QUICK ANSWER
Better prompts give the AI the context a smart colleague would need: who it’s for, what you want, what good looks like and what format to use. Be specific, show an example when you can, break big jobs into steps, and ask it to check its work. Then refine the answer instead of starting over.
AI assistants like ChatGPT, Claude and Gemini all follow the same basic rule: the clearer your request, the better the result. You don’t need special tricks. These techniques come straight from the providers’ own prompting guides.
The 6 habits of good prompts
- Give context. Say who the output is for and why. “Explain inflation” is vague; “Explain inflation to a 15-year-old in three short paragraphs” is clear.
- Be specific about the task. Name the length, tone, audience and what to include or leave out.
- Show an example. Paste a sample of the style or format you want. Examples steer the AI more than descriptions do.
- Ask for a format. A table, bullet list, email or step-by-step plan, so the answer is easy to use.
- Break big jobs into steps. Ask for an outline first, then each section, instead of everything at once.
- Ask it to check its work. For example: “List any assumptions you made” or “Point out anything you’re not sure about.”
Weak vs strong prompts
| Weak prompt | Stronger prompt |
|---|---|
| Write a blog post about EVs. | Write a 600-word blog post for first-time car buyers comparing EVs and petrol cars on running costs. Use plain English, three H2 headings and end with a short checklist. |
| Summarise this. | Summarise this report in 5 bullet points for a busy manager. Put the main recommendation first. |
| Make it better. | Make this email shorter and more polite. Keep the deadline and the three action items. |
Common mistakes
- Asking several unrelated things in one prompt.
- Leaving out key facts the AI can’t know, such as your audience, budget or deadline.
- Accepting the first answer. Follow-up instructions like “shorter”, “more examples” or “simpler words” usually improve it fast.
- Trusting facts without checking. AI can state wrong information confidently, so verify anything important against a reliable source.

Frequently asked questions
Do prompts work the same in every AI tool?
The basics work everywhere: clear context, examples and a defined format. Each model has small differences, so test and adjust.
Is “prompt engineering” a real skill?
Yes. Writing clear instructions for AI is increasingly useful in many jobs, from marketing to coding. It’s mostly clear thinking and clear writing.
How long should a prompt be?
As long as it needs to be. A detailed prompt with context and an example often beats a short one.
