What is a chatbot? | Chatbot

A chatbot or chatterbot is a software application that simulates human conversation through voice commands or text chats or both. Chatbots are a form of artificial intelligence (AI) used in messaging apps. These tools are automated programs that interact with customers like a human would and cost little to nothing to engage with. Chatbots generally work in two ways- either through machine learning or with set guidelines.

The term “ChatterBot” was originally coined by Michael Mauldin in 1994 to describe these conversational programs. There are a number of synonyms for chatbot, including “talkbot”, “bot”, “IM bot”, “interactive agent”, or “artificial conversation entity”. Most chatbots are accessed online via website popups or through virtual assistants. Some examples of chatbot technology are virtual assistants like Amazon’s Alexa and Google Assistant, and messaging apps, such as WeChat and Facebook Messenger.

Types of chatbots
