Human-computer interaction has paved the way for large-scale natural language processing techniques. A chatbot in medical field  does instant research on people’s problems and prescribes medicine and assistance without any delay . This system proposes a medical assistant chatbot that uses NLP concepts such as cosine similarity and TF-IDF approaches to replay to users, which will be pocket friendly, fast, accurate and a one place halt for a user to avail home remedies and easy cures for common diseases.
