you will learn

• The five parts of a clear prompt.
• How to fix a vague prompt in under two minutes.
• How to improve a result with follow-up messages instead of starting again.

Time: 15 minutes. Level: Beginner. You need: access to any AI assistant, such as ChatGPT, Claude or Gemini.

Why prompts matter

An AI assistant cannot read your mind. It only knows what is in your message and the conversation. If you write “Help me with my shop”, it has to guess what you mean. If you write who the audience is, what the goal is and what the answer should look like, it can do a much better job.

Step 1: Start with one clear task

Begin with a specific action word such as write, summarise, compare, list, explain, rewrite or plan. Say what the output is.

Step 2: Add the context the AI cannot guess

Tell it who the audience is, what the goal is and any background. Include the material to work with, such as the text to rewrite or the notes to summarise.

Audience: first-time buyers aged 25 to 40
Goal: get them to add the candle to their basket
Background: hand-poured soy wax, 40-hour burn time, three scents

Step 3: Set constraints

Constraints stop the answer from being too long, too formal or off-topic. Common ones are length, tone, reading level, things to include and things to avoid.

Constraints: under 80 words, friendly tone, no exaggerated claims, do not mention price

Step 4: Choose the output format

Say how you want the answer: a short paragraph, bullet points, a table, an email with a subject line, or a numbered plan. If you will paste the result somewhere, ask for that exact format.

Step 5: Review and refine

Read the answer critically. Then reply with specific changes, such as “make it shorter”, “use a more formal tone” or “add one example”. This is faster than starting again and keeps the context.

Putting it together

Write a product description for a handmade soy candle.
Audience: first-time buyers aged 25 to 40. Goal: get them to add it to their basket.
Details: hand-poured soy wax, 40-hour burn time, three scents (lavender, cedar, citrus).
Constraints: under 80 words, friendly tone, no exaggerated claims, do not mention price.
Format: one short paragraph followed by three bullet points for the scents.

Common mistakes

• Too vague: “Make it better” does not say better how. Name what to improve.
• Too much at once: split big tasks into steps.
• No source material: paste the text rather than describing it.
• Trusting the first answer: always check facts, names and numbers.
• Sharing private data: do not paste passwords, ID numbers or confidential information.

Checklist before you press send

• Is there one clear task?
• Did I say who it is for and why?
• Did I include the material to work with?
• Did I set length, tone or other limits?
• Did I say what format I want?

Frequently asked questions

Do I need to use special words?

No. Plain language works best. Clarity matters more than clever wording.

Should I write long prompts?

Long enough to be clear, short enough to stay focused. A few well-chosen sentences usually beat a page of rambling.

Why does the same prompt give different answers?

AI responses vary between runs. If you need consistency, give a clear format and an example.
