How to Write Better AI Prompts: 7 Techniques That Actually Work

If you have ever asked ChatGPT or Claude a question and received a vague, generic answer, the problem is usually not the AI. It is the prompt. The way you ask determines the quality of what you get back. After using AI tools daily for everything from writing emails to building Excel macros, here are the seven techniques that consistently produce better results.

1. Give Context Before the Question

Instead of asking “How do I write a formal email?”, tell the AI who you are and what the situation is: “I am an accountant writing to a customer who has not paid an invoice that is 60 days overdue. Write a polite but firm reminder email.” The more the AI knows about your situation, the more relevant the answer.

2. Specify the Format You Want

AI models will happily guess at formats, but guessing wastes your time. Say exactly what you want: “Give me a table with three columns”, “Write this as bullet points”, “Keep it under 100 words”, or “Respond only with the code, no explanation”. You will save several back-and-forth messages.

3. Show an Example

This is the single most underrated technique. If you want the AI to match a certain style, paste an example of that style. “Here is an email I wrote before. Match this tone for a new email about X.” AI models are excellent at imitating patterns you show them.

4. Ask It to Think Step by Step

For anything involving logic, calculations, or multi-part problems, add “think through this step by step before answering”. This simple phrase dramatically reduces careless mistakes, especially in math and reasoning tasks.

5. Assign a Role

Starting a prompt with “Act as an experienced VBA developer” or “You are a career coach” focuses the AI’s answers. Roles work because they narrow down the enormous range of possible responses to the ones an expert in that field would give.

6. Iterate Instead of Restarting

Your first prompt does not need to be perfect. If the answer is close but not quite right, say what to change: “Make it shorter”, “Less formal”, “Add a section about pricing”. Treat it like a conversation with a colleague, not a search engine.

7. Tell It What Not to Do

Negative instructions are powerful: “Do not use jargon”, “Do not start with an introduction”, “Avoid bullet points”. If the AI keeps doing something annoying, explicitly rule it out.

Final Thoughts

Good prompting is not about magic words. It is about communicating clearly, the same way you would brief a smart new colleague. Give context, show examples, specify the output, and refine as you go. Master these seven habits and every AI tool you touch becomes noticeably more useful.
