The app features functions such as an emotional diary and structured courses on topics including managing anxiety and stress regulation. A personalized chatbot, powered by large language models (LLMs) and trained on content grounded in cognitive behavioral therapy, delivers evidence-based strategies such as cognitive restructuring, behavioral activation, and emotion regulation. The chatbot also guides users through these resources using natural, supportive conversations.~Participants were randomly assigned to one of two groups:~A treatment group offered free access to the app for three months, or A control group, which will receive free access to the app for one month at the end of the study"
