In recent years, chatbots have become a common tool for banks and large companies around the world. Having human beings available to answer people’s questions and complaints can be costly, requiring many workers. And in most cases, employees can only work a set number of hours in a day, increasing the amount of time customers wait for a response. So not just companies, but a growing number of colleges and universities have also begun using chatbot technology, says Keith Rajecki. He is with Oracle Higher Education, a computer software company that serves these institutions.
