In plain English
An avatar-based therapy assistant built on Acceptance and Commitment Therapy principles that analyzes facts, emotions and safety in real time and logs results for supervising clinicians. In text-only comparisons, 11 psychotherapists rated GPT-5.2 responses above human therapist responses; the authors stress this covers verbal content only and is not a replacement for clinicians.
