What it does

Every AI journal sends your thoughts to a server. CortexOS doesn't. A full LLM (Llama 3.2) runs entirely on your phone. Voice transcription, 20+ emotions, 15 distortions, AI reflections, emotional chapters, yearly review. All on-device. All encrypted. Offline or online. Your entries are locked behind a 6-word phrase and PIN only you know. We can't read your data. Nobody can. That's not a setting. That's the architecture. New category: Zero-Knowledge AI Journal. Solo-built. 14-day free trial.
