ChatRTX is a demo app by Nvidia that lets you personalize a GPT large language model (LLM) connected to your own content—docs, notes, images, or other data.

Leveraging retrieval-augmented generation (RAG), TensorRT-LLM, and RTX acceleration, you can query a custom chatbot to quickly get contextually relevant answers. And because it all runs locally on your Windows RTX PC or workstation, you’ll get fast and secure results.
