ChatGPT Prompts for Product Descriptions (2026): 26 Prompts by Goal and Platform

The best ChatGPT prompts for product descriptions give it three things: your product facts, the platform and its limits (Amazon titles up to 200 characters, Etsy 140, eBay 80), and one rule: “use only these facts; write [ADD] where something is missing.” Below are 26 copy-ready prompts, grouped by goal and by platform.

If you'd rather skip prompting, our AI product description generator writes two options per marketplace from your facts. This guide is the deeper version for ChatGPT, Claude or Gemini: a base prompt to reuse, prompts for each job, guardrails that stop the AI inventing claims, and a checklist before you publish.

What makes a good ChatGPT prompt for product descriptions?

A good prompt sets a role, gives facts, names the platform and length, sets the tone, and forbids invented claims. Missing any one of these is why ChatGPT descriptions sound generic or promise things the product can't do.

The base prompt to reuse for every product

Save this and swap in the platform and facts. Every prompt below builds on it.

You are an e-commerce copywriter. Write a product description for [platform] using only the facts below. Length: [X] words. Audience: [who]. Tone: [tone]. Open with the main benefit in one sentence, then the details a buyer checks (size, materials, use, care, what's included). Don't invent reviews, results, statistics, certifications, awards or health claims. If a fact a buyer would need is missing, write [ADD]. Facts: [paste fact block]

ChatGPT prompts for product descriptions by goal

Each prompt assumes you paste the base prompt or fact block first.

1. Benefit-led: “Rewrite this so the first sentence says what the product does for the buyer, not what it is. Keep every fact.”
2. Short version: “Write a 40–60 word description for mobile shoppers. Most important detail first.”
3. Long version: “Write a 200–250 word description with three short sections: what it is, how to use it, specs and care.”
4. Bullet points: “Turn these facts into 5 bullets. Each starts with a 2–4 word benefit in capitals, then the supporting fact.”
5. Specs table: “Turn these facts into a two-column spec table (Feature | Detail). Write [ADD] for anything a buyer would expect but I haven't given.”
6. Audience rewrite: “Rewrite this description for [audience]. Change the examples and tone, not the facts.”
7. Tone options: “Give me three versions: plain and practical, warm and personal, premium and minimal.”
8. Answer objections: “List the 5 questions a hesitant buyer would ask about this product, then answer each using only the facts. Write [ADD] where I need to supply the answer.”
9. Gift angle: “Write a version for gift buyers: who it suits, the occasion, what arrives in the box. No claims about delivery dates.”
10. Sensory detail: “Add one or two sentences on how it looks, feels or smells, using only the materials and finishes listed.”
11. SEO keywords: “Work these phrases in naturally, each once at most: [phrases]. Don't stuff them; readability comes first.”
12. Tighten: “Cut this to [X] words without losing any fact. Remove filler words and stock phrases.”
13. Variants: “Rewrite this for the [color/size] variant, changing only the details that differ.”

ChatGPT prompts for product descriptions by platform

Each marketplace has different limits and rules, so name the platform and put the numbers in the prompt. Our listing character limits guide has the full list.

14. Amazon title: “Write 3 Amazon titles under 200 characters: brand, product type, key feature, size or quantity, color. No promotional words, no word more than twice, none of these characters: ! $ ? _ { } ^.”
15. Amazon bullets: “Write 5 Amazon bullet points, each under 250 characters, plain and factual. No pricing, shipping or promotional claims such as “best seller”.”
16. Amazon description: “Write an Amazon description under 2,000 characters in plain text with short paragraphs. No HTML, no claims I haven't supplied.”
17. Etsy: “Write an Etsy description in first person as the maker: opening line, how it's made, a list of size, materials and care, then personalization and processing time.”
18. Shopify: “Write a Shopify product description: one benefit-led opening sentence, a short paragraph, then 4–6 bullets. Also write a meta description of 150–160 characters.”
19. eBay: “Write an eBay title under 80 characters with brand, model, key spec and condition, then a description that states condition clearly, including any flaws: [list flaws].”
20. Walmart: “Write a factual Walmart description and key features list. Plain language, no promotional or comparative claims.”
21. TikTok Shop: “Write a short TikTok Shop description: first line under 15 words that hooks, then 3 short benefit lines with facts. Casual tone, no exaggerated claims.”
22. Instagram caption: “Turn this description into an Instagram caption under 100 words with one question to prompt comments and 5 relevant hashtags.”
23. Google Shopping title: “Write a product title for a Google Shopping feed under 150 characters, most important details first: brand, product type, attributes.”
24. Wholesale line sheet: “Write a 30-word line-sheet description for retailers: what it is, materials, size, pack quantity. No consumer marketing language.”
25. Bundle: “Write a description for a bundle of [items]. List exactly what's included, then why they work together.”
26. Translation: “Translate this description into [language] for shoppers in [country]. Keep units and sizes accurate; flag any phrase that doesn't translate well.”

Marketplace character limits and title rules were checked in October 2026. Marketplaces change their rules, so confirm the current requirements in your seller dashboard before you upload a large batch.

How do I stop ChatGPT from inventing product claims?

Tell it not to, give it every fact it needs, and check the output against your fact block. Invented claims are the biggest risk of AI product copy: a false “waterproof” or “hypoallergenic” can cause returns, marketplace takedowns or worse.

• Health and safety: no “non-toxic”, “cures”, “safe for babies” or medical benefits unless you hold the evidence.
• Certifications: no organic, FDA, CE, BPA-free or similar unless you have the paperwork.
• Performance numbers: battery life, capacity, coverage and durability only from your testing or the manufacturer's spec.
• Social proof: no invented reviews, ratings, “bestseller” or “loved by thousands”.
• Comparisons: no “better than [brand]” claims.
• Eco claims: no “sustainable” or “eco-friendly” without specifics you can back up.

Checklist before you publish an AI description

1. Every fact matches your fact block; no [ADD] left in the text.
2. No health, safety, certification or performance claims you can't prove.
3. Title and bullets fit the platform's limits (checked with a counter).
4. The first sentence says what it is or what it does for the buyer.
5. Stock phrases removed: “elevate”, “seamless”, “game-changer”.
6. Read aloud once. If it doesn't sound like your brand, edit it.

Is ChatGPT or a product description tool better?

ChatGPT is free and flexible; a dedicated tool saves the prompt setup. If you write a few descriptions a month, the prompts above in free ChatGPT are enough. If you write many, a tool that already knows each marketplace's style saves time. AiArter's listing copy writer (ours) writes titles, descriptions, bullets and ad copy per marketplace, uses only the facts you give, and can follow a brand kit's tone. It uses credits, so ChatGPT is the cheaper choice for occasional use. Our guide to writing product titles covers titles in more depth.

Frequently asked questions

What is the best ChatGPT prompt for product descriptions?

Give ChatGPT a role, your product facts, the platform and length, the audience and tone, and the rule “use only these facts; write [ADD] if something is missing”. That last line stops it inventing details.

Can ChatGPT write Amazon product descriptions?

Yes. Tell it the limits (titles up to 200 characters in most categories, 5 bullets) and ban promotional language and unproven claims. Check the result against Amazon's style rules for your category.

Is it allowed to use AI-written product descriptions?

Major marketplaces don't ban AI-written copy, but you're responsible for accuracy. False claims break marketplace rules and consumer protection law whoever wrote them.

How do I make ChatGPT descriptions sound less generic?

Give it specific facts, a defined audience and a tone, then ask for three versions and edit the best one. Cut stock phrases and add one detail only you would know.

How long should a product description be?

Most products do well with 50–150 words, plus a specs list. Technical or expensive items can justify more; mobile shoppers skim, so lead with the key detail.

Can ChatGPT write product descriptions from a photo?

It can describe what it sees, which helps with visual words, but it can't confirm materials, sizes or performance. Use photo descriptions as a draft and supply the facts yourself.
