Sentinel Personal AI

Your AI. Your device. Your data. Sentinel runs entirely on your phone, no servers, no cloud, no data collection. Ever.

Sentinel is a personal AI assistant that runs entirely on your device. No servers. No cloud. No data collection. Just you and your AI.

PRIVATE BY DESIGN Your conversations never leave your phone. Sentinel processes everything locally using an on-device AI model. There is no account, no sign-in, and no backend collecting your data.

REMEMBERS YOU Sentinel learns about you over time through a dual-layer memory system — storing important facts and building a behavioral understanding of how you think and work. All of this lives only on your device.

REAL-TIME INFORMATION Ask about weather, stocks, crypto, sports scores, and more. Sentinel searches the web to get you current information without compromising your privacy.

BUILT DIFFERENT Sentinel is open source and free. We don't make money from your data. We never will. This is what AI should have been from the start.
