If you own an RTX GPU, you can now get a free AI chatbot that runs entirely on your PC. This tool uses your GPU’s power to run open-source language models like Llama or Mistral locally, so your data never leaves your computer.
Because it leverages TensorRT-LLM on the RTX GPU, responses come faster than what you’d get from CPU-only tools. The app can also index your local files, including PDFs, Word documents, text files, and transcripts, allowing you to ask questions about your own content privately. It’s a practical way to get a free AI chatbot with the security of a private AI assistant that operates as an on-device LLM.
System Requirements and Supported RTX GPUs
Before you start the Chat with rtx download, you need to ensure your PC has the right hardware. This AI tool runs entirely on your local machine, so your graphics card does all the heavy lifting. The minimum requirements are clear: you need an RTX GPU with at least 8 GB of VRAM, 16 GB of system RAM, and Windows 10 or 11. That is the baseline. If your system falls short, the software simply will not work.
Which RTX GPUs Are Compatible?
NVIDIA has not published an exhaustive list, but any RTX graphics card with 8 GB or more of VRAM should be a safe bet. That includes both desktop and laptop RTX GPUs. For example, an RTX 3060 with 12 GB VRAM works, as does an RTX 4060 with 8 GB. The RTX 30 and 40 series are the most common choices here. Older RTX 20 series cards with 8 GB (like the RTX 2080) may also work, but NVIDIA has focused compatibility on the newer generations. Laptop users can breathe easy: mobile RTX GPUs with sufficient VRAM are supported, though performance may be slightly lower than their desktop counterparts due to thermal and power limits.
How to Check If Your GPU Is Supported
Not sure if your card meets the VRAM requirements? Here is a quick way to check. Open the Task Manager (Ctrl+Shift+Esc), click the Performance tab, and select your GPU. Look for the Dedicated GPU memory entry. If it shows 8 GB or more, you are good to go. Also, ensure your system has 16 GB of RAM and that you are running a 64-bit version of Windows 10 or 11. If you meet these conditions, you can proceed with the Chat with rtx download and start using the tool immediately.
How to Download and Install NVIDIA Chat With RTX
Once you have confirmed your system meets the requirements, the next step is getting the software onto your machine. Chat With RTX is offered as a free download from the official NVIDIA website for supported RTX PCs. Head to the NVIDIA download portal and locate the Chat With RTX page — it is clearly marked and easy to find. Keep in mind that current builds are roughly 36 GB, so this is not a quick download over a slow connection. Make sure you have enough free space on your drive and a stable internet connection before you begin the chat with rtx download.
Step-by-Step Installation Guide
After the large download finishes, the process becomes straightforward. The file you receive is a standard Windows executable, so you just double-click it to launch the setup wizard. No unusual steps or command-line work is required here. The installer will guide you through the usual prompts — accept the license terms, choose an installation folder if you prefer, and wait for the files to copy. Given the size of the package, the setup wizard may take a while to complete, so be patient.
Once the installation finishes, the tool is ready to use immediately. One of the most practical aspects of this offline installation is that all processing happens locally on your RTX GPU. You do not need an internet connection for inference — everything runs entirely on your own hardware. That makes it a reliable choice for privacy-conscious users or anyone with intermittent connectivity. After the setup wizard finishes, you can launch the application from your Start menu or desktop shortcut and start interacting with the AI right away.
Supported File Formats and Indexing Capabilities
Once you have the app running, the next step is feeding it the documents you want to query. Chat With RTX indexes files stored directly on your PC, using a local RAG (Retrieval-Augmented Generation) pipeline. This means the AI searches through your selected folders to find relevant text, then generates answers without sending any data to the cloud. Understanding what file types the tool can handle helps you get the most out of it from the start.
The app supports a practical set of common formats. You can point it toward PDFs, Word documents, text files, and transcripts. This covers most everyday use cases, from research papers and project reports to personal notes. Because the indexing happens on your local machine, document indexing speed and capacity depend entirely on your hardware. There is no official limit on file size or the number of files you can load, but your available VRAM and system memory are the real constraints. If you have a large library of documents, expect longer initial indexing times, especially on systems with less RAM.
What Types of Transcripts Are Supported?
Transcripts are a notable inclusion, likely covering formats like.txt or.srt files often used for video transcripts and meeting notes. NVIDIA has not provided a detailed list of specific transcript formats, so you may need to experiment. In practice, saving your meeting notes or video captions as plain text files is a safe bet for compatibility. This feature makes the tool especially useful for reviewing recorded calls or online course materials without manually searching through hours of content. The local RAG pipeline keeps everything private, so sensitive transcripts from work meetings or personal journals never leave your PC.
Performance and Model Options
That privacy-first local processing extends to the core engine powering the experience. The Chat with RTX download includes TensorRT-LLM, a library that optimizes model execution specifically for your RTX GPU. Instead of relying on slower CPU-based inference, TensorRT-LLM accelerates calculations on the graphics card, making responses noticeably faster. This means you get near-instant answers to queries, whether you’re summarizing a document or searching through a local knowledge base.
Right now, the app supports two popular open-source model families: Llama 2 and Mistral 7B. Both are lightweight enough to run locally on consumer hardware, but they have different strengths. The exact selection available to you may vary depending on the build version you’re using, but in general you’ll have access to one or both.
Choosing Between Llama and Mistral
Llama 2, developed by Meta, is a versatile general-purpose model that handles a wide range of tasks—from creative writing to factual Q&A. Mistral 7B, on the other hand, is designed for efficiency and often performs well on reasoning and coding tasks while using fewer resources. If you’re working with technical documents or code snippets, Mistral might feel snappier; for broader conversational use, Llama 2 is a solid choice. You can switch between them easily within the app to see which one better fits your workflow.

Because all processing stays local, there’s no cloud dependency—your data never leaves your PC. The entire Chat with RTX download, including the app and the pre-loaded models, weighs in at around 36 GB. That’s a one-time download that gives you a powerful, private AI assistant running entirely on your own hardware. With GPU acceleration, you get the speed of a cloud service without the privacy trade-offs.
Chat With RTX vs. Alternatives: GPT4All, Ollama, and LM Studio
Chat With RTX is a strong choice if you own an NVIDIA RTX GPU, but it’s not the only local LLM tool out there. Depending on your hardware and workflow, you might prefer one of the other popular open-source chatbot tools. Here’s how they stack up.

If you have an older laptop or a system without an NVIDIA card, GPT4All lets you run local models on CPU alone. It’s a practical option for users who want privacy but don’t have dedicated graphics hardware.
Ollama takes a different approach. It provides a command-line and API workflow, making it ideal for developers who want to script model interactions or integrate local LLMs into other applications. You can pull models, run them from the terminal, and connect them to custom tools. It’s lightweight and efficient, but less beginner-friendly than a graphical app.
LM Studio offers a polished desktop interface similar to Chat With RTX. It includes a built-in chat window and an OpenAI-compatible local server, meaning you can point other apps at it as if it were a cloud API. It runs on multiple platforms and supports a wide range of open-source models, giving you flexibility without being locked to NVIDIA hardware.
When to Choose Chat With RTX Over Alternatives
If you already have a Windows PC with an RTX GPU, Chat With RTX is the most straightforward option for a chat with rtx download. Its tight integration with NVIDIA’s TensorRT-LLM gives you fast inference speeds right out of the box. You don’t need to fiddle with command lines or configure API endpoints. For a user who wants a private, GPU-accelerated assistant with minimal setup, Chat With RTX is the practical pick. For broader hardware support or developer workflows, GPT4All, Ollama, or LM Studio may suit you better.
