Most shopping tools chase coupons. Dupely tackles trust. Online shopping is full of manipulation: artificial price drops, fake reviews, paid influencers, and sketchy white label sellers reselling the same product at a markup. DupeScore finds identical products for less. Trust This Price flags fake savings using 90 days of price history. Seller badges show you who's actually credible. Now on iOS, Android, and Chrome. Dupely is the trust layer online shopping has been missing.

Could you build this?
Partial While a browser extension frontend comparing shopping links is easy to build, accurately identifying identical white-label/dropshipped products across thousands of e-commerce sites requires web scraping at scale and multimodal visual/catalog matching.
What it would actually take: A production version requires an ingestion pipeline scraping major marketplaces (Amazon, AliExpress, Shein, Shopify stores) with proxy rotators and anti-bot bypasses. Matching needs visual embeddings (CLIP or specialized product vision models) combined with text embeddings to link disparate seller listings. The browser extension queries this indexed catalog database via a low-latency vector search API.
