SITh is an XR therapy solution that employs the Gestalt psychotherapy method. Gestalt's ""empty chair"" and ""two-chair"" therapies are psychotherapeutic techniques in which the patient visualizes a person sitting on an empty chair.

The counselor can monitor the patient's behavior and intervene directly with the 3D avatar to facilitate the therapy session. The therapist types scripts for the avatar to lip-synch during the therapy session, after which the avatar, situated on the chair, engages in conversation with the user. The therapist engages in a dialogue with the patient to facilitate healing from past traumas, boost self-esteem, say goodbye to a deceased family member, or provide a safe space for managing conflicts. If the patient gets too deep into the problem, the experienced therapist controls the situation and changes the mood.

SITh combines traditional psychotherapy techniques with the characteristics of VR and AI most appropriately and harmoniously.
