How Lumenta's AI Works

CBT-Informed Approach

Lumenta's on-device AI is designed around principles from Cognitive Behavioral Therapy (CBT)—a well-researched, evidence-based approach used by mental health professionals worldwide.

When you share your thoughts with Lumenta, the on-device AI gently helps you:

• Lumenta interprets your sentiment (e.g., "I'm feeling overwhelmed") to offer targeted coping strategies.
• Over time, Lumenta identifies patterns in your cognitive distortions (like catastrophizing or black-and-white thinking).
• Automatic reminders to prioritize wellness activities that have historically improved your mood.
• A comprehensive overview of your wellness journey, powered by secure, local data analysis.

Holistic Data Integration

What makes Lumenta different from generic AI chatbots is its holistic awareness of your wellness journey. Lumenta's responses aren't generic—they're tailored to you.

When you chat with Lumenta, the AI considers:

• Recent mood entries — How you've been feeling lately
• Journal notes — What's been on your mind
• Voice recordings — Transcribed thoughts and feelings
• HealthKit data — Sleep quality, step count, and activity levels

This means if you mention feeling tired, and Lumenta knows you only slept 4 hours last night, the response will acknowledge that connection—making the conversation more relevant and helpful.

Sentiment-First Architecture

Lumenta doesn't just process words—it understands emotional energy. Using a Sentiment-First Architecture, Lumenta performs an internal check before every response:

• Energy Matching — Adjusts its tone and pace to match yours, from quiet validation to gentle encouragement.
• Immediate Pivoting — If you express distress or a "block" during an exercise, Lumenta stops immediately to prioritize your feelings.
• Zero Toxic Positivity — Lumenta is logically forbidden from giving cheerful or generic praise when you're hurting or feeling resistant.
• Unconditional Acceptance — If you're feeling nihilistic or stuck, Lumenta sits with you in that space without pressure to "fix" it.

All of this happens entirely on your device. The goal is a companion that feels truly synced with your emotional state, providing support that is relevant, respectful, and safe.

AI-Powered Health Insights

Beyond chat, Lumenta's AI analyzes your check-in history and HealthKit data to surface meaningful patterns you might not notice on your own.

• Check-in Analysis — AI reviews your saved mood entries, journal notes, and voice recordings to identify trends over time
• HealthKit Correlations — Discovers connections between your physical data (sleep, steps, activity) and emotional wellbeing
• Personalized Insights — Surfaces patterns like "Your mood dips on Wednesdays—could midweek stress be a factor?"
• Pattern Recognition — Spots recurring themes in your journal entries and moods

All of this analysis happens on your device—your health data never leaves your iPhone.

100% On-Device with Apple Intelligence

All of this happens entirely on your device. Lumenta uses Apple Intelligence (Apple's on-device AI framework) to process your data locally.

• Your chats never leave your iPhone
• No data is sent to external servers
• No account or login required
• You can export or delete your data anytime

This is fundamentally different from cloud-based AI assistants. With Lumenta, your most personal thoughts stay exactly where they belong—with you.
