Turn your PC into a private AI server. Personal AI Server lets you run any GGUF language model locally and serve it as an OpenAI-compatible API. Pick a model file, press Start, and your PC becomes an AI endpoint that any app, script, or tool can connect to. Everything runs on your hardware — nothing is sent to the cloud. HOW IT WORKS Choose any GGUF model file on your PC, configure the port and context size, and press Start. The built-in llama.cpp engine loads the model and exposes an OpenAI-compatible chat completions API at the address shown. Any tool that speaks the OpenAI protocol — ChatGPT clients, coding assistants, Python scripts — can connect instantly. VISION SUPPORT Add an optional mmproj vision file and the server gains image understanding. Send photos alongside text prompts and get AI responses that describe, analyze, or reason about what's in the picture. GPU ACCELERATION Set GPU layers to offload model computation to your graphics card. More layers on the GPU means faster responses. Works with NVIDIA, AMD, and Intel GPUs. NETWORK ACCESS By default the server listens on localhost only — completely private. Toggle "Allow other devices on my network" to serve phones, tablets, and other PCs on your local network. WHO IT'S FOR Developers integrating AI into apps without paying per-token API fees. Privacy-focused users who want AI without cloud accounts. Enthusiasts experimenting with open-source models. Anyone who wants a local ChatGPT alternative. PRIVATE BY DESIGN 100% offline after install. Your prompts, your data, your model — none of it leaves your PC. No account, no subscription, no telemetry.
