CartLens is a privacy-first shopping app built to help you stop overpaying. Point your camera at any receipt or price tag, and it reads items and prices in seconds with 99.8% accuracy. The app then shows you where nearby stores have the same items cheaper, based on real prices from real shoppers in your area — not web scrapers or delivery app markups.

The core mechanics are straightforward: scan, compare, save. Scan a receipt or price tag with your phone camera. CartLens compares your full basket across local stores and shows which combination of stores would be cheapest. It also tracks your spending patterns over time so you can see exactly where your money leaks across categories and stores. CartLens Assistant, an AI chat agent, helps you find cheaper alternatives and answers questions about your spending.

Built for anyone who shops: budget-conscious families, frequent travelers, regular price-watchers. The app works across 11 languages with instant currency and unit conversion when you travel. All infrastructure is SOC2 Type II compliant with GDPR/CCPA built in. You own your data — download it as JSON anytime or decommission your entire identity with one click.
