What's New in CortexOS

1.7.0

August 17, 2026

Your AI grew up. This is the biggest update we've ever shipped, and almost all of it happened inside your AI's head. IT REMEMBERS NOW. Bring something up in a reflection and CortexOS can connect it to what you wrote weeks or months ago, gently, like a friend who was actually listening. Your past entries stop being archive and start being memory. IT UNDERSTANDS WHAT'S HAPPENING TO YOU. A breakup, a layoff, a health scare, a new baby, a fresh city. CortexOS now recognizes over 100 life situations and responds with the care each one deserves: what to ask, what helps, and just as importantly, what not to say. THE PSYCHE LAYER, GENERATION TWO. The private picture CortexOS keeps of your patterns now ages like real memory: what keeps proving true grows stronger, what you've outgrown quietly fades. It also learned two things it never knew before: what tends to weigh on you, and what reliably lifts you. IT LEARNS FROM YOU. Rate your reflection sessions with a thumbs up or down and your AI takes notes. It learns how you like conversations opened and what a good summary sounds like in your life. Every week it fits you a little better. IT GOT FASTER. Reflection replies now come noticeably quicker, especially mid-conversation. Less waiting, more talking. VOICE JOURNALING CAPTURES EVERYTHING. Long, winding voice entry with pauses while you gather your thoughts? Every word lands now, start to finish. NEW: DEEP RECALL. An optional switch in Settings that gives your AI's memory a sharper engine, powered by a language pack that downloads once and never phones home. YOUR JOURNAL CAN MOVE WITH YOU. We laid the encrypted groundwork for carrying your journal across devices with nothing but your recovery phrase. Zero-knowledge, end to end: we couldn't peek even if we wanted to. AND THE POLISH: summaries that speak directly to you, sessions that always show what the AI noticed, waiting screens that appear the instant you need them, milestone celebrations that feel like milestones, and a long list of small fixes you'll feel more than see. All of it on your device. None of it in a cloud. That part never changes. Your Mind, Encrypted.
