CartLens
AI-powered "Intelligence Layer" for physical commerce
CartLens is a high-fidelity, AI-powered shopping companion designed to transform physical shopping artifacts into structured digital intelligence. We bridge the high-friction gap between physical receipts and digital financial tracking using a cost-optimized, multimodal AI stack. Most consumers suffer from "Spending Blindness"—they know where they spent money, but they have no unified, product-level visibility into what they bought and how those prices fluctuate across different merchants.
👋 Hey Product Hunt! I’m Chris, the creator of CartLens.
Most budgeting apps feel like an autopsy. They tell you why your bank account "died" at the end of the month, but they don't help you survive while you're actually at the store.
I built CartLens to give consumers a high-fidelity "Intelligence Layer" for physical commerce. We’ve moved past simple OCR into what I call Spending DNA—using Google Gemini to convert raw visual fragments (receipts, product images, and price tags) into a structured, geospatial intelligence lattice.
Why CartLens is different:
The Vision-to-State Heuristic: We use gemini-2.5-flash to parse SKUs and prices with surgical precision in real-time.
CartAssistant: Your persistent AI sidekick that doesn't just "chat," but actually orchestrates your cart optimization.
The Global Lattice: A crowdsourced map of verified local prices. If you find a better price, you're not just saving money—you're updating the "floor" for your entire neighborhood.
I’ll be here all day to answer questions about the AI routing layer, our "Leakage Protocol," or our roadmap for agentic commerce.
