Kairos is a voice AI company developing models that interpret patterns in a person’s voice to help them understand their mental state and learn when and how to recover. Its approach focuses on how people shift through everyday moments, using voice as a window into changes in mind, body, and emotional presence. Kairos describes these experiences through paired dimensions: clarity and processing speed, which relate to how easily and quickly thoughts come together; tension and arousal, which reflect bodily tightness and activation; and valence and expressiveness, which capture emotional tone and how vividly it is conveyed.

Together, these measures are intended to describe whether thinking feels clear or effortful, the body relaxed or restless, and emotional expression lively or subdued. Kairos invites people to join its early access list and provides information about the company, privacy, and terms of service. The company identifies itself as Kairos OS, Inc.

Its stated purpose is to make patterns in voice useful for understanding personal wellbeing and supporting mental recovery
