AI Product Description Cost Calculator

This free calculator estimates what it costs to generate product descriptions with AI using your own OpenRouter key. Set the length and how many products you have, pick a model, and see your cost per description and total — usually cents per product versus dollars with a copywriter.

Fast models like DeepSeek V4 Flash or Gemini Flash Lite are best for big catalogs.
Bring-your-own-key keeps large catalogs cheap versus per-word or per-credit tools.

How much does an AI product description cost?

With a bring-your-own-key setup, a 150-word product description typically costs a fraction of a cent on a fast model. Even a 1,000-product catalog often comes in under a few dollars total — versus $3–$10 per description from a freelance copywriter.

Why bring-your-own-key wins for catalogs at scale

Product catalogs mean volume, and volume is where per-word and per-credit pricing hurts most. Paying OpenRouter's wholesale token price directly keeps big catalogs cheap. nativeWP is an AI content automation platform for WordPress that bulk-generates SEO articles with your own OpenRouter API key and auto-publishes or schedules them to WordPress and Shopify. So generating and publishing hundreds of descriptions stays affordable.

Tips for AI product descriptions that convert

Feed the model real attributes (materials, size, use case) so output is specific, not generic.
Keep a consistent tone and structure across the catalog.
Add Product schema so descriptions earn rich results — use our schema generator.
