How we’ve been interacting with technology has altered with the presence of chatbots, which have now become a part of our digital society. These artificially intelligent virtual personal assistants are being applied on a vast scale in customer services, health care, and education sectors since they are capable of answering the customers, addressing their queries, and directing them in real-time. In relation to their application in healthcare, in this research study, the history of chatbots is discussed, the technology employed by them, their real-world applications, and the problems faced by them. Modern-day chatbots can understand human language, learn from past conversations, and communicate in a customized way by employing Natural Language Processing (NLP), Machine Learning (ML), and Artificial Intelligence (AI). They may be anything from AI-based chatbots able to engage in meaningful, dynamic conversations to rule-based assistants that utilize pre-defined scripts. With the advent of technology, chatbots are increasingly being applied in the field of health care such as patient assistance, mental assistance, and diet and nutrition guidance, all of which enhance access to health care services. However, despite all their benefits, their potential is also hindered by limitations such as privacy, ethical concerns, and the inability to understand human feelings. As the future of deep learning, IoT connectivity, and more interactive AI is on the horizon, chatbots appear to have a very bright future. The purpose of this research is to give an authoritative and illuminating perspective on how chatbots are changing various businesses and the future of AI communication.
