Private AI assistant that runs entirely on your device.
We are currently working on bringing Stelix to the App Store for iOS and macOS.

What is Stelix?
Stelix is an AI assistant that runs directly on your device. No internet, no data collection. Just you and Stelix AI.
Your conversations stay on your device by default. Private from the start, with you in control.
Responses appear instantly because everything runs on your device. No waiting for a server to respond.
Once you download Stelix, it works without any internet connection. Use it on planes, in tunnels, on trains, or off the grid.
Have conversations, ask questions, or brainstorm ideas. Stelix remembers the context and keeps things flowing naturally.
No setup, no technical knowledge. Stelix works like any app you already use. It handles updates and improvements automatically so you always have the best experience.
