Addressing AI-Generated Outfit Mismatches
A key challenge is matching AI-generated ensembles that may not exist exactly in the catalog. LookSync overcomes this by using deep visual embeddings, scalable vector search, and reranking to provide relevant alternatives in real-time, bridging the gap between synthetic generation and tangible product discovery.
Real-time Product Discovery for AI Avatars
Glance AI users can upload selfies to create avatars and try on AI-generated looks. LookSync ensures every AI look is shoppable by finding the closest visual and semantic matches from a 12M+ product catalog, even if the exact AI-generated item isn't available. This enhances the immersive shopping experience, driving higher user engagement and conversion.
