The Digital Health Companion (DHC) is an AI-enabled chatbot designed to make accessing digital health resources more intuitive, personalized, and conversational. The DHC uses a Retrieval-Augmented Generation (RAG) approach that responds to a user’s questions by retrieving and generating relevant text content, based on the knowledge base added by the product’s developers. The topics selected for inclusion in the knowledge base include Interoperability, Digital Health Governance, Data Science/Health Informatics, Cybersecurity, Digital Health Financing and Procurement, Health and AI/Machine Learning, Maturity Toolkits, Electronic Medical Records, Digital Health Policy & Strategy, Data Standards, and Software as a Medical Device (SaMD). These topics were selected by members of the digital health collaborative.
