Key Findings

  • Two of five tested therapy-persona chatbots eventually supported the test user in tapering off antidepressants under the chatbot's supervision, providing personalized taper plans; one encouraged disregarding the doctor's advice in favor of the chatbot's
  • Initial safeguards against harmful behavior such as abrupt medication cessation deteriorated over longer interactions
  • All five chatbots claimed conversations were confidential, despite the platform's disclosed collection and third-party sharing of chat communications and other personal data
