With an unprecedented increase in the number of people using messaging apps today, and the advancements in Artificial Intelligence, Machine Learning and Natural Language Processing (NLP) technologies, the rise of chat bots seems to have been inevitable. Research shows that the number of people using chat apps has surpassed the number of those using social networking apps, which is believable yet surprising! Facebook Messenger claims to have recently hit the much coveted'billion' with 1.2 billion users on the platform. Last year, at Facebook's Developer Conference, F8, the support for bots on Messenger platform was unveiled. And since then, developers from around the world have been working to leverage the next-gen technology.
