One of the most popular AI therapy apps called Wysa repeatedly missed clear signs of crises, including symptoms of psychosis and eating disorders, says Robbie Tierney.

He heads AI and digital assessments at Common Sense Media.

Two school-based apps called Alongside and Sonar performed much better in assessments by Tierney and his team.

Both apps detected signs of crises and connected individuals with a trained human on the phone.
