Argentina has one of the highest rates of psychotherapy utilisation in the world — Buenos Aires alone is said to have more psychoanalysts per capita than any other city on Earth. It also has a mental health crisis driven by economic instability, inflation, and the long aftermath of pandemic isolation. The problem was not cultural acceptance of mental health treatment. The problem was access and cost.

MenteSana, developed by the Ministry of Health in partnership with the University of Buenos Aires and technology firm Mercado Libre's social impact division, launched in November 2023 as a freely downloadable application available to any Argentine resident with a national identity number. The platform offers three tiers of support: AI-guided cognitive behavioural therapy modules for mild to moderate anxiety and depression; scheduled video sessions with licensed psychologists employed by the Ministry at no cost to the user; and a 24-hour crisis line with trained counsellors.

Within 14 months, 4.1 million unique users had registered — approximately 8.7 percent of the adult population. Usage patterns show the AI self-guided modules are most popular among users aged 18 to 34, while the live therapist sessions are disproportionately used by users over 45 who had previously accessed no mental health support.

Independent evaluation by the Pan American Health Organization found that 68 percent of users completing a full CBT module course showed clinically significant improvement on standardised depression and anxiety scales. Therapist session wait times, initially 12 days, have been cut to 4 days following a Ministry recruitment drive that added 800 contracted psychologists to the platform in mid-2024.

"In Argentina, the couch was always for the rich," said Health Minister Mario Russo. "We put it in everyone's pocket."
