What is an AI Chatbot?

AI chatbot

A chatbot is a text or voice-based interface that is built and deployed on the website or apps to simulate a conversation with users and seamlessly support users. These are self-learning bots and are programmed with AI, NLP, and ML technologies. There are many benefits with these bots; they can automate tasks, understand words and phrases, frame appropriate responses, and can learn from the received inputs. Thus, these conversational bots are effectively being used to replace a repetitive task that a human would do. Moreover, AI conversational bots differ from traditional rule-based bots and can understand language outside pre-programmed commands.

Some of the predominant AI conversational bots include Alexa, Siri, Mitsuku – Pandorabot, Botsify, etc. These bots can perform various tasks such as conducting sentiment analysis, predicting consumer likes and dislikes, assisting the customer with the right product/service, etc. As businesses across industries continue to leverage AI conversational bots or agents, their dominance in the market is increasing rapidly in recent times.
