How to Write a Perfect Prompt for AI: A Step-by-Step Guide
In today’s world of AI-powered tools like ChatGPT, Gemini, and Copilot, the way you ask a question — or write a prompt — makes all the difference. Whether you’re a teacher designing classroom content or a marketer seeking campaign ideas, knowing how to write a good prompt can dramatically improve the quality of your AI-generated output.
This blog will walk you through the 5 essential building blocks of an effective prompt, based on Google’s framework, and provide real-world examples to help you apply each step confidently.
🧩 The 5 Parts of a Prompt
You can remember the components of a good prompt using the acronym PARTS:
- Persona
- Aim
- Recipients
- Theme
- Structure
Let’s break these down with practical tips and examples.
1. Persona: Identify Your Role
The first step in crafting a strong prompt is to set your identity. This helps the AI understand your point of view and what kind of response would be most relevant.
✅ Examples:
- I am a Math Department Lead analyzing resource gaps.
- I am a fashion startup founder looking for social media strategies.
- I am a life coach creating an emotional well-being toolkit.
By defining your persona, you narrow the context for better accuracy.
2. Aim: State Your Objective Clearly
Start your request with a verb and clarify what you want the AI to do. The goal should be specific and actionable.
✅ Examples:
- Brainstorm ideas for a product launch targeting Gen Z.
- Create an email sequence for abandoned carts in an eCommerce store.
- Design a lesson plan for teaching algebra to 10th graders.
This helps the AI zero in on the task without confusion.
3. Recipients: Define Your Audience
Tell the AI who the output is for, so it can adjust the tone, complexity, and content accordingly.
✅ Examples:
- For high school students new to Shakespeare.
- For marketing professionals with 5+ years of experience.
- For parents attending a school orientation session.
Audience definition ensures that the output feels tailored, not generic.
4. Theme: Choose a Tone or Style
You can customize the voice, tone, or even creative constraints of the AI’s response to match your brand or situation.
✅ Examples:
- Use a humorous and light-hearted tone with pop culture references.
- Maintain a formal and professional voice suitable for a board meeting.
- Be enthusiastic and include emojis for younger audiences.
This is where creativity comes in and transforms a bland reply into something engaging.
5. Structure: Specify the Format
How do you want the answer delivered? Bullet points, outline, infographic idea, email draft, code snippet? Mention it.
✅ Examples:
- Format as bullet points.
- Use a table to compare three options.
- Present as a storytelling script for YouTube Shorts.
Clear format instructions make it easy to use the result as-is.
Prompt Template You Can Use
Here’s a powerful plug-and-play template based on the framework:
I am a [persona]. [State your aim and recipients]. [Describe the theme and structure].
✅ Example:
I am a high school chemistry teacher. Create a quiz on the periodic table for 11th-grade students. Keep it fun and include a meme-style joke for each question. Format as a multiple-choice quiz.
