What is ChatRTX? It’s a demo application from NVIDIA that turns your Windows RTX PC or workstation into a local AI chatbot, capable of answering questions based on your own files and media. Designed with privacy, speed, and personalization in mind, ChatRTX integrates key NVIDIA technologies like TensorRT-LLM, NIM microservices, and RTX acceleration to deliver fast, accurate, and secure results right on your device.
Using retrieval-augmented generation (RAG), ChatRTX connects a powerful GPT-based large language model to your personal content—such as documents, images, and notes—allowing you to chat with your files and receive contextually relevant answers. There’s no need to upload anything to the cloud.
Chat with Your Files
ChatRTX supports a wide range of file formats including TXT, PDF, DOC/DOCX, JPG, PNG, GIF, and XML. Simply direct the app to your folder, and it will ingest and index the content within seconds. This means you can search and ask questions about your documents and images quickly and privately.
Talk to ChatRTX
Voice interaction is a standout feature. ChatRTX integrates automatic speech recognition (ASR) to support real-time conversation in multiple languages. Just click the microphone icon and speak naturally—ChatRTX will process your voice and respond with accurate, AI-generated answers.
Private Image and Photo Search
Need to locate specific images or photos? ChatRTX enables text and voice-based photo search using AI models that understand your queries. Your content stays local, and your data stays private.
Powered by NVIDIA TensorRT-LLM and NIM
ChatRTX leverages TensorRT-LLM for highly optimized language model performance on RTX hardware. In addition, it supports NVIDIA NIM microservices—a suite of optimized inference microservices for deploying modern AI models with ease. With NIM, developers and power users can accelerate their workflows, build AI-powered tools, and make full use of their GPU-accelerated systems.
These technologies make ChatRTX not just a chatbot, but a flexible, local AI platform for personal and professional productivity.
