About

I run a solo e-commerce business (Amazon, TikTok Shop and Shopify) and build the tools it needs — image generation, feed diagnostics, content automation — then package the ones worth sharing. ProductJSON Studio is the image tool: consistent product photography from JSON prompts, free with your own key. I share the whole build in public on the One-Person E-Commerce Co YouTube channel.

ProductJSON Studio - Consistent AI product images for e-commerce. Free, BYOK.

The same product in every AI shot, not a fresh guess each re-roll. Turn any idea into a JSON blueprint — change one field, the rest stays anchored. Build listing-ready sets for Shopify and Amazon. Free: browse with no key, add your own to generate.
