When I first used AI to write product descriptions, they all came out of the same factory: "Elevate your lifestyle with this premium, high-quality, versatile essential." Every product sounded like every other product. Conversion didn't move, because nobody believes "premium versatile essential" about anything.
The problem wasn't the AI. It was the brief.
What was wrong
- No brand voice. Generic praise reads as generic, and shoppers skim past it.
- Adjective stacking. "Premium, high-quality, durable" is three words for one empty idea.
- Zero specifics. A description without a use case or a measurement is just noise.
The fix I use now
- Give it one brand sentence. "We sound like a knowledgeable friend, not a catalog." That single line changes every output.
- Ban the filler words. Same list as always: premium, robust, seamless, elevate, versatile. If one appears, the sentence is doing no work.
- Force one concrete detail. A dimension, a use case, a "great for small kitchens" line. Specifics are what make a description feel written by someone who touched the product.
Before I publish a batch, I paste the descriptions into a free AI-risk scorer: https://humanizeai-lab.pages.dev/tools/ai-risk-scorer.html — if they score over 40%, they'll read as AI to customers too. The fixed prompt set I use for product, landing, and ad copy is here: https://felovery.gumroad.com (code FIRST50 = 50% off, no expiry).
The descriptions that converted best weren't the ones AI wrote fastest. They were the ones that sounded like a person who'd actually used the thing. What's the product you've struggled to describe?
