WALL STREET JOURNAL - SciMatch, a dating app launched in 2022, uses AI to analyze faces to deduce personality traits and suggest compatible matches, focusing on both similarities and differences in personality. Developed by sisters with degrees in data science and compute science Yanina and Viktoryia Strylets and inspired by research, it claims over 70% accuracy in predicting big five personality traits. However, some experts question its effectiveness, emphasizing that true compatibility requires face-to-face interaction. The app, with 5K active monthly users, offers free services with optional paid extras and has facilitated several successful matches, with users vouching for its accuracy.
