BigFlippa is an AI-powered sourcing tool for people looking to find and resell underpriced items. Instead of manually scrolling through listings, users describe what they want in plain English, set criteria such as brand, model, condition and maximum price, then choose a location and search radius. BigFlippa monitors listings on Facebook Marketplace, Craigslist and OfferUp, sending matching opportunities by text, email or both. Alerts include the asking price, an estimated market value, potential profit and a link to the seller, with the service reporting a typical alert time of about five minutes.

Users can create up to 20 watchlists, while the Pro plan supports overlapping search territories. BigFlippa is designed for a range of resale categories, including electronics, cars and trucks, power tools, bikes, golf and sports equipment, trading cards and furniture. Its pricing and profit estimates are intended to help users assess deals quickly, particularly when products have identifiable brands and model numbers.
