Finding products is easy. Knowing the difference is the work.

A listing is not a decision

A title, a photo and a price get a product into search results. They don't say whether two listings are the same item, whether the configurations match, or which differences matter.

Coreplex answers those first: what the product is, which variant is selected, who sells it, what the source actually says, and what can fairly be compared.

Breadth, with category depth

Baby, home and kitchen, travel, health and beauty, tech and pets, led by brands chosen from real shopper demand. A suitcase and a supplement don't share decision criteria, so comparisons follow the category.

Supplements are the deep vertical. Kato, our guided supplement experience, works at the level of ingredient, form and serving.

Built by an operator

Founded by Joe Pizarro: more than 15 years at iHerb, hands-on across catalogs, marketplaces, merchandising and regulated product content.

His validation tool, FeedZip, came from the same lesson Coreplex is built on: available data is not automatically accurate, complete or fit for where it appears.

One foundation, two interfaces

Shoppers use the website. Agents use the public MCP server. Both read the same product, seller and offer data under the same rules for what counts as the same item.
