I bought an AI PC and the NPU did nothing. Windows ignores it. No consumer app uses it. So I built NPUse — it detects your NPU, installs optimized AI models, and runs ChatGPT-quality chat on-device. No cloud, no API keys, no monthly fees. 🔍 NPU detection + model installer 💬 Local chat — no internet needed 📄 Document analysis — fully private Free tier available. $29 one-time for full version. Python + llama-cpp + HuggingFace + ONNX Runtime.
