- Tracks overpays and spending across stores and categories over repeated purchases.
Key features

CartAssistant, a chat feature for asking about cheaper options, savings, shopping lists, and where to shop. What makes it different CartLens says its price data comes from receipts scanned by local shoppers rather than web scrapers or delivery-app markups. Each additional scan is presented as contributing to the local price data available to the community.

Problems Solved Consumers face several challenges when shopping in physical stores: No reliable way to compare in-store prices before or after purchasing. Significant price differences between nearby retailers. Promotional discounts that may still be more expensive than competitors' everyday prices. Budgeting apps that track spending but do not evaluate whether purchases were competitively priced. Online price comparison tools that rely on e-commerce or delivery prices instead of actual in-store shelf prices. CartLens addresses these challenges by providing transparent, data-driven price intelligence based on real shopping behavior rather than advertisements or estimated pricing.
Our Solution CartLens converts shelf tags and receipts into useful price information before and after a purchase. With anonymized crowdsourced sharing enabled by default, scanned prices improve the Geospatial Lattice. Users can turn sharing off in Settings. Where matching local data is available, CartLens enables users to: Check whether a price is fair before buying or after checkout. Discover lower-priced nearby stores. Identify hidden overpayments. Compare prices across multiple retailers. Track long-term spending performance. Make better purchasing decisions on future shopping trips.
The result is a smarter shopping experience built on transparency, community participation, and artificial intelligence.
