How to write AI prompts that actually work

Writing AI prompts that actually work means giving the tool three things every time: the real context, the exact output you want, and an example of good, so it stops guessing at what "good" means.

Why do my ChatGPT prompts give generic answers?

Because you are asking a stranger to write for your business without telling them anything about it. Type "write a follow-up email to a customer" and you get the follow-up email everyone gets, because that is the only information the tool has to work with. It is not being lazy. It genuinely does not know your prices, your tone, or what this particular customer already said.

The fix is not a cleverer sentence. It is more of the right information, handed over plainly.

AI prompts for small business: the four things to include

Most reliable prompts, across every tool I have used with clients, have the same four parts. Leave one out and you can usually tell which one from the answer you get back.

  • Who it is for. Not "a customer", but the actual situation: a landscaping client who has asked twice why their quote is late.
  • What you already know. Paste in the real email, the real quote, the real numbers. Do not summarise it in your head first and hand over your summary. Hand over the thing itself.
  • What you want out the other end. A draft email, three subject line options, a shortened version of a report, a list sorted by urgency. Say the format, not just the topic.
  • What good looks like. One real example, in your own words if you have one, or a rule like "keep it under 80 words and don't apologise more than once."

A prompt built from those four is longer than "write me an email", and that is the point. Length is not the enemy here. Vagueness is.

ChatGPT prompts for business owners: a template you can reuse

Here is the shape I hand to clients, filled in for a real situation: a café owner replying to a one-star review about slow service on a Saturday.

"You're replying to a Google review for my café on behalf of the owner. The review says: [paste review]. We were short-staffed that weekend and have since hired someone. Write a short, warm reply that acknowledges the wait without over-apologising, mentions the new hire briefly, and invites them back. Keep it under 60 words. Here's a reply I wrote to a similar review last month that I liked: [paste old reply]."

Swap the details and that same shape covers a supplier chasing email, a job description, or a social post about a new opening hour. The parts do not change: the situation, the raw material, the format, and one example of the standard you are holding it to.

How do I get AI to sound like me and not like a robot?

Give it your own writing, not instructions about your writing. "Write in a friendly, professional tone" produces the same beige voice for every business that types it, because "friendly, professional" describes almost nobody in particular. Paste three or four short pieces you have actually written (an email, a review reply, a text to a supplier) and ask it to match that voice instead. It is far better at copying a real example than following an adjective.

Keep a short file of your best three examples: one email, one social caption, one reply to a complaint. Paste from that file every time you ask for something in your voice, and the results stop drifting.

Prompt writing tips for getting a first draft you can actually use

A few habits that save the most editing time afterwards:

  1. Ask for options, not one answer. "Give me three versions, one short and direct, one warmer" gets you a choice instead of one draft you have to fight with.
  2. Tell it what to leave out. "Don't mention the delay, we're not drawing attention to it" stops it inventing an apology you did not want.
  3. Correct it in plain language, in the same conversation. "That's too formal, try again like you're texting a friend" works better than starting over with a longer prompt.
  4. Reuse what works. When a prompt gives you a genuinely good result, save it. Next month's version of the same task starts from something proven instead of a blank box.

None of this is really about prompts, if you look at it straight on. It is about giving the tool the same information you would give a new employee on their first day: here is who we're dealing with, here is what we know, here is what good looks like around here. Type that out once and reuse it, and the "AI wrote this" problem mostly disappears, because it stops sounding like AI and starts sounding like whichever example you handed it.

Where this tends to break down is not the wording, it's the discipline of actually building that file of good examples and reusing it. Most owners write a great prompt once, get a great result, and never save it anywhere. If you want help setting up that system properly, rather than reinventing a prompt every time, that is one of the smaller things I look at inside the AI Assessment, alongside the bigger automation opportunities in the week. It sits close to what I wrote about taming an inbox with AI, since email is where most owners write the same prompt over and over without noticing.

If you are still deciding whether any of this is worth the time, the best AI tools for Irish small businesses is a reasonable place to start before you get into prompting them well.
