The short version: ChatGPT and Claude write the fastest first drafts, Describely and Shopify Magic are built specifically for bulk product descriptions, and Jasper is worth the money only if you’re running a real content team. The tool matters less than the prompt and the editing pass that comes after it, and I’ll show you both. Why product copy is the ecommerce job nobody has time for If you sell 300 SKUs and each description takes 20 minutes to write, that’s 100 hours of work sitting between you and a live store. Most people don’t have 100 hours, so the descriptions get copied from the supplier feed, or they get one paragraph that says “high quality material, perfect for any occasion” on every single product. I’ve seen stores lose search visibility because thirty of their competitors are using that exact same supplier feed copy, word for word.
