Write a batch of product descriptions in your voice

Today

Forty new SKUs arrive as a supplier spreadsheet of attribute codes and a folder of photos. You write six good descriptions on Monday, and by the twelfth you are copying the last one and swapping the color.

With Claude

You paste the spec rows once and get a first draft for every SKU in your format, with the title, the bullets, the long copy, and a flag on any claim nobody has verified yet.

The prompt

Paste this into claude.ai and replace anything in brackets.

You are writing product descriptions for my store. Match the voice in the examples below. Use only the attributes I give you.

Our voice, taken from five descriptions we are happy with: [paste five of your best existing descriptions here, or write SEE PROJECT KNOWLEDGE if you uploaded them]
Words and phrasings we never use: [list them, for example luxurious, must-have, elevate, perfect for everyone]
Who buys these and what they compare them to: [one or two sentences]
The products, pasted from our supplier sheet or PIM export: [paste the rows here, one product per line, with every attribute you have]

Rules that override everything else:
1. Never state a measurement, material, weight, care instruction, certification, country of origin, warranty term, or compatibility fact that is not in the data I pasted.
2. Never state stock levels, shipping times, delivery dates, or prices, even if the source sheet contains them. Write [STOCK], [SHIPS], or [PRICE] and I will fill them in from our system.
3. If an attribute is missing and the copy needs it, write [MISSING: what you need] instead of guessing.

For each product give me:
1. A product title under 70 characters, front loaded with what the thing actually is.
2. Four bullets, each one a concrete attribute and why a buyer would care about it, in that order.
3. A description of 90 to 130 words that opens with the problem this product solves, not with the brand.
4. A meta description under 155 characters.
5. Alt text for the main photo, describing what is visible rather than repeating the title.
6. A line called CHECK BEFORE PUBLISH listing every claim in your draft that a human should verify against supplier documentation.

Then, at the end, give me one list: every attribute you needed and did not have, grouped by product, so I can go get it once instead of forty times.

What to skip in ecommerce and retail businesses

  • Anything that depends on what your systems say right now. In a plain browser chat with no connectors, Claude cannot see your inventory, order status, tracking, carrier delays, live prices, or your storefront, so it must never state them. A description that says in stock and ships tomorrow, or a chargeback response that asserts a delivery date Claude cannot see, is worse than no draft at all. Keep those as bracketed placeholders that a person fills from the real system before anything goes out.
  • Product claims a human has not verified against supplier documentation. Claude will write a confident sentence about materials, certifications, country of origin, warranty terms, or compatibility because that is how product copy usually reads, and it has no way to know whether yours is true. Health, safety, supplement, cosmetic, and children's products are the sharp end of this: phrases like clinically proven, FDA approved, non-toxic, hypoallergenic, or BPA free carry real regulatory weight in the US. Draft with Claude, then verify every claim against the spec sheet or certificate before it is published.
  • Raw customer data. Strip names, email addresses, shipping addresses, phone numbers, and order numbers out of any export before you paste it, and never paste payment card details anywhere. You lose nothing analytically, because the useful signal is in what people wrote. Know your plan too: on Free, Pro, and Max accounts, whether your chats are used to improve Claude is a setting you control in Privacy Settings, while Team and Enterprise accounts sit under Anthropic's commercial terms instead.
