A full image set for every listing in your catalog
Cobalt12 turns the photos your sellers already have into complete image sets: a clean main image and a gallery that shows the product in use, its size and what it is made of, captioned in your marketplace’s language. For marketplaces, retailers and agencies with large catalogs.
No public price list: we quote by volume, after a pilot on your own listings.
What Cobalt12 does for a catalog
Full image sets
Seven frames per listing from the photos it already has: the main image on pure white, the product in use, infographics, dimensions and close-ups. Each set is planned for its product, and its captions use what is printed on the product and what the listing says.
Photo cleanup to your rules
Captions, banners, logos, watermarks and seller contacts added on top of a photo come off, while what is printed on the product itself stays. The cleanup follows your marketplace’s photo rules.
Captions in your language
Headlines and captions on the images are written in your marketplace’s language, such as English or Ukrainian.
Amazon listings for brands and agencies
For teams that sell on Amazon: the images and every listing field, drafted from the brand’s Seller Central data and validated by Amazon before anything is published.
From one phone photo to a full set
A multivitamin photographed on a desk with a phone, and the seven frames Cobalt12 made from that photo.








A kitchen-shelf photo, made into a main image
The same bag and label on a pure white background, ready for a marketplace’s main-image rules.

Built to keep the product true
The product stays the product
Every frame starts from the listing’s own photos. Shape, colour, label and quantity carry over, and the scene changes around them.
Captions from facts
Captions draw on what is printed on the product and what the listing says, not on guesses about it.
Every frame explained
Each frame comes with its plan: what it is for and which facts it uses, so a reviewer can check it quickly.
Frames you choose
Sets are planned per product, and you can require the frames every listing must have, such as dimensions.
Delivery that fits your catalog
Send listings as a feed or as files with their photos and data, and get finished images back named and sized for your catalog. Whether that runs as a file exchange or an API connection is agreed during the pilot.
Your data stays yours
Photos and listing data are used only to make your images. They are not used to train AI models, ours or anyone else’s.
Cobalt12 is run by CobaltAI OÜ, a company registered in Estonia, in the EU. Images are made with OpenAI’s models through its API, which does not train on API data.
Pricing on request
The price depends on volume, image size and quality, and how many frames each listing needs. We quote after the pilot, from your own listings rather than a guess.
