Writing product descriptions by hand is slow, and generic AI chatbots don’t know your catalog, your store platform or your SEO keywords. Dedicated AI product description generators fix that: they import your products, write descriptions in bulk and push them back to your store.
We compared the leading options on what matters for an online store: price per product, bulk generation, store integrations and languages. Here’s what we found.
How we compared these tools
This is a research-based comparison. We reviewed each tool’s official pricing page and documentation (checked November 14, 2026) and scored them on four criteria:
- E-commerce fit: is it built for product content, and does it connect to your store?
- Value for money: price per product or per month, free plans and trials
- Scale: bulk generation, catalog import/export and languages
- Transparency: clear public pricing and documentation
Prices and features change often. Always confirm the current price on the vendor’s site before you buy.

Pricing in detail

|---|---|---|---|
| Describely | $0.75 per product (up to 500 products) | First 5 products free | Pay as you go; custom for 500+ SKUs |
| Smartli | $39/mo (Starter, 20 descriptions) | 7-day free trial | Monthly or yearly (Pro $24/mo yearly) |
| Hypotenuse AI | Custom | Free trial (Basic) | Contact sales |
| Jasper | $59/seat/mo yearly, $69 monthly | 7-day free trial | Per seat |

Tip: if you have a one-off job — for example rewriting 200 old descriptions — pay-per-product (Describely) is usually cheaper than a subscription you forget to cancel. If you add new products every week, a subscription (Smartli) can work out cheaper.
What to look for in an AI product description generator
- Store integration. Copy-pasting hundreds of descriptions defeats the purpose. Look for a direct Shopify or WooCommerce connector, or at least CSV import and export.
- Bulk generation. Check whether bulk is included in your plan — with some tools it’s only on the most expensive tier.
- Brand voice. The best tools learn from your existing copy so every product sounds like your store, not like a robot.
- Languages. Selling in several countries? Test your target languages in the free trial; quality varies a lot between languages.
- SEO controls. Keywords, meta titles and meta descriptions save you a second round of work.
How to get good results from any of these tools
- Feed it facts. Materials, dimensions, who it’s for and the problem it solves. AI can’t invent accurate specs.
- Start with 5 products. Use the free trial or free credits on your best-selling products and compare the results.
- Edit before publishing. Check every fact and add one detail only you would know.
- Avoid near-duplicate copy. Hundreds of descriptions with the same structure and phrases look low-effort to shoppers and search engines.

For most small and mid-size stores, Describely is the best fit because you pay per product ($0.75) with no subscription and it connects directly to Shopify. If you want a monthly plan, Smartli is the budget choice. Shopify Sidekick is a free starting point included with your Shopify plan.
Is there a free AI product description generator?
Shopify Sidekick is included with Shopify plans at no extra cost, though usage limits vary by plan. Describely lets you generate the first 5 products for free, and Smartli and Jasper offer 7-day free trials.
Will Google penalise AI-written product descriptions?
Google's guidance focuses on whether content is helpful, not on how it was produced. Use AI for the first draft, then check every fact, add details only you know (materials, sizing, how it feels in use) and avoid publishing hundreds of near-identical descriptions.
Which tool is best for selling in several languages?
Hypotenuse AI lists 40+ languages and Jasper 30+. Describely supports multiple languages but does not publish a full list, so test your target languages during the free trial.
How much does it cost to write descriptions for 200 products?
With Describely pay-as-you-go, 200 products cost about $150 once ($0.75 each). With Smartli, the monthly Empire plan ($99) covers up to 1,000 descriptions. Shopify Sidekick costs nothing extra if you are already on Shopify. Prices checked November 14, 2026.
