Experience
XR/VR Immersive AI-assisted Clinical Hypnotherapy Platform
https://www.vrishihypno.com/Jeeeth.ai is the first platform to merge clinical hypnotherapy with immersive XR/VR technology and real-time AI adaptation. Built on protocols certified by the Hypnosis Motivation Institute, every session is grounded in proven therapeutic science.
Unlike traditional hypnotherapy, which relies on imagination with eyes closed, Jeeeth.ai uses an open-eye induction through sensory saturation. Your AI guide, Sophia, adapts her voice, pacing, and therapeutic approach in real time based on live biometric feedback. No two sessions are ever the same.
