NanoPrice: AI price comparison, product price checker, and deal finder for Chrome. Compare prices while you shop online, find the lowest price for the product you are viewing, and open matching offers from other stores without leaving the page. Online prices change constantly. The same laptop, headphones, shoes, toy, kitchen item, beauty product, or home accessory can cost less in another store. NanoPrice helps you check before checkout by identifying the product page, matching the exact item with on-device AI, and comparing offers through Google Shopping. WHAT NANOPRICE HELPS YOU DO • Compare product prices across online stores. • Find the lowest price for the item currently open in your browser. • Discover better deals, sale prices, and cheaper matching offers. • Check whether the current store is actually a good place to buy. • Save time by replacing manual price searches and extra shopping tabs.
