Product Copy with AI: Sell Faster Without Risking a Cease-and-Desist Letter
The online shop has four hundred products. Every one needs a description that sells and doesn't sound copied straight from the manufacturer. Fifteen minutes per product is a hundred hours. Nobody manages that alongside running the store.
So you use the manufacturer's text. It appears word for word on six competitors' sites, Google penalizes duplicate content, and it doesn't sell either. A familiar dilemma.
What AI can do for product copy
You give it the facts: product, material, size, special feature, target audience. It turns them into three to four sentences that describe a benefit instead of a spec.
The difference is decisive. "100 percent merino wool" is a spec. "Merino wool regulates temperature and doesn't itch, unlike coarse wool" is a reason to buy.
Input: "Wool sweater, 100 percent merino, five colors, target audience: people who value high-quality natural materials." Result: a paragraph that describes the softness instead of just claiming it.
Where it gets legally tight
AI likes to write enthusiastically. That's allowed in advertising, as long as it stays opinion. As soon as it becomes a verifiable claim, Germany's Act Against Unfair Competition (UWG) applies.
Superlatives and comparisons
"Best price in town," "unbeatable quality," "cheaper than anywhere else." Statements like these become factual claims as soon as they're checkable. If you can't back them up, they can get you a cease-and-desist letter.
Cut every superlative from an AI-generated text that you couldn't back up with a source. The AI uses them because they're common in marketing copy, not because they're accurate.
Claims about effects and health
"Boosts concentration" on a toy, "good for your back" on a chair, "soothes the skin" on a cream. Depending on the product, Germany's Therapeutic Products Advertising Act, the Cosmetics Regulation, or the UWG again can apply here.
The rule of thumb: describe what the product is and does. Not what effect it has on a person.
Price information
Germany's Price Indication Ordinance requires prices to be complete and unambiguous. For discounted items, the previous price must be stated, specifically the lowest price of the last thirty days.
An AI knows nothing about your pricing over the last thirty days. Prices don't belong in the generated text, they belong in your shop system.
Have the AI write only the descriptive part. You maintain price, availability, shipping costs, and discount labeling in the shop itself. That way nothing in the text can be wrong.
The workflow for four hundred products
The trick is not to start from scratch four hundred times.
- Create a template for each product category: desired tone, length, target audience, forbidden phrases.
- Give the AI the template once, then just the facts for each next product.
- Ask for two versions, pick the better one.
- Cut superlatives and effect claims.
- Copy the text into the shop system, and maintain price and availability there.
By the tenth description, each one takes three minutes. Four hundred products then come to twenty hours instead of a hundred.
The underrated side effect
Original product copy is worth more to Google than copied manufacturer text. Anyone using the same description as six competitors is competing for the same search terms with identical content. Whoever has original copy gets found.
That's not a short-term effect. It's the reason the twenty hours are worth it.
What remains
In retail, AI isn't a salesperson. It's a very fast copywriter who doesn't know competition law and can't see your prices.
Use it for the description. Keep prices, superlatives, and effect claims under your own control. Then you save eighty hours and don't get a cease-and-desist letter.
