CortexOS is the journal that learns who you are.
Write or speak. CortexOS listens, understands your emotions, and gives you back something no other journal can. Everything runs on your device. No cloud. No data harvesting. No one reading 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 understanding of your patterns and growth. Every reflection gets more personal the longer you journal. We call it Adaptive Intelligence.
DEEP ANALYSIS ON EVERY ENTRY
After you write, an on-device LLM reads between the lines. It surfaces emotional patterns, cognitive habits, and growth you might not see yourself. Entries save instantly. The AI does its work quietly in the background.
BEHAVIORAL PATTERNS
CortexOS tracks the cognitive patterns and emotional rhythms in your writing over time. Things like rumination, self-compassion, stress responses, growth moments. Trend chips show you what's emerging, what's fading, what's stable. Nothing gets labeled or diagnosed. Just named, so you can notice them yourself.
SELF-AWARENESS CARD
What CortexOS has learned about you. Themes, tendencies, cognitive habits, growth moments. Built from your own words. Visible only to you.
AI REFLECTIONS
Talk through what's on your mind by text or voice. The AI remembers your themes, knows your patterns, and asks questions that help you go deeper. Without judgment, without your words ever leaving your phone.
VOICE JOURNALING
Speak instead of type. WhisperKit transcribes your voice entirely on-device. No internet needed.
INSIGHTS & PATTERNS
Track 20+ emotions over days, weeks, and months. See mood trends, spot triggers, and find the connections between life events and how you feel. CortexOS surfaces the patterns. You decide what to do with them.
CHAPTERS
Every week becomes a chapter in your story. Auto-titled, themed, and summarized by AI from your entries.
YEAR IN REVIEW
Once a year, CortexOS turns your entries into a full story of the year you lived. Your emotional arc month by month, your chapters, your themes, the growth you might not have noticed in the moment. Built from your own words, written on-device.
SMART NOTIFICATIONS
Your reflection prompts and reminders aren't generic. They pull from what you've actually been writing about and the patterns CortexOS has noticed. Nudges that feel like a quiet tap from someone who knows you.
ENTRY ECHOES & GHOST TEXT
Old entries bubble up to remind you what you've already told yourself. A gentle prompt fades in when the page sits empty. Small touches that make journaling a habit instead of a chore.
THERAPIST REPORTS
Generate a shareable PDF of your emotional patterns and cognitive trends. No journal content included. Just the insights your therapist actually needs.
