How to Write AI Prompts: A Beginner’s Guide for ChatGPT, Gemini and Claude

A good AI prompt tells the assistant four things: who it should act as, the task, your context, and the format you want back. Be specific, include the details only you know, and improve the answer with follow-up messages instead of starting over. This works the same way in ChatGPT, Gemini, Claude and most other assistants.

What is a prompt?

A prompt is the message you give an AI assistant. OpenAI describes prompt engineering as designing and refining prompts to guide a model’s responses, and its first tip is to be clear, specific and give enough context (OpenAI Help Center). You do not need special words or code. You need to say what you want as clearly as you would to a capable new colleague who knows nothing about your situation.

The four parts of a good prompt

• Role: who the assistant should act as. "Act as an HR manager reviewing CVs."
• Task: the job, in one clear sentence. "Improve my CV summary."
• Context: what only you know. "I am a fresh BS Computer Science graduate applying for junior support roles in Lahore."
• Format: what the answer should look like. "Give three versions under 60 words each."

You will not need all four every time. A quick question can be one line. But when an answer disappoints you, the missing piece is almost always context or format.

What do the AI companies themselves recommend?

The advice in this guide is not a trick of one tool. The three biggest AI companies say much the same thing in their own guides:

Google’s four areas match the role, task, context and format parts above almost word for word. Learn them once and they work in every assistant.

Before and after: three everyday examples

An email to your landlord

Before: "Write an email about my broken geyser."

After: "Write a short, polite email to my landlord. The geyser in my flat stopped working four days ago and I reported it on WhatsApp on Monday. I want a repair date this week. Keep it firm but friendly, under 120 words."

A reply to a customer

Before: "Reply to this complaint."

After: "I run a small clothing shop that sells on Instagram. A customer says her parcel arrived late and the colour was wrong. Here is her message: [paste]. Write a reply that apologises, offers an exchange, and asks for her order number. Warm tone, three sentences."

A study explanation

Before: "Explain photosynthesis."

After: "Explain photosynthesis to a Class 9 student in simple English. Use one everyday example, then give me three short questions to test myself, with answers at the end."

Prompts for work: three more examples

An Upwork or Fiverr proposal

"I am a freelance [skill] with [experience]. Here is the job post: [paste]. Write a proposal under 150 words that opens with the client’s main problem, shows one relevant example of my work, and ends with one question about the project. No generic greetings."

A spreadsheet formula

"In Google Sheets, column A has order dates and column C has amounts in PKR. Write a formula that totals the amounts for September 2026 only. Explain each part in one line so I can adjust it." Test it on a copy of your sheet first.

A reply in Roman Urdu

"Reply to this customer in the same Roman Urdu style she used. Confirm her order of two kurtas, delivery in 3 to 5 days, cash on delivery. Keep it warm and under 50 words. Message: [paste]." Read it before you send it: AI replies in Roman Urdu can sound stiff or get a word wrong.

Fix weak answers with follow-ups

The first answer is a draft. Instead of rewriting your whole prompt, tell the assistant what to change. OpenAI’s own tips recommend starting with a prompt, reviewing the result and adjusting from there (OpenAI Help Center). Useful follow-ups:

• "Shorter. Keep only the three most important points."
• "Make it sound less formal, like a message to a colleague."
• "You missed the deadline I mentioned. Add it."
• "Give me two different versions so I can choose."
• "What questions would you need answered to do this better?"

The last one is underrated. Asking the assistant to interview you often surfaces the context you forgot to give.

Three techniques that make a big difference

1. Show an example. Paste a message you liked and say "match this style". Examples beat descriptions.
2. Set limits. Word counts, bullet points, reading level and what to leave out all sharpen the result.
3. Allow "I don’t know". Adding "If you are not sure, say so" makes invented answers less likely.

The third one matters because assistants can state wrong things confidently. Better prompts reduce errors but do not remove them, so learn how to fact-check an AI answer before you rely on anything important.

Prompt templates you can copy

Fill in the brackets and paste. Each template already carries the role, task, context and format, so you only add your details.

Common prompting mistakes

• Being vague: "make it better" gives the assistant nothing to aim at.
• Hiding the goal: say what the text is for and who will read it.
• Asking for five things at once: split big jobs into steps.
• Accepting the first answer: one or two follow-ups usually improve it a lot.
• Pasting private data: CNIC numbers, bank details and other people’s information do not belong in a chatbot.

Save the prompts you reuse

Once a prompt works, keep it. A notes file is fine to start. You can also build it into the assistant. Projects in ChatGPT keep chats, files and instructions together (OpenAI Help Center). Claude Projects do the same, and free users can create up to five (Claude Help Center). In Gemini, a Gem is a saved assistant with your own instructions (Gemini Apps Help).

The same four parts help when you use AI to learn. See how to use AI for studying without cheating for prompts built for students.

Practise on real tasks

Prompting is learned by doing, on your own emails, notes and questions. The SkillsVerx AI Skills course starts with exactly this and builds up to research, documents and custom assistants, with feedback on your prompts along the way.

Frequently asked questions

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

Mostly, yes. The four parts work in all of them. Each assistant has its own style, so the same prompt can give slightly different answers.

How long should a prompt be?

As long as it needs to be to include the role, task, context and format. For most daily tasks that is two to five sentences.

Can I write prompts in Urdu or Roman Urdu?

Yes. One approach worth testing is to write the instructions in simple English and ask for the reply in Urdu or Roman Urdu, then compare it with a prompt written fully in Urdu. Always read the reply before you use it.

Why does the same prompt give different answers?

AI assistants generate each reply fresh, so wording changes from one try to the next, and a model update can change it more. If you need consistent results, add an example of the answer you want and fix the format, such as a table or a word limit.

Is prompt engineering a real skill?

Writing clear prompts and checking the results is a practical skill that saves time at work and in study. It is part of using AI well, not a separate job for most people.
