LemMeBuyIt is a real-time product intelligence platform that continuously refreshes pricing, availability, price movement, and historical trends across more than 100 U.S. retailers. It delivers this data to shoppers, brands, resellers, and AI agents through a browser extension and model context protocol (MCP) for tools like Claude, Cursor, Grok Bot, and ChatGPT. The platform maps retailer products to standardized identifiers like Amazon ASINs, UPC and GTIN, and eBay listings to offer unified cross-retailer comparisons. Users can analyze historical pricing to evaluate discounts, track inventory and stock changes, and query catalogs by brand, category, and price. Plans range from a free tier with basic shopping search and limited compares to Extension Plus at $49.99 per month, and MCP Standard and Pro tiers for automated AI workflows.
