Watson powers the company's chatbot GWYN (Gifts When You Need) and helps it detect user tone. GWYN interacts with online customers using natural language and is designed to understand human intention behind each purchase by interpreting and asking several questions. Last year, an AI teaching assistant powered by IBM Watson helped moderate an online forum for a computer science class at Georgia Tech University, and most students didn't find out they were interacting with AI. IBM Watson did a pilot with the Australian government around Nadia, a virtual assistant platform that helps disabled people get information about government services.
