Sentinel

Your AI. Your phone. Nobody else's data. Every other AI app ships your words to a server. Sentinel doesn't. The language model runs on your phone. The speech recogniser runs on your phone. The voice that answers you back, the image generator that paints what you describe, the vision pipeline that reads your photos - all on your phone. Every chat, every voice clip, every generated image, every page of every PDF you've asked about - sealed inside a post-quantum encrypted Sanctum that nobody but you can open. Not us. Not Google. Not the next breach. Open the app on the train. Ask a real local LLM what to write to your lawyer. Snap a photo of a foreign menu and have it described back. Drop a 200-page PDF into your vault and ask one question. Speak it - Whisper transcribes - and hear the answer back in your language. Nothing on a server. Nothing in a log. Nothing in your 'AI history' page.
