CortexOS
Read full descriptionHide full description
CortexOS is the journal that learns who you are. Write or speak. CortexOS listens, understands your emotions, and gives you something no other journal can. Everything runs on your device. No cloud. No data harvesting. No one reads your words. Ever. EU AI Act compliant. YOUR AI GETS SMARTER OVER TIME Most journaling apps treat every entry like the first. CortexOS builds a private Psyche layer: a living picture of your patterns, your people, and your growth. Now in its second generation, it ages like real memory: what keeps proving true grows stronger, what you've outgrown quietly fades. IT REMEMBERS WHAT MATTERS Mention something in a reflection and CortexOS can recall the moment you wrote about it months ago. Your journal becomes a memory that works for you. IT UNDERSTANDS THE MOMENT YOU'RE IN A job loss is not a bad mood. A new baby is not just "tired." CortexOS recognizes over 100 life situations and meets each one the way a thoughtful friend would: knowing what helps, and what never to say. IT LEARNS WHAT LIFTS YOU It notices what weighs on you and what reliably helps. Rate your sessions and it learns your taste. Your AI, shaped by you. PULSE Tap a mood, write a sentence, save. A 10-second check-in for busy days. Counts in every mood trend, never uses up your monthly free entries. VENT & BURN A space for the heavy stuff. Speak or type. Audio is securely wiped after transcription. When you're done, the entry burns. Nothing left, anywhere. DEEP ANALYSIS ON EVERY ENTRY After you write, an on-device LLM reads between the lines: emotional patterns, cognitive habits, growth you might not see yourself. Entries save instantly. BEHAVIORAL PATTERNS Rumination, self-compassion, stress responses, growth. Trend chips show what's emerging, fading, stable. Nothing diagnosed. Just named, so you can notice it yourself. SELF-AWARENESS CARD What CortexOS has learned about you: themes, tendencies, what weighs on you, what helps. Written entirely by the on-device AI. Visible only to you. AI REFLECTIONS Talk through what's on your mind by text or voice. The AI remembers your themes, replies faster than ever, and asks questions that take you deeper. Never judged, never uploaded. VOICE JOURNALING Speak instead of type. On-device transcription catches every word, even long, winding entries. No internet needed. INSIGHTS & PATTERNS Track 20+ emotions over time. Spot mood trends, triggers, and the connections between life events and how you feel. CHAPTERS Every week becomes a chapter in your story. Auto-titled, themed, and summarized by AI. MIND WRAPPED A shareable card deck at entry milestones and at year-end, every card stamped "0 bytes sent anywhere". YEAR IN REVIEW Your year, told from your own words: your emotional arc, your chapters, the growth you might have missed. Built on-device. SMART NOTIFICATIONS Prompts drawn from what you've been writing about. Like a quiet tap from someone who knows you. ENTRY ECHOES & GHOST TEXT Old entries resurface to remind you what you've already told yourself. A gentle prompt appears when the page sits empty. THERAPIST REPORTS A shareable PDF of your patterns and trends. No journal content included. Just what your therapist actually needs. PRIVATE BY DESIGN - AES-256-GCM encryption on every entry - Even the AI's memory is encrypted at rest - Zero-knowledge cloud backup (we can't read your data) - On-device AI. Nothing sent to servers. - Optional Deep Recall language pack: sharper memory, still 100% on your phone - Screen recording and mirroring blocked at the system level - No email, no password. Recovery phrase only. Face ID / Touch ID. - No tracking. No ads. No exceptions. Built by a solo developer in Malta, Europe. No investors, no data deals. A journal that is yours alone.

InnerLight

InnerLight helps you think more clearly about what’s actually going on in your life. It doesn’t try to give you answers. Instead, it helps you slow down and look at your thoughts from a different angle. People who are used to thinking a lot don’t always stop to examine how they’re thinking. It’s easy to rely on quick conclusions, even when they’re not quite right. InnerLight helps you pause and take a closer look. It helps you examine your own thinking, so you can understand what you’re feeling, question your assumptions, and make better decisions. --- ## What you can do with InnerLight • Start a conversation anytime, your personal AI mentor. Talk through something on your mind, whether it’s a decision, a situation, or a recurring thought. • Journal at your own pace. Use guided prompts or write freely to process things in your own way. • Revisit your thoughts. Your past entries and conversations are saved so you can reflect and notice patterns over time. • Track how you feel. Connect your thoughts with your emotional state and see how things evolve. --- ## Who it’s for • People who tend to overthink but still feel unsure about their decisions. • People who want clarity without being told what to do. • People trying to understand themselves better and make more intentional choices. • Anyone who feels stuck, conflicted, or mentally cluttered. --- ## What makes it different • Focus on thinking, not advice. InnerLight helps you examine your own reasoning instead of giving you conclusions. • Built around questions. The experience is designed to challenge your thinking, not replace it. • Designed for real use, not just inspiration -- something you can return to whenever you need to process something. • Stored locally on your device. Your conversations and reflections stay with you, not on external servers. --- ## Not therapy InnerLight is a thinking companion, not a medical or mental health service. It does not provide diagnosis, treatment, or crisis support. # About InnerLight Full InnerLight full is a subscription that allows you to fully use the app. * Subscription Terms: Payment will be charged to your Apple ID account at confirmation of purchase.
