Phia is a Chrome extension that answers a simple question as you shop: am I about to overpay? Click the "Should I Buy This?" button while viewing a product and Phia compares that item against real-time listings across retail and secondhand marketplaces, then shows cheaper options without taking you off the page. Its database covers hundreds of millions of secondhand items and more than a hundred resale partners, including large platforms like The RealReal, eBay and Poshmark. Beyond price matching, it tracks saved items and reports when prices drop, and surfaces resale-value context so you can judge whether a purchase holds up over time.
