NeuralXP

NeuralXP is an open-source offline AI language model tool that runs a real LLM locally on old Windows XP-era machines with no cloud, no subscription, and no telemetry. It is aimed at people who want a private, local AI assistant on aging or low-spec hardware rather than a $2000 GPU or a monthly fee. NeuralXP is powered by the Qwen2.5-0.5B model via llama.cpp and ships as a native Windows application with a real .exe installer and a native Windows UI, avoiding Electron and the roughly 800MB Chromium overhead that comes with browser-based apps. Its hardware requirements are deliberately minimal: a minimum of 512MB RAM, a single-core CPU, no GPU, and Windows XP SP2 or later. Because inference runs entirely on the machine, prompts never leave the device, with zero network calls and zero telemetry. The project emphasizes longevity, with no forced updates and no deprecated APIs, and is fully open source under GPL v3 with every line published on GitHub so it can be audited, forked, and run on old hardware. NeuralXP is described as free forever. As a small, half-billion-parameter model running on very limited hardware, its capabilities are far more constrained than large cloud models, and it is a niche tool focused specifically on reviving abandoned Windows machines.

People with old or low-spec Windows machines use NeuralXP to run a private, offline AI language model locally without cloud, GPU, or subscription.
