# Apollo
Clinical
Apollo is thymia's clinical assessment model. From just 15 seconds of
natural speech, Apollo analyses **neural morphemes™** to produce
clinical-grade assessments of major depression and generalised anxiety
— including disorder-level probabilities, granular symptom scores
across all core DSM-V criteria, and a downloadable clinical report.
Designed for use by healthcare professionals, Apollo supports remote
and rapid mental health triage, enabling precise individual symptom
quantification, objective efficacy measurement, and enhanced patient
stratification — without requiring an in-person assessment.
Apollo is a regulated medical device. It is intended for use by
qualified healthcare professionals only and must not be used as
a substitute for clinical judgement. Apollo is not intended for
self-assessment or consumer use.
For non-clinical wellness monitoring, see
[Helios](/helios/overview).
