Half the world lacks access to essential health services. The barrier to good outcomes is often not only treatment — it's knowing when to seek care.
AI-powered triage tools delivered via WhatsApp could help change that. The AI Access Initiative (2AI), incubated at Evidence Action, has published a deep-dive on the evidence, the uncertainties, and where strategic philanthropy can make the biggest difference.
2AI grew out of work incubated at Evidence Action to evaluate how AI could deliver step-change impact for people in low- and middle-income countries. That work began with a cross-sector analysis, published in October 2025, evaluating 30+ AI interventions across agriculture, health, education, and humanitarian response.
The new opportunity analysis takes a deeper look at one of the priority areas that work surfaced.
