A University of Waterloo student has developed an AI-powered app, Doro, designed to support individuals showing early signs of mental health conditions. Doro, described as a "daily mental health coach," offers 30-minute chat sessions to help users manage feelings such as stress and anxiety. The app uses cognitive and behavioral techniques from therapy, like mindfulness and grounding exercises, to provide immediate support. Co-creator Rastin Rassoli explains that Doro is designed for those in the subclinical stage, where mental health symptoms may not require diagnosis but still affect well-being.

Developed with a blend of computer science and psychology, Doro employs specialized large language models trained on therapy methods and has undergone clinical trials with positive results. Rassoli emphasizes that Doro supplements, not replaces, therapy by helping users manage residual symptoms post-therapy and referring them to professionals if severe symptoms arise.

Recently launched at Waterloo’s Campus Wellness and mental health clinics in Ontario and Alberta, Doro is supported by Dr. Goldi Gill, who highlights its value as a self-help tool for students needing lifestyle guidance. Currently available on Doro’s website, plans for app store availability are underway. The project is backed by Waterloo’s Enterprise Co-op program and the Velocity incubator, with support in market understanding and customer needs.
