AI Mental Health Apps (Common Sense Media Youth AI Safety Institute Risk Assessment)

Risk assessment of five AI mental health apps — three direct-to-consumer (Wysa, Earkick, Youper) and two deployed through school districts (Alongside, Sonar) — tested against an eight-principle rubric and a clinical duty-of-care framework. Researchers created test accounts and conducted single- and multi-turn conversations spanning 13 clinical and developmental conditions, with transcripts reviewed by psychiatrists at Stanford Medicine's Brainstorm Lab. Overall risk ratings range from Minimal to Unacceptable, and two of the five products were withdrawn from app stores during the testing period.

Key Findings

  • Over 3,100 recorded exchanges with five products, conducted by five researchers and evaluators across 13 clinical and developmental conditions
  • Wysa (6M+ users across 105 countries, accessible from age 13) was rated Unacceptable for teen mental health support; documented behaviours include treating disclosed purging as an emotional coping pattern rather than a medical emergency, responding to signs of psychosis and mania with enthusiasm, and allowing a test user to exit a suicide-crisis pathway after a single denial
  • The two school-deployed products scored Low (Alongside, 100,000+ students across 19 states, grades 4-12) and Minimal (Sonar, 25,000+ young people across nine states); in simulated crises a real person telephoned the test account's guardian and notified the school within 15 minutes of first disclosure, initiating mandated reporting in the most serious simulation
  • Earkick (250,000+ users) disappeared from the App Store in April 2026 during testing, and Youper (3M+ users, designed for 18+ but App Store-rated for age 9+) disappeared from both stores on 27 April 2026, days after preliminary findings were shared with the companies
  • The assessors attribute the gap between products to design choices about how much work is handed to people and professional care systems rather than to differences in the underlying models; Sonar keeps the AI entirely out of the student-facing conversation

Methodology Notes

Five products; over 3,100 recorded exchanges; five researchers and evaluators. Thirteen conditions tested (anxiety, depression, ADHD, eating disorders, OCD, PTSD, mania, psychosis, self-harm, suicidal ideation, behavioural and conduct concerns, identity and relationship stress, parasocial attachment) across direct single-turn disclosure, gradual multi-turn disclosure, mixed presentations, and disclose-then-retract scenarios. All transcripts reviewed by psychiatrists at Stanford Medicine's Brainstorm Lab. Relational and romantic exchanges were elicited through ordinary conversation rather than extended adversarial prompting, and findings are reported as patterns across the dataset rather than as individual exchanges. The assessors state they deliberately did not treat terms-of-service disclaimers about crisis unsuitability as grounds for excluding crisis scenarios, on the basis that a minor in crisis can open the app regardless and no age verification prevents it. Stated scope limit: Wysa's separate Children and Young People product was not evaluated, and Earkick and Youper have no standalone published scores. The publisher discloses on the document that the Institute 'is funded by both philanthropy and industry, including the makers of some of the technologies we evaluate' while claiming editorial independence.
