The Synheart Stack from signal to self-awareness.
Each product connects a layer of the emotional computing stack — sensing, inferring, analyzing, and reflecting emotion across research and real life. Together, they create the Synheart ecosystem: a complete platform for emotion-aware AI.

Synheart Core
Unified SDK for human-state intelligence — single integration point for all Synheart features
Synheart Core SDK is a modular, on-device human state intelligence system that collects multi-modal signals, fuses them into a unified state representation (HSV - Human State Vector), and provides optional interpretation modules for focus and emotion.

Wear Module
Collects biosignals from wearable devices.
Phone Module
Collects device-level signals.
Behavior Module
Captures interaction patterns.
Emotion Module
Estimates affective states from physiological and behavioral signals.
Synheart Focus
Real-Time Cognitive State Inference
Synheart Focus is a heart-driven framework that measures and enhances cognitive focus by linking real-time heart rhythm dynamics (HRV) with task performance, enabling physiologically grounded, adaptive focus assessment without relying on subjective reports.
Applications:
- Focus and attention scoring
- Bioadaptive cognitive training
- Stress–performance balance analysis
- Human–AI state awareness
- Research on heart–brain coherence
Core principles:
- Physiology-first focus modeling
- Continuous, real-time measurement
- HRV–behavior coupling
- Adaptive, feedback-driven design
- Privacy-preserving experimentation

Human-State Interface (HSI)
On-device models for Emotion, Focus, and Behavior.
Human State Interface (HSI) is a language-agnostic, contract-only specification for exchanging human-state signals between independent systems (producers and consumers).
Applications:
- Focus and distraction modeling
- Digital well-being analytics
- Behavior-aware AI agents
- Adaptive UI and system design
- Privacy-first behavioral research
Core principles:
- Contract-only
- Language-agnostic JSON
- Canonical schema
- Normalized scores + confidence
