Chat with RTX by Nvidia

Chat with RTX is a downloadable AI application from Nvidia that installs and runs entirely on the user's local Windows PC using the compute resources of a compatible Nvidia RTX 30 or 40 series GPU. The application uses Retrieval Augmented Generation to index and query locally stored files including documents, PDFs, and text-based content, returning answers grounded in the actual file contents rather than general model knowledge. Users can upload files to a local context window, ask questions about specific documents, request summaries, and carry out multi-turn conversations — all without an internet connection or cloud data transmission. Chat with RTX is used by professionals handling sensitive documents who cannot use cloud-based AI tools due to data privacy or confidentiality requirements, researchers working with large local document libraries who want conversational access to their archives, and technology enthusiasts who want to run capable AI models locally on hardware they already own. A typical workflow involves launching the application, pointing it to a local folder of documents, and beginning a conversation with questions about the content of those files. Compare alternatives. The application is free to download and use for owners of compatible Nvidia RTX 30 or 40 series GPUs running Windows 10 or Windows 11. Chat with RTX offers a meaningful privacy advantage over cloud-based document AI tools since no data leaves the local machine, making it appropriate for use cases where document sensitivity or organizational data policies prohibit external AI processing. The primary access requirement is hardware — a compatible Nvidia RTX GPU with sufficient VRAM — meaning the tool is not available to users on systems with integrated graphics, non-Nvidia GPUs, or older GPU generations. Performance, response quality, and supported model options depend on the specific GPU model and its VRAM capacity Discover more tools.
