A prompt is the instruction or question you give an AI tool to get a response. The quality and clarity of your prompt strongly affect the quality of the AI’s output — which is why ‘prompting’ has become a useful skill.

What is a prompt?

A prompt is simply what you type (or say) to an AI. It can be a question (‘Explain photosynthesis’), an instruction (‘Write a polite reply to this email’), or a longer brief with context and examples. The AI reads your prompt and generates a response based on it.

Why do prompts matter?

Because AI generates from your input, a vague prompt gives a vague answer, while a clear, specific prompt with context gives a much better one. Telling the AI the role, audience, format and constraints you want (‘Write a 100-word summary for beginners’) usually improves results dramatically.

How do I write a good prompt?

Be specific, give context, state the format you want, and include examples where helpful. You can also ask the AI to ask you questions first. Prompting is iterative — refine your prompt based on the output. See our guide on writing good prompts for examples.
