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.
Hi Product Hunt — I'm Jason, a one-person e-commerce company in London.
ProductJSON Studio exists because AI image models kept redrawing my own product. Same brief, a different lamp every re-roll — my Aetheo Aura table lamp would change its shape, its label, its proportions between shots. Plain-text prompts guess, and they guess differently each time.
A JSON prompt fixes that. It's a structured blueprint — product, scene, lighting, camera. Change one field and everything else stays anchored, so the product survives the re-roll. You can browse over three thousand example prompts and the whole guide with no key at all. Convert any idea into JSON, lock a saved product profile so its shape and label stay identical, and generate with Nano Banana 2/Pro or GPT Image 2, with A/B compare and batch. When a shot is right, the listings tool builds the rest — a compliance-first Amazon main image first, then the secondary set (lifestyle, exploded views, feature callouts, scale, box contents), or a brand-led PDP gallery for Shopify.
What it honestly is not: a hosted API. There's no signup and no card, and I'm not holding your keys — you bring a Gemini and/or OpenAI key, and it stays client-side in your browser. The studio is free forever. For people who'd rather own the thing, there's a full source licence.
I built the model-routing table by running a four-category, thirty-two-generation eval of Nano Banana Pro against GPT Image 2 (Beauty and Personal Care leaned GPT Image 2 for texture and label fidelity; general product leaned Nano Banana Pro). It's the tool I use daily for my own Amazon and Shopify listings.
Happy to answer anything about JSON prompting, the model eval, or running a product business solo.
