1. What is an AI prompt?
An AI prompt (or “instruction”) is the text you enter into an artificial intelligence interface to obtain a response. It is the command, question, or instruction you give to a language model like ChatGPT, Claude, Gemini, or Mistral. In simple terms: if the AI is an engine, the prompt is the accelerator. The quality of your prompt directly determines the quality of the response you will obtain.
The different types of prompts
| Prompt Type | Description & Example |
| Direct Instruction | “Write a B2B prospecting email for a SaaS startup” |
| Open Question | “What are the benefits of AI automation for SMEs?” |
| Role Prompt | “You are an SEO expert. Analyze this page and suggest improvements.” |
| Iterative Prompt | “Take the text above and rewrite it in a journalistic style” |
| Chained Prompt | “First, summarize this document, then list the 5 key points, then propose 3 catchy titles” |
| Few-Shot Prompt | “Here are 3 examples of successful taglines: […]. Create 5 new ones for my product.” |
💡 PROMPT ENGINEERING: The term “prompt engineering” refers to the discipline of designing optimal prompts to obtain the best responses from an AI model. It is a highly sought-after skill in the corporate world today.
2. Why are prompts so important?
Most users get mediocre results from AI not because the tool is bad, but because their prompt is vague, incomplete, or poorly structured. A bad prompt produces a generic response; a good prompt produces a precise, useful, and actionable one.
The 3 reasons your prompts fail:
- Too vague: “Talk to me about marketing” → The AI doesn’t know where to start.
- No context: No details about your sector, audience, or objective.
- No expected format: You get a wall of text when you wanted a list.
The relationship between effort and quality: Studies and feedback from thousands of users show that an extra 20 seconds spent on a prompt can multiply the quality of the response by 5. The effort invested in writing a good prompt is always profitable.
3. FAQ: Frequently Asked Questions about prompts
- How do you make a good prompt? A good prompt contains: a role (“you are an expert in…”), precise context, a clear task, an expected output format, and constraints.
- How do you make an effective ChatGPT prompt? Specify: 1) your final goal, 2) the target audience, 3) the desired tone, 4) the expected length, and 5) an example if possible.
- What is the difference between a prompt and a command? A command is a precise, unique instruction (“Translate this text into English”). A prompt can be more nuanced: it includes context, examples, and constraints.
- Can you sell prompts? Yes! Marketplaces like PromptBase, Etsy, or Gumroad allow creators to sell their best prompts.
- What is “prompt engineering”? It is the art and science of drafting optimized prompts. Some professional prompt engineers earn up to $300,000/year in the U.S..
4. How to write a good prompt: the RACED method
The RACED method is a simple framework to structure your prompts effectively:
| Letter | Meaning & Explanation |
| R — Role | Give the AI a role. Ex: “You are a copywriter expert in B2B SaaS” |
| A — Action | Describe the task precisely. Ex: “Write an onboarding email sequence” |
| C — Context | Provide context. Ex: “For a startup selling a project management tool” |
| E — Examples | Give examples. Ex: “Here are 2 emails I like: […]” |
| D — Details | Specify format, length, tone, constraints. Ex: “3 emails, conversational tone, max 150 words each” |
Applying the RACED Method — A Concrete Example
| 📝 CONCRETE EXAMPLE — RACED METHOD ROLE: You are a content marketing expert specializing in SEO. ACTION: Write an introduction for a blog article. CONTEXT: The article is about AI prompts for beginners. The blog is aiseful.com and targets English-speaking entrepreneurs who are just discovering AI. EXAMPLES: The introduction should hook readers with a surprising statistic or a provocative question. DETAILS: Maximum 120 words, accessible and engaging tone, include the keyword “AI prompt” in the first 2 lines. |

- Not iterating: The first prompt is rarely optimal. Refine, rephrase, add constraints.
- Going too long upfront: Start simple, then add complexity as needed.
- No length constraints: Without guidance, the AI may be too brief or too verbose.
- Ignoring tone: “Professional”, “friendly”, “academic”, “conversational” radically change the response.
- Not mentioning the audience: The AI doesn’t know who you’re writing for unless you say so.

- Forgetting business context: Your industry, competitors, and specific constraints must be mentioned.
