CartLens

CartLens is a mobile-first pricing intelligence platform that transforms ordinary shopping receipts and price tags into actionable, location-based market data. The product addresses a fundamental inefficiency in physical retail: the lack of price transparency that causes millions of consumers to unknowingly pay different prices for identical products based solely on where or in which neighborhood they shop. Unlike online shopping, where instant price comparison across multiple retailers is standard, physical shopping has remained opaque, leaving consumers unable to determine whether a purchase represents good value. CartLens solves this by combining AI-powered receipt recognition, Optical Character Recognition (OCR), machine learning, and location-based analytics to extract product information, normalize item names across different retailers, and compare prices using verified, real-world purchase data from nearby shoppers. Within seconds of scanning a receipt or price tag, users receive personalized insights including whether they overpaid, the exact amount they could have saved, which nearby stores offer better prices, and recommendations for future purchases. The platform is designed for any consumer who shops in physical stores across any category, from groceries and household essentials to electronics and clothing. As more shoppers contribute anonymous receipt data, CartLens continuously builds a comprehensive retail pricing network that improves the accuracy of local price comparisons while helping the entire community make smarter purchasing decisions. Privacy is a core priority, with SOC2 compliant infrastructure, automated anonymity features, and full GDPR/CCPA compliance ensuring users retain complete control over their personal data.

Instant Receipt Scan

Point your camera at any receipt or price tag and CartLens instantly reads every item, price, and quantity with 99.8% accuracy. The AI-powered OCR engine processes the image in real-time, extracting product names, prices, weights, and quantities while normalizing item names across different retailers for accurate comparison. This eliminates the need for manual data entry and provides immediate feedback on whether you paid a fair price.

Basket Comparison

Compare your full shopping list across multiple local stores simultaneously to find the cheapest combination in real-time. CartLens analyzes the total cost of your basket at each nearby retailer, factoring in item-level price differences, and presents a clear side-by-side comparison showing exactly how much you could save by switching stores. The platform identifies the optimal shopping strategy, whether that means visiting a single store or splitting your list across multiple locations.

AI Shopping Chat

Ask CartAssistant anything about your purchases, pricing trends, or shopping strategy. This conversational AI tool finds cheaper alternatives to items you regularly buy, tracks your cumulative savings over time, and provides personalized recommendations on where to shop based on your specific buying patterns. CartAssistant learns from your Spending DNA to deliver increasingly relevant insights with each interaction.

Price Spike Alerts

CartLens continuously monitors pricing data from your local shopping network and detects sudden price spikes at specific stores. When the platform identifies an item priced significantly above its normal range or compared to nearby alternatives, it sends an immediate alert so you can avoid overpaying. This proactive feature protects consumers from temporary price increases due to supply issues, promotional resets, or pricing errors.

Weekly Grocery Planning

Before heading out for your weekly grocery run, scan the prices of staple items at your usual store. CartLens immediately compares these prices against data from other shoppers at nearby supermarkets, revealing which store offers the best overall value for your specific shopping list. You can then plan your route to visit the most cost-effective stores, potentially saving 10 to 20 percent on your weekly grocery bill.

Travel Shopping Optimization

When traveling to a new city or country, CartLens automatically adapts to local currencies, languages, and measurement units. Cross a border and the app instantly syncs to display prices in the local currency with native language support. This allows travelers to quickly assess whether items at tourist-oriented shops are overpriced compared to local stores, ensuring they pay fair market rates wherever they shop.

Household Budget Auditing

Use CartLens to conduct a comprehensive audit of your household spending over time. The platform tracks every scanned receipt, categorizes spending by store and product type, and identifies patterns of overpayment. With the detailed spending breakdown showing essentials, shelter, and other categories, users can pinpoint exactly where their money is going and make data-driven decisions to reduce monthly expenses.

Price Verification Before Major Purchases

Before making a significant purchase like electronics, appliances, or furniture, scan the price tag in-store. CartLens instantly compares the listed price against real purchase data from other shoppers at nearby retailers, revealing whether the item is priced competitively. This prevents impulse overpayment and ensures consumers make informed decisions on high-ticket items where price differences between stores can be substantial.

How does CartLens protect my privacy when I scan receipts?

CartLens uses SOC2 Type II compliant infrastructure and employs automated anonymity protocols that scrub personally identifiable information (PII) from every scan. Your identity is decommissioned with a single click, and the platform removes all PII while keeping the price data active for community benefit. The system is built with sovereign privacy policies, including full GDPR and CCPA compliance, ensuring you retain complete ownership and control over your personal data.

How accurate is the receipt scanning technology?

CartLens achieves 99.8 percent accuracy in reading every item, price, and quantity from receipts and price tags. The platform uses a proprietary multimodal clustering engine called Matryoshka, powered by Gemini Embedding 2, which fuses raw pixel data with semantic text strings into a single 768-dimension vector. This advanced approach ensures that even poorly printed or damaged receipts are processed accurately, and item names are normalized across different retailers for reliable comparison.

Where does the pricing data come from?

All pricing data in CartLens comes from real shoppers scanning their actual receipts and price tags. The platform does not rely on web scrapers, outdated merchant APIs, or delivery app pricing. Every scan contributes to a ground-truth geospatial pricing network that grows in accuracy and density with each contribution. This crowdsourced approach ensures the data reflects actual prices paid by real consumers at physical store locations near you.

Can I use CartLens internationally?

Yes, CartLens offers full native support for 11 languages, including English, Japanese, Arabic, French, and others. The app automatically adapts to local currencies and measurement units when you cross a border, providing a seamless zero-friction experience. Whether you are shopping in the United States, Kenya, Japan, Saudi Arabia, or France, CartLens adjusts instantly to display prices in the local format while maintaining all core functionality.
