The only way to make AI understand all of it is to upload everything to the cloud -- privacy nightmare, and way too expensive at scale. And it shouldn't be possible on-device either: small models are too dumb, and phones are too slow for thousands of LLM inference runs.So I spent a year deeply optimizing every layer of the on-device inference stack to make it possible anyway.Sentient OS runs a custom multimodal vision LLM on your phone and laptop while they charge overnight. It understands your entire digital life -- every screenshot, note, file, email, bookmark, plus integrations for external services -- with nothing ever leaving your device.This gives you three things that weren't possible before:-> Talk ...
