A chatbot is a conversational application that resides in a messaging platform like Facebook Messenger, Skype, Slack, Telegram and others. These are channels where the customers/users hang around frequently.
A bot can be installed quickly on a messenger application as simply as adding a new friend. It is a one-stop interface that keeps users away from hassles of navigating through apps. It allows users to handle several threads of conversations and apps simultaneously. Customers are used to messaging apps for day to day conversations. Chatbots make it easier for them to interact with service representatives with the same amount of comfort.
