This high-tech E.L.F. is guiding confused shoppers with the help of IBM's Watson

It's essentially a mobile concierge, an IBM Watson-powered chatbot that asks people things like what they enjoy doing or how long they plan to hang out at the mall, according to VentureBeat. You can chat with the bot through Facebook Messenger or online at elf.mallofamerica.com. The Mall of America, located in Bloomington, Minnesota, is a massive collection of hundreds of stores across 5.6 million square feet, so E.L.F. could be a big help in narrowing down options and getting around. It's just one of multiple "helper bots" developed by IBM Watson Group and Satisfi, which has called concierges like E.L.F. "Imagine doing all of your shopping from home, and when you do have to go into a store there is a personalized shopper ready to wait on you, and somehow all of this is given to you at no added cost," Satisfi wrote in a blog post.
