The difference between a vague AI answer and a genuinely useful one is usually the request, or prompt, you gave it. You do not need special tricks or secret phrases. You need to tell the AI what a good human assistant would need to know. This guide shows a simple formula that works with any chatbot.
Why prompts matter
An AI chatbot only knows what is in your message and the conversation so far. If you ask “Write an email to my landlord”, it has to guess the problem, the tone, the length and what you want to happen. Guesses lead to generic answers, more back-and-forth, and on free plans, more of your limited messages or credits used up. A clear first prompt saves time and usage.
The five-part formula
- The task: what you want, in one sentence. “Write a short email.”
- The context: the background the AI cannot know. “My kitchen tap has been leaking for two weeks and I reported it on the 3rd.”
- The goal: what a good result achieves. “I want it fixed this week without sounding rude.”
- The format: length, structure, style. “Under 120 words, polite but firm, with a clear request.”
- The material: anything to base the answer on. Paste the earlier email, the document or the data.
Put together: “Write a short email to my landlord. My kitchen tap has been leaking for two weeks; I reported it on the 3rd and heard nothing. I want it fixed this week without sounding rude. Under 120 words, polite but firm, ending with a clear request for a repair date.”
Before and after
Weak: “Explain inflation.”
Better: “Explain inflation to a 15-year-old in under 200 words, with one everyday example about grocery prices.”
Weak: “Make my CV better.”
Better: “Here is my CV and a job ad for a junior data analyst. Suggest five specific changes to make my CV match the ad. Do not invent experience I do not have.”
Weak: “Give me dinner ideas.”
Better: “Give me five vegetarian dinners for two that take under 30 minutes, using mostly pantry ingredients. List ingredients for each.”
Five habits that make a big difference
- Say who it is for. “For a beginner”, “for my manager”, “for a 10-year-old” changes the whole answer.
- Ask it to ask you. “Before you start, ask me any questions you need.” Great for bigger tasks.
- Give an example of the style you like, and say “match this tone”.
- Set limits: word counts, bullet points, “no jargon”.
- Allow uncertainty: “If you are not sure, say so.” This reduces made-up details, a problem we explain in why chatbots make things up.
Common beginner mistakes
- Too short. One-line prompts get one-size-fits-all answers.
- Too many tasks at once. Split “research, outline, write and translate” into steps.
- Never giving feedback. Instead of starting over, say what to change: “Shorter, and remove the second paragraph.”
- Endless chats. Very long conversations get slower, cost more of your allowance, and drift. Start fresh for new topics.
- Sharing private data carelessly. Read what not to share with AI chatbots first.
A prompt you can copy
I need help with [task]. Background: [what the AI needs to know]. The result should [goal]. Format: [length, structure, tone]. Here is the material to use: [paste]. Ask me questions first if anything is unclear.
Use this template for a week and you will notice two things: answers you can use straight away, and free limits that last much longer. For more on those limits, see AI credits and tokens explained.
