The Challenge

An auto parts marketplace was struggling with slow, manual listing creation. Sellers snapped photos of parts but had to manually identify part types, research compatibility (make/model/year), write product descriptions, and create listings—often taking 15-20 minutes per part.

Listings were often incomplete, had poor SEO, and low CTR. They needed an AI solution to automatically classify parts from photos, match them to vehicle catalogs, and generate high-quality, SEO-optimized listings at scale.
