AI Haggler is a web-based application that utilizes artificial intelligence to call hotels and negotiate discounts for last-minute bookings. Users can input hotel phone numbers, select their preferred language, and set negotiation preferences. The AI agent then contacts the hotels to inquire about room availability and negotiate better rates. After the calls, users receive detailed reports with the results, enabling them to make informed booking decisions. This service streamlines the process of securing discounted accommodations, saving users time and effort.
