 Project N.O.M.A.D. (Node for Offline Media, Archives, and Data; "Nomad" for short) is a project started in 2025 by Chris Sherwood of [Crosstalk Solutions, LLC](https://crosstalksolutions.com). The goal of the project is not to create just another utility for storing offline resources, but rather to allow users to run their own ultimate "survival computer".
 
-While many similar offline survival computers are designed to be run on bare-minimum, lightweight hardware, Project N.O.M.A.D. is quite the opposite. To install and run the available AI tools, we highly encourage the use of a beefy, GPU-backed device to make the most of your install.

See the [Hardware Guide](https://www.projectnomad.us/hardware) for detailed build recommendations at three price points.
 
 Since its initial release, NOMAD has grown to include built-in AI chat with a Knowledge Base for document-aware responses, a System Benchmark with a community leaderboard, curated content collections with tiered options, and an Easy Setup Wizard to get new users up and running quickly.
