Titles and descriptions for 2,000 auto parts on Mercado Livre rewritten with AI, plus a website for the brand.

technical lines in the catalog
The catalog covers five technical lines: steering, brakes, engine, suspension and transmission. Brands carried include Tenacity, which specializes in anti-vibration components and hydraulic engine mounts, and SH Taiwan.
In auto parts, buyers search by car, model year and part number. If a listing doesn't speak that language, it doesn't show up.
Rewriting 2,000 listings by hand would take months and come out inconsistent from one writer to the next. And the work goes beyond copy: each part has to be tied to the vehicle, the technical line and the terms buyers actually type.
The company also had no website of its own. Its entire digital presence depended on the marketplace.
Each product was automatically classified by technical line and compatibility. With that foundation, titles and descriptions were rewritten to include what buyers search for, and the listings were updated directly on the marketplace.
In parallel, Cortex IQ built longoparts.com.br: a catalog with search by category, a spec sheet with compatibility for every product, and checkout on Mercado Livre, where the business already runs.

Listings that can be found
Titles now include vehicle, part and application, which is how buyers search.
Standardized catalog
All 2,000 listings follow the same title and description pattern, regardless of who wrote each one.
A brand beyond the marketplace
The website gives Longo Parts an address that doesn't depend on Mercado Livre, without changing where the sale happens.

Longo Parts appears as a parts supplier on the website of Jean Auto Center, another Cortex IQ client.
"Our partnership with Cortex IQ was key to taking our digital presence to a new level."
