Joi App

Joi App – Emotion and Behavioral Prognosis AI Infused Management

Developed by a board-certified psychiatrist and a very dedicated team, Joi introduces the first patented multimodal AI assessment.

By analyzing facial expressions, voice patterns, and context together. Joi identifies emotional, stress, and depressive signals that traditional questionnaires alone cannot capture.

Experience a deeper and more precise understanding of your emotion and stress tolerance state — you’ll immediately see why this patented technology stands apart.

Joi currently supports Korean and English so users can easily choose their preferred language. Through a segmented three assessment system, including the machine learning multi-modal assessment, PHQ9 & GAD7 assessments, Joi App collects more accurate and reliable data, and uses AI-based in-depth analysis to evaluate the current states from multiple perspectives in real-time as it happens.

Log your mood and stress level now, and revisit how it changes after time. How quickly the recovery happens after an episode. How often these happen during a period. After each assessment, it can automatically generate an export ready PDF results report with personalized feedback that can be referenced during consultations at medical institutions.
