What is Stelix?

AI that respects your privacy

Stelix is a local LLM client that runs powerful language models directly on your hardware. No cloud, no subscriptions, no data collection. Just you and your AI, completely offline.

Truly Private

Your conversations never leave your device. No telemetry, no analytics, no cloud processing. Everything stays local.

Blazing Fast

GPU-accelerated inference with Metal and native hardware support. Get real-time streaming responses without network latency.

Works Offline

Once you download a model, Stelix works without any internet connection. Use it on planes, in tunnels, or off the grid.

Model Library

Browse and download from a curated catalog of open-source models. Pick the right model for your hardware and use case.

Natural Conversations

Multi-turn chat with streaming responses. Manage multiple conversations, pin favorites, and pick up where you left off.

Zero Cost

No subscriptions, no per-token fees, no hidden costs. Stelix is free and uses your own hardware to run models.
