Physiological truth for mental health systems.
API middleware that replaces self-report with real-time physiological signals for mental health platforms.
The Problem
Mental health tools rely on self-report in moments of highest distortion.
Digital mental health platforms ask users to describe their physiological state precisely when that state is most likely to distort self-perception. Stress, anxiety, and acute episodes systematically undermine the accuracy of self-reported data.
Signal Detection
Replacing self-report with real-time physiological signals.
Nefesh delivers continuous, real-time physiological state data — derived from heart rate variability, stress scoring — to mental health platforms. Responses can be timed and adapted based on what the body signals, not what the user reports.
The Signal
What people say vs. what bodies show.
Self-report accuracy collapses exactly when it matters most. Nefesh reads the body instead.
"I'm doing okay, just a bit tired."
Classified: Moderate — no intervention triggered.
