What's a good AI prompt for writing product descriptions that convert without sounding fake

The Prompt

Write a product description for [product name].

Real specs/features: [materials, dimensions, what it actually does]
Who buys this and why: [primary use case/customer]
Tone: [brand voice — casual, premium, technical, etc.]

Lead with the problem it solves or the specific way it's used, not a list of adjectives. Avoid generic claims like "premium quality" or "you'll love it" — state real, specific facts instead.

Why This Prompt Works

Generic superlative-heavy copy (“premium quality,” “you’ll love it”) has become invisible to shoppers who’ve seen it on nearly every listing — descriptions that lead with a concrete use case or problem solved convert better because they let the shopper self-identify as the target customer.

How to Customize It

Supply the real spec sheet and actual use cases rather than letting the model invent features — accuracy matters both for conversion and for return-rate/liability reasons. If the product has a common failure mode or limitation, consider naming it directly; a brief, honest caveat often builds more trust than copy that reads as unconditionally positive.

Common Mistakes to Avoid

Don’t let unverified claims slip in (health claims, “best,” “guaranteed”) — beyond hurting trust, some of these carry real regulatory exposure depending on the product category. Also avoid writing the same structural template for every product in a catalog; descriptions that all read like the same fill-in-the-blank form stop converting once a shopper notices the pattern.

Bottom Line

Product copy that names a real use case and concrete specs, instead of stacking generic superlatives, is what actually moves shoppers who’ve become blind to typical listing language.
