Writing better AI prompts: five habits that give you better answers
Most disappointing AI answers come from short, vague prompts. A few habits fix most of it.
- Say who the answer is for: "Explain this to a Class 10 student" gives a very different answer than "explain this".
- Give context: paste the email, the error message or the notes you are working from.
- Ask for a format: a table, five bullet points, under 100 words.
- Ask it to ask you questions first when the task is complex.
- Iterate: reply with what to change instead of starting over.
A before and after
Before: "Write a leave application." After: "Write a short, polite leave application to my manager for two days off next week for a family function. Keep it under 80 words." The second prompt gets a usable answer the first time.
Save the prompts that work. Keep a simple note on your phone with your best five prompts and reuse them. Small tweaks to a good prompt beat starting from zero each time.
A simple prompt formula
A reliable structure is: role, task, context, format, limits. For example: "You are a helpful school teacher. Explain photosynthesis to a Class 7 student. They struggle with long paragraphs. Use five short bullet points and one everyday example. Keep it under 120 words." Each part removes guesswork for the AI.
Prompts you can copy
- Summarise: "Summarise this document in 5 bullet points for a busy manager. Then list any deadlines or numbers mentioned."
- Rewrite: "Rewrite this email to sound polite but firm. Keep my main points. Under 100 words."
- Learn: "Teach me Excel VLOOKUP step by step with a tiny example table. Then give me one practice question."
- Decide: "I am choosing between these two laptops for college coding. Compare them in a table and tell me which you would pick and why."
- Brainstorm: "Give me 10 blog post ideas about saving money on electricity in Indian homes. One line each."
Fixing a bad answer
Instead of starting over, tell the AI exactly what was wrong: too long, too formal, missing a point, wrong audience. Follow-up instructions are usually faster than writing a brand new prompt. If an answer contains facts, ask it which parts it is unsure about.
Mistakes to avoid
- Asking several unrelated questions in one prompt
- Leaving out who the answer is for
- Accepting statistics, dates or quotes without checking them
- Pasting private or confidential information
Frequently asked questions
Do I need special prompt engineering courses? No. Clear instructions, context and an example of what you want cover most everyday needs.
Should I be polite to AI? It does not affect the AI's feelings, but clear, complete sentences often lead to clearer answers.
Write prompts the way you would brief a smart new colleague on their first day: what you need, who it is for and what good looks like.
