AI-powered school mental health chatbot

Alongside.care provides AI-powered mental health support for secondary school students via a 24/7 chatbot called the llama, backed by clinicians, to supplement school counselors. The chatbot uses evidence-based tools from CBT, ACT, and DBT in the student’s native language to help them cope and solve problems, escalating severe cases to counselors during school hours and offering resources after hours. It stands out by combining clinician-informed AI with multilingual, round-the-clock support that integrates into school systems and follows clear escalation pathways. The goal is to give immediate, accessible mental health support while expanding the capacity of school counselors to improve student well-being at schools.
