Introduction

White-box vehicle valuation Chrome extension providing evidence-based pricing insights with comprehensive market analysis for US and UK markets.

The MarketCheck Chrome Extension puts vehicle valuation and market analysis directly into your browser. Instead of bouncing between multiple tools, you can see pricing insights, market trends, and detailed specifications right on the car listing pages you’re already browsing.

Think of it as a white-box pricing tool. Unlike traditional black-box valuations that only show a number with no explanation, MarketCheck shows you the “why” behind the number—using real market evidence, live comparables, and historical data.
