To lead healthy lifestyle healthcare is very much important. In few unsocialized areas, it is quite hard to find a consultation with a doctor that easily regarding health issues. The main idea here is to make a healthcare chatbot based on Artificial Intelligence using NLP that can diagnose the disease and provide required details about the specific disease before consulting or visiting a doctor. Reduces the healthcare costs and improves accessibility to this medical chatbot. Specific chatbots act as virtual medical assistance, which helps the patient know more about their disease and helps to improve their health. The user can achieve the real benefit of a chatbot only when it can diagnose all kinds of diseases and provide the necessary information. A text-to-text medical chatbot involves patients in online conversation considering their health problems which provides a set of personalized diagnoses based on their provided symptoms. These bots connect with the potential patients visiting the site, helping them discover specialists, booking appointments, and getting them access to correct treatment. This chatbot uses Natural language processing techniques to process and analyze the data and give the output inappropriate manner. It brings up the disease-related problems about whether the task mentioned above should be assigned to human staff. This healthcare chatbot system will provide patients healthcare support online at all times. It helps to generate health data and automatically delivers the information of reports to medical management. By asking the questions in series it helps the patient by guiding what exactly the user is looking for queries. Keywords —Artificial Intelligence, Machine Learning, NLP, text-to-text, chatbot, healthcare. ----------------------------------------************************---------------------------------- I. INTRODUCTION The Current artificial intelligence has developed to a point where programs can learn by the humans and effectively simplistic human conversations which is essential. One of the best-known examples of chatbots in recent history is Siri the AI assistant that is part of Apple's standard software for its products. Siri took chatbot mainstream in 2011. Since then, brands in every sector have started to use them, eventually developing a new trend conversational in user experience. This refers to an end-user experience in which your interaction with a firm or service is automated based on user prior behaviour. If users are developing artificial intelligence applications like Alexa, which enables the use of voice to control devices. If you are a user, you can already interact with this Artificial Intelligence chatbot on popular messaging platforms like Facebook, Instagram and so on. RESEARCH ARTICLE OPEN ACCESS
