How to Write Better Prompts (a Plain-English Guide)

Editor’s Note: New post, October 2026.

Research review: prompting guidance checked October 17, 2026 against published 2026 prompt guides and official-style prompting advice. No hands-on testing was needed for this piece.

Key Takeaways

  1. Name the job, the reader, and the shape of the answer. Those three lines fix most weak prompts.
  2. Show one short example of what good looks like, instead of adding more adjectives.
  3. Fix one thing at a time in your follow-up, and say what to keep.

In a sentence: Better prompts are not clever tricks, they are clear instructions: say what you want, who it is for, and what the finished answer should look like.

Plain-English Verdict

You do not need a course, a cheat sheet of magic phrases, or a new vocabulary. Write the prompt the way you would brief a helpful colleague who knows nothing about your situation: the task, the background that matters, and the shape of a good answer. Then read the reply, name one thing to fix, and go again. Two rounds of that beat one enormous perfect prompt almost every time.

Let’s do this together. A prompt is just the instruction you type to an AI assistant such as ChatGPT or Claude. (We compared those assistants in ChatGPT vs Claude vs Gemini for everyday questions.) Think of it like giving directions to a driver who is excellent at driving and terrible at guessing where you live. More detail about the destination beats shouting “drive better.”

Step 1: Name the job in one verb

Start with what should happen: write, summarise, compare, explain, rewrite, or plan. “Write about marketing” is a topic, not a job. “Write a 150-word product description” is a job, and the assistant can start immediately.

Quick check: if a person reading only your first line could not say what to produce, the prompt needs a verb and an object.

Step 2: Add the background

Add one or two sentences of context: who you are, who will read this, and any limit that matters. A bakery owner, a student, and a lawyer need different answers to the same question, and the assistant cannot know which one you are. Keep it relevant. Your life story does not help, but your audience, deadline, and budget often do.

Step 3: Say what good looks like

Name the shape: a table, five bullet points, three short paragraphs, or under 200 words. Name the tone in plain words: friendly, formal, or no jargon. If length and shape matter, say so here, not after you have read 900 words you did not want. This is also where our explainer on what an AI agent is helps: the clearer the finished shape, the more safely any tool can work on its own.

Step 4: Show one example

One short example is worth a paragraph of adjectives. Paste a description, email, or paragraph you like and say “match this style.” The assistant copies patterns far better than it interprets words like “punchy.” Be careful, though: it will copy the example’s flaws too, so pick an example you would happily sign.

Step 5: Fix one thing at a time

Here’s the part everyone misses. The first answer is a draft, not a verdict. Reply with one change and one thing to keep: “Keep the first two paragraphs exactly as they are. Make the ending shorter and add one example.” Asking for shorter, funnier, and more formal in the same breath pulls in three directions and produces mush. One clear fix per round is faster, even though it feels slower.

A weak prompt, rebuilt

Weak: “Write an email.” Better: “Write a short, polite email to a client named Ana. I need to move our call from Tuesday to Thursday morning because of a school event. Offer two times, keep it under 120 words, and end by apologising once, briefly.” Nothing in that prompt is clever. Every line removes a guess.

Prompt Station: Paste this into ChatGPT or Claude: “Improve this prompt so it produces a more specific and useful answer. Show the improved prompt first, then list what you changed in three bullet points. My prompt is: [paste yours here].” Open in ChatGPT · Open in Claude
