Challenge
High-risk pregnancy poses a constant challenge for healthcare professionals: detecting warning signs before they evolve into serious situations, such as preeclampsia. At Santa Joana Maternity Hospital, this reality was even more complex due to team overload and limited immediate communication channels. Pregnant women—often with questions that arise outside service hours—needed an alternative that not only responded quickly, but also offered support and safe guidance.
Solution
To meet this demand, StaryaAI, together with Santa Joana Maternity Hospital, created “Madrinha Joana”: an intelligent and empathetic AI agent operating through WhatsApp Business. Through a co-creation process, the following were built:
