Many businesses today strive to find the best AI chatbot app and create a bot for their company that can deliver seamless customer support. Customer service AI chatbot are quite commonplace today. These bots have come a long way since the early days of rule-based systems.

Rule-based systems can be considered to be the very first step towards creating conversational AI. In such systems, developers would program a set of rules that the system shall follow in order to respond to user queries. Rule based chatbots needed extensive coding and maintenance, and were not able to handle complex or unpredictable scenarios. Machine Learning and Statistical Approaches subsequently played an instrumental role in the evolution of Conversational AI based chatbots. These technologies enabled machines to learn how to respond to queries efficiently on the basis of data collected from previous interactions.

With machine learning (ML), conversational AI systems are able to analyze expansive amount of data and subsequently identify patterns that allow them to provide more accurate responses. Such an approach helped build smarter bots that had the ability to improve communication with users over time. Statistical approach like natural language processing (NLP), on the other hand, involves entity extraction, part-of-speech tagging and sentiment analysis, which are vital to the development of modern day AI Bot Chat.

The emergence of neural networks has also brought about a significant transformation in conversational AI. In contrast to rule-based systems and machine learning methods, neural networks employ intricate algorithms capable of learning from extensive datasets, resulting in responses that are both more natural and contextually appropriate. Progress in Neural Language Models paved way for significant advancements in Conversational AI. A notable breakthrough includes the implementation of Generative Pre-trained Transformer (GPT) models, which uses unsupervised learning to enhance their language generation capabilities.
