ChatGPT: Prompts

If you’ve ever typed something into ChatGPT and thought, “That’s not exactly what I meant…” — you’ve already discovered why prompt writing matters.

A prompt is simply the instruction or message you give to an AI system like ChatGPT. The better your prompt, the better the result.

This tutorial will teach you:

  1. What a prompt really is
  2. The basic structure of a good prompt
  3. Step-by-step methods for beginners
  4. Practical examples
  5. Advanced tips when you’re ready

1. What Is a Prompt?

A prompt is any input you give to ChatGPT.

Examples:

  • “Explain photosynthesis.”
  • “Write a professional email declining a job offer.”
  • “Summarize this article in 5 bullet points.”

Think of ChatGPT as:

  • Extremely knowledgeable
  • Very fast
  • But not a mind reader

If you are vague, the output will be vague. If you are precise, the output becomes precise.

2. The Core Principle: Clarity + Context + Constraints

Great prompts usually include three elements:

1️⃣ Clarity (What do you want?)

Be explicit about the task.

Bad:

Tell me about history.

Better:

Explain the causes of World War I in simple terms.

2️⃣ Context (Why / For whom?)

Give background so ChatGPT understands your situation.

Instead of:

Write a speech about climate change.

Try:

Write a 3-minute speech about climate change for high school students. The tone should be persuasive but not aggressive.

3️⃣ Constraints (How should it look?)

Specify format, length, style, or structure.

Examples:

  • “In 5 bullet points”
  • “Under 200 words”
  • “Use simple vocabulary”
  • “Include examples”
  • “Make it formal”

3. The Basic Prompt Formula for Beginners

Use this simple structure:

Role + Task + Context + Format + Constraints

Let’s break it down.

Step 1: Assign a Role (Optional but Powerful)

You can guide tone and expertise by assigning a role.

Examples:

  • “You are a marketing expert…”
  • “You are a high school teacher…”
  • “You are a cybersecurity specialist…”

This helps shape the style and depth.

Step 2: Define the Task Clearly

Use strong action verbs:

  • Explain
  • Compare
  • Analyze
  • Summarize
  • Rewrite
  • Translate
  • Generate
  • Critique

Example:

Explain how blockchain works.

Better:

Explain how blockchain works in simple language for beginners.

Step 3: Add Context

Provide details about:

  • Audience
  • Purpose
  • Your level
  • Situation

Example:

I’m preparing for an IELTS speaking test. Help me generate a Band 7-level answer to the topic “Describe a memorable trip.”

Step 4: Specify the Output Format

Tell ChatGPT exactly how to structure the response.

Examples:

  • Bullet points
  • Table
  • Step-by-step guide
  • Email format
  • Code block
  • Dialogue
  • Checklist

Example:

Give me a comparison table between Python and JavaScript for beginners.

4. Examples: Bad Prompt vs Good Prompt

❌ Example 1

Bad:

Write about exercise.

Good:

Write a 300-word article about the benefits of daily exercise for office workers. Use simple language and include 3 practical tips.

❌ Example 2

Bad:

Help with my resume.

Good:

Rewrite this resume summary to sound more professional and achievement-oriented. Keep it under 120 words. Here is the text: [paste text]

❌ Example 3

Bad:

Explain AI.

Good:

Explain artificial intelligence to a 12-year-old using simple examples from daily life.

5. Use Examples Inside Your Prompt

If you want a specific style, show one.

Example:

Write 5 Instagram captions in this style: “Small steps today, big results tomorrow.”

This dramatically improves accuracy.

6. Iterative Prompting (Very Important)

You don’t need a perfect prompt the first time.

You can refine step by step:

  1. Ask broadly.
  2. Improve.
  3. Narrow it down.

Example flow:

You:

Give me business ideas.

Then:

Focus on low-cost online businesses.

Then:

Now only ideas suitable for a college student with programming skills.

This is how professionals use AI.

7. Common Beginner Mistakes

❌ Being Too Short

“Explain economics.”

Too broad → generic answer.

❌ Being Too Vague

“Make it better.”

Better:

Improve clarity and make it more persuasive.

❌ Forgetting the Audience

Different audiences require different language.

  • Kids
  • Experts
  • Customers
  • IELTS examiners
  • Investors

Always specify.

8. Advanced Techniques (When You’re Ready)

1️⃣ Ask for Structure First

Example:

Give me an outline first. After that, I will ask you to expand each section.

2️⃣ Ask for Multiple Options

Give me 3 different tones: formal, friendly, and persuasive.

3️⃣ Ask for Self-Critique

After writing the answer, evaluate it and suggest improvements.

4️⃣ Chain of Thought Guidance

Instead of:

Solve this math problem.

Try:

Solve this math problem step by step and explain your reasoning.

9. A Universal “Power Prompt” Template

Here is a template beginners can copy:

You are a [role].

Task:
[What you want done]

Context:
[Background information]

Requirements:
- Format:
- Length:
- Tone:
- Audience:
- Special instructions:

10. Final Advice

Think of ChatGPT as:

  • A very capable assistant
  • That follows instructions literally
  • And performs best with structured guidance

The quality of output = clarity of input.

If you improve your prompting skill, you improve:

  • Learning speed
  • Writing quality
  • Research efficiency
  • Coding productivity
  • Exam preparation
