Chat with RTX is an NVIDIA demo application that allows users to create a personalized AI chatbot by connecting it to their own data sources, such as documents, notes, or video transcripts. Using retrieval-augmented generation (RAG), TensorRT-LLM, and RTX acceleration, the tool provides quick and contextually relevant answers from the custom chatbot, running locally on Windows RTX PCs or workstations for fast and secure results. People might want to use Chat with RTX for enhanced productivity, to streamline access to information, or to integrate a bespoke conversational AI into their workflows without the need for cloud processing.
