AI Copywriting vs a Human Copywriter: What Actually Sells

AI can write a sales page in seconds. So why does most AI copy fail to sell? Where AI copywriting helps, where it hurts, and how we combine AI speed with human research and judgement.

Ask an AI tool to write a sales page for your product and you'll have one in seconds. It will be grammatically perfect, well structured and full of confident claims. And it will probably sound exactly like every other sales page written by AI this year.

That's the problem with AI copywriting. It's not bad. It's average. And average copy doesn't sell.

Why AI copy sounds the same

AI tools write by predicting the most likely next words, based on the enormous amount of text they've learnt from. The most likely words are, by definition, the most common ones. So AI copy drifts towards the typical: "Unlock your potential." "Elevate your experience." "Seamless, innovative solutions."

Buyers have now read thousands of these sentences. They skim right past them.

What AI can't know

The bigger issue isn't style. It's knowledge. A tool can't know, unless you tell it:

  • What your buyers are actually afraid of.
  • The exact words they use in your WhatsApp chats.
  • Why your last three customers chose you over a competitor.
  • What your competitors are saying, and the gap they've left.
  • Which of your claims you can prove.

The best copy comes from that knowledge. A human copywriter's real job is research and judgement. Typing is the easy part.

Where AI genuinely helps

We use AI every day. It's useful for:

  • Summarising research: reading hundreds of reviews and pulling out themes.
  • First drafts: getting a structure on the page quickly.
  • Variations: turning one strong hook into twenty versions to test.
  • Volume: product descriptions for a large catalogue, then edited by a person. See how to write product descriptions.
  • Editing: spotting long sentences and unclear phrases.
  • Translation drafts: a starting point that a fluent speaker checks.

Where AI hurts

  • Making claims you can't back up. AI will happily invent statistics and results. Every claim needs checking.
  • Generic positioning. It will describe you the way it would describe anyone in your category.
  • Wrong cultural tone. It often defaults to American phrases and references that sound off to Ghanaian buyers.
  • Missing the real objection. It doesn't know your buyers worry about fakes, delivery or MoMo scams unless you tell it.

How to use AI for copy if you do it yourself

  1. Feed it your research. Paste in real reviews, real customer questions and your competitors' claims.
  2. Give it a clear structure. Ask for a PAS advert or a specific page structure. See ad copywriting formulas.
  3. Ask for many versions, then pick the best lines.
  4. Rewrite in your own voice. See brand voice.
  5. Check every fact.
  6. Cut the AI phrases: "unlock", "elevate", "seamless", "in today's fast-paced world".

The test that matters

Don't judge copy by how it reads. Judge it by what it does. Run the AI version and the human version in adverts and see which brings more sales. In our experience, copy built on real research wins.

Common questions

Will Google penalise AI-written content?

Google's stated position is that it rewards helpful content, however it's produced. Generic, unhelpful content does poorly whether a person or a tool wrote it. See AI content and SEO.

Can AI write in Ghanaian English?

It can approximate it if you give it examples. A local writer still catches what sounds wrong.

Do you use AI for client copy?

Yes, for research and drafts. The message and the final words come from our research and our writers. See our copywriting service.
