A prompt is the instruction or question you give to ChatGPT. The quality of your prompt directly affects the quality of the response.
In this tutorial, you will learn how to write your first prompt correctly and how to improve it for better results.
What is a Prompt?
A prompt is simply the text you type into ChatGPT.
Examples of prompts:
- Explain artificial intelligence in simple words.
- Write a professional email for leave application.
- Create a login form using PHP and MySQL.
- Suggest business ideas for a startup.
The clearer your prompt, the better the output.
Step 1: Start with a Clear Instruction
When writing your first prompt:
- Be specific
- Avoid vague questions
- Mention exactly what you want
❌ Weak Prompt:
Write about marketing.
✅ Better Prompt:
Explain digital marketing strategies for small businesses in simple language.
The second prompt gives clearer direction.
Step 2: Add Context
Context helps ChatGPT understand your situation.
Example:
❌ Basic Prompt:
Write a resume.
✅ Improved Prompt:
Write a resume for a PHP developer with 2 years of experience in Laravel and MySQL.
Adding context produces more accurate results.
Step 3: Define the Output Format
You can control how ChatGPT responds.
For example:
- Explain in bullet points.
- Write in 200 words.
- Use simple language.
- Provide step-by-step explanation.
Example Prompt:
Explain database normalization in simple words using bullet points.
This ensures structured output.
Step 4: Assign a Role (Optional but Powerful)
You can ask ChatGPT to act as someone.
Examples:
- Act as a professional web developer.
- Act as an SEO expert.
- Act as a business consultant.
- Act as a teacher.
Example:
Act as a PHP developer and create a secure login system with validation.
Role-based prompts improve quality.
Step 5: Ask Follow-Up Questions
ChatGPT works best in conversation.
If the response is not perfect, you can say:
- Make it shorter.
- Add example.
- Explain in more detail.
- Improve the code.
You can refine responses step-by-step.
Example: Writing Your First Prompt
Let’s try a practical example.
Prompt:
Explain what machine learning is in simple words for beginners.
ChatGPT Response:
Machine learning is a type of artificial intelligence that allows computers to learn from data and improve over time without being explicitly programmed.
This is a clear and helpful answer because the prompt was clear.
Common Beginner Mistakes
Many new users make these mistakes:
- Writing very short or unclear prompts
- Not specifying the required format
- Expecting perfect results in one try
- Not providing enough details
Better prompts give better answers.
Simple Formula for Writing a Good Prompt
You can follow this structure:
Role + Task + Context + Format
Example:
Act as a Laravel developer. Create a secure login system for a small business website. Provide code with explanation in simple language.
This formula works very well.
Practice Exercise
Try writing your own prompt like this:
Explain object-oriented programming for beginners using real-life examples.
Then refine it:
Explain object-oriented programming for beginners using real-life examples in 300 words with bullet points.
See the difference in results.
Summary
A prompt is the instruction you give to ChatGPT. Clear, detailed, and structured prompts produce better responses.
To write a good prompt:
- Be specific
- Add context
- Define output format
- Assign a role if needed
- Refine with follow-up questions
