Write product descriptions with AI

Product descriptions are the copy nobody wants to write and everybody writes badly — a spec list dressed up with "high quality" and "premium." AI is genuinely good here, but only if you feed it real features and then tune it to your store's voice. Paste in "write a product description" with no specifics and you get generic filler that reads like every dropshipping store on the internet. Feed it actual specs and benefits and you get copy that sells. Fifteen minutes, and it scales across a whole catalog.

The trick is the order: generate persuasive copy from real features first, then tune the *tone* to your brand second. Skipping the tuning step is why AI store copy so often feels off-brand.

What you'll walk away with

• A persuasive description with a strong opening line and benefit-led bullets
• Copy tuned to your store's actual tone of voice
• A repeatable format you can run for every product
• Unique copy per product (which matters for SEO, not just reads)

Step by step, with the judgment that matters

1. Generate with ChatGPT — lead with benefits, not specs. Give it the product name and features and ask for a compelling opening line, three to five benefit-led bullets, and a call to action. The distinction that matters: a spec is "1,000mAh battery"; a benefit is "a full week between charges." Customers buy the benefit. Make the model translate every feature into what it does for the buyer.

2. Tune the tone with Shopify Magic. Paste the draft into Shopify Magic's product-description tool, select your store's tone of voice, and regenerate to match. This is what keeps a hundred products sounding like one brand instead of a hundred different AIs. If you're not on Shopify, do this pass in ChatGPT by telling it your brand voice with two example sentences.

A real run

For an insulated water bottle, ChatGPT opens with "Cold at hour twelve, still cold at hour twenty-four" instead of "premium stainless steel bottle," turns the vacuum-insulation spec into a benefit bullet, and closes with a CTA. Shopify Magic re-tones it to your brand's playful voice. Fifteen minutes, and it reads like your store wrote it, not a template.

Where it goes wrong

• Every product sounds identical. You reused one description. Give each product unique copy — it reads better and avoids duplicate-content SEO problems.
• It's a spec sheet, not a sell. You fed specs and got specs back. Explicitly ask for benefits, and give the model the "so what?" for each feature.
• The tone is off. You skipped the tuning pass. Always do the brand-voice step, or the copy floats free of your store's personality.

The honest cost

Free at the core. ChatGPT's free tier writes the descriptions. Shopify Magic is included with a Shopify plan (from ~$5/mo) — if you're not on Shopify, skip it and do the tone pass in ChatGPT for $0.
