CortexOS v1.2 — The Psyche Layer: Your Journal Now Understands Who's Writing It

Ten days ago we launched CortexOS as the first Zero-Knowledge AI Journal. A full LLM on your phone. Every entry encrypted with keys only you hold. Nobody can read your data. Including us.

That was the foundation. Here's what we've shipped since.

Deep Analysis (v1.1.0) Every entry now gets a real interpretation from the on-device LLM. Not a sentiment label. The AI reads what you wrote and reflects back what's underneath. Emotions you didn't name. Patterns forming. Connections to entries from days or weeks ago. Runs silently after save.

The Psyche Layer - Adaptive Intelligence (v1.2.0) Before this, CortexOS understood each entry on its own. Now it connects the dots across your full history.

The Psyche Layer is a persistent, encrypted psychological profile on your device. Your recurring themes, emotional tendencies, cognitive patterns, unresolved threads. Every feature draws from it. Reflections get sharper. Deep Analysis connects today to three weeks ago. Nudges become yours.

The Self-Awareness card in Insights gives you a window into your own Psyche Layer.

Always-On Intelligence (v1.2.1) The Psyche Layer now updates in real time with every entry. Prompts and reminders reference your actual themes instead of generic suggestions.

Everything still runs on your phone. Zero-knowledge architecture unchanged. The developer cannot access your data.

The app that launched ten days ago analyzed your entries. The app today understands who's writing them.

Free tier available. 14-day Premium trial. No card needed.
