CHENNAI: Ever logged onto an e-commerce website and felt confused on what to buy or where to go? To ease the process and deliver a better shopping experience, companies are investing heavily in artificial intelligence (AI) and machine learning. The startup uses AI to understand the semantics of websites along with the relations a product has with its pricing, discounts, etc and leverages those relations to find out the best deal (or coupon) available across any e-commerce site. So, how is Grabshack different from other price comparison website? Rajat explains, "We search live/real time across hundreds of ecommerce sites (like Google), while other deals and coupons sites in India manually enter deals and coupons on their site (curated list) from which they search."
