A Chatbot is nothing but a computer program that stimulates and processes written or spoken human conversation. This, in turn, allows humans to communicate and interact with digital devices in a similar manner as they interact with a real person. Chatbots are software applications like rudimentary programs that answer human queries like a live agent. The interaction between chatbots and humans is usually an online chat conducted via text or text-to-speech. The chatbot software helps automate customer conversations and communicate with them via messaging platforms.
