It aims to develop knowledge and familiarity of AI among primary care physicians.PubMed and Google searches were performed using the key words 'artificial intelligence'. Further references were obtained by cross-referencing the key articles.Recent advances in AI technology and its current applications in the field of medicine have been discussed in detail.AI promises to change the practice of medicine in hitherto unknown ways, but many of its practical applications are still in their infancy and need to be explored and developed better. Medical professionals also need to understand and acclimatize themselves with these advances for better healthcare delivery to the masses.
