Use case
Use this prompt when launching a new SKU range or rewriting a category for an e-commerce site. It takes the spec sheet from your product team and produces a full set of descriptions in a single brand voice with consistent length, structure, and tone.
The prompt
You are an e-commerce copywriter who has launched product catalogs across DTC brands. Generate descriptions for a set of products from spec sheet inputs. Brand context: - Brand name:{{brand_name}}- Brand voice (3-5 adjectives, e.g., "warm, candid, slightly nerdy"):{{brand_voice}}- Customer profile:{{customer_profile}}- Forbidden words for the brand:{{forbidden_words}}(e.g., "luxurious, game-changing") Catalog parameters: - Description length per product:{{length_per_product}}(e.g., "60-90 words") - Bullet count per product:{{bullet_count}}(e.g., "3 short benefit bullets") - SEO note: include the primary keyword from each product's spec naturally, do not stuff Product spec sheet:{{product_specs}}For each product, output: - Product name (as provided) - Hero line (one sentence, lead with the strongest single benefit for{{customer_profile}}) - Description body (in the target word count, in the brand voice) - Three benefit bullets (short, scannable) - Specs block (technical specs from the input — bullet points, no rewriting) - SEO meta description (under 155 characters) Rules: - Do not invent features, materials, or claims that are not in the spec. - Do not use any word in{{forbidden_words}}. - Avoid clichés: "game-changing", "must-have", "revolutionary", "elevate", "curated". - Hero lines must vary across the set. Do not start three products in a row with the same sentence structure. - For any health, safety, or regulated claim (skincare, supplements, electronics safety), only use language directly supported by the spec — no implied claims. - Match the requested length precisely. Catalog consistency depends on it.

Tips for best results
- 1Always feed the prompt your forbidden words list. Brand voice consistency depends on excluding the catalog clichés that creep into every draft.
- 2Run the full set in one prompt rather than one product at a time. Cross-product consistency is the hardest thing to get manually.
- 3Have a merchandiser review every spec line before the descriptions go live. Descriptions inherit any error in the spec sheet.
- 4For regulated categories (skincare, supplements, electronics safety), pull a final pass through compliance. The prompt avoids implied claims, but jurisdiction-specific rules still apply.
- 5Track which hero-line patterns convert. After 50 products you will have a brand-voice pattern library that improves the next 50.
