Prompt

A written instruction given to an artificial intelligence to tell it what is expected. It can be a command, a question, or a guideline expressed in natural language.

You can think of a prompt as a recipe or a creative brief:

  • It specifies what you want to get (e.g., a product description, a summary, an image…),
  • You can indicate a style, tone, length, or target audience,
  • It often includes contextual or reference information.

🎯 Prompt goal: to guide the AI so that it produces a coherent, useful, and tailored response.

The clearer, more structured, and more contextualized a prompt is, the more relevant the generated response will be.

🧭 What is a prompt used for?

A prompt can be used to:

  • Generate text (e.g., a summary, product sheet, LinkedIn post, email…),
  • Extract information (e.g., identify key points from a document),
  • Rewrite or improve content (e.g., correct style or adapt to an audience),
  • Create code, images, ideas

💡 Best practices for writing an effective prompt

A well-crafted prompt should generally answer the following questions:

  1. Who is speaking? → the role the AI should play.
  2. What is the task? → the main expected action.
  3. What is the subject? → the data or information to process.
  4. For whom? → the target audience.
  5. How? → tone, style, format, constraints.
