Chatbot is used extensively to check the state of health at any time. It is the same as going to a doctor and having the medication prescribed. This paper discusses about medical chatbot using the machine learning algorithm which predicts the accuracy of the disease. There are many machine learning algorithms that can be used to predict the disease. Support Vector Machine learning technique is primarily used to achieve precise prediction and boost the efficiency of the model. The system uses Natural Language Processing to achieve the style of chatting. Using this approach people can reduce spending time in hospitals and receive low cost or cost-free services. © 2021 Institute of Physics Publishing. All rights reserved.
