Most product descriptions say the same thing: what the item is, maybe a size or material, and nothing else. That’s not wrong, it’s just not doing any work — it describes the product instead of selling it. Here’s how to fix that in a few minutes, using free AI, with a real before-and-after.
The before
A typical small-business product description looks like this:
“Handmade ceramic mug. Holds 350ml. Dishwasher safe.”
Accurate, and completely forgettable. It answers “what is this” and stops there — it never answers “why would I want it.”
The prompt that fixes it
Give ChatGPT or Gemini the basic facts plus one thing most people skip — who’s actually buying it and why:
“Write a product description for a handmade ceramic mug, 350ml, dishwasher safe. It’s bought mostly as a gift or for someone’s morning coffee routine. Make it two short sentences, warm and specific, not generic marketing language. Focus on how it feels to use, not just what it is.”
The after
A prompt like that typically produces something closer to:
“A mug that makes the first coffee of the day feel a little more deliberate — handmade, holds a full 350ml, and goes straight in the dishwasher after. The kind of thing that’s easy to buy for someone else because it’s genuinely nice to use yourself.”
Same facts. The difference is entirely in what the description is actually for — one states specifications, the other gives someone a reason to picture using it.
The part people get wrong: too much AI polish
The most common mistake isn’t under-using AI, it’s over-trusting the first draft. AI writing tends to drift toward generic marketing phrases — “elevate your experience,” “crafted to perfection” — the exact tone that makes a description forgettable again. If a line could describe literally any product in that category, cut it or ask for a rewrite that’s more specific to this one.
A quick way to check: read the description without seeing the product photo. If you can’t tell what’s actually distinctive about this specific item, it needs another pass.
Doing this for a whole catalog
For more than a handful of products, keep the same prompt structure and just swap the specifics — product, buyer, occasion — rather than writing a new prompt from scratch each time. Save the working version once you land on a phrasing and tone you’re happy with, and reuse it as a template.
This is the same underlying idea behind turning one product photo into multiple social posts — a reusable brief beats reinventing the approach every time. If you want a full system built around that idea — a brief you fill in once that generates prompts for descriptions, social posts, and captions together — that’s what Market Your Business With AI covers in more depth.
Frequently asked questions
ChatGPT and Google Gemini both handle this well on their free tiers. The tool matters less than the prompt — being specific about the buyer and the feeling the product gives, not just its specifications, is what actually improves the result.
Watch for phrases that could describe almost any product in the category — “elevate your experience,” “crafted to perfection” — and either cut them or ask for a rewrite that’s more specific to this exact item. If a description makes sense without seeing the product photo, it’s too generic.
Shorter than most people default to. Two or three specific sentences that give a real reason to want the product usually outperform a long paragraph of generic detail.
Yes, with the specifics swapped each time — the product, who buys it, and why. Reusing one well-tested prompt structure is faster and more consistent than writing a new one for every item.
