AI that adapts to the human, not just the prompt.
Nefesh is the biometric context layer for AI.
The Problem
AI systems respond to text, not to the person behind it.
Large language models and conversational AI systems process syntax and semantics with remarkable sophistication. But they have zero access to the physiological state of the person interacting with them. The same words from a calm user and a distressed user produce identical responses.
The Engagement Layer
Real-time physiological awareness for AI systems.
Nefesh translates live biometric signals into structured state classifications — stress, calm, focus, acute distress — delivered via API. AI systems can adapt tone, pacing, escalation logic, and intervention timing based on the user’s actual physiological state.
The Impact
When AI understands physiology, users stay longer.
When AI adapts to physiology — not just text — sessions run longer, users return more frequently, and satisfaction increases measurably. Nefesh-powered systems create a fundamentally different interaction quality that users can feel.
