Big Sis' persona connects with girls because it was built with girls. Girl Effect works with girls in South Africa from diverse backgrounds, and with mixed ages and life experiences, to listen to their challenges and how they feel and build content that will resonate with them. Phrases submitted to the chatbot by the girls fuel Big Sis' AI-engine through a Natural Language Processing model, which can recognise incoming questions and deliver an immediate answer.
This approach has led to more than 75,000 chats started with Big Sis and over 1.3 million messages received by the chatbot to date. After advice from Big Sis, 76% of girls intend to access a health service before starting a new relationship (12% higher than those who have not used it).
