We believe Rori can more than double math learning for students that access the chatbot multiple times a week. We want to reach 2m+ students by 2027, and 5m+ students by 2030.

About the innovation

Why did you create this innovation?

200 million children in Africa aren’t achieving minimum levels of proficiency in mathematics.

Research shows that high-quality, high-dosage tutoring is one of the best ways to improve outcomes.

Despite the growing size of the private tutoring market, access to the high-quality provision is out of reach for the vast majority of children. Rori addresses that gap.

How does your innovation work in practice?

Rori is a virtual math tutor built for low-resource settings. Students converse with Rori on their phone, for free, in natural language via WhatsApp.

Rori delivers micro-lessons, asks practice questions and understands students’ answers. Students progress through topics at their own pace.

Conversational format creates a durable, friendly rapport between the bot and the student and promotes meta-cognition.

We are also currently integrating text-to-speech technology that will make the Rori more accessible to children with low-levels of literacy.

How has it been spreading?

Since being launched to the public in November 2022, Rori has reached over 40,000 users across multiple countries for a customer aquisition costs of less than $0.10c per user.

Rori was developed across 30 schools in Ghana, with a large, representative sample of the types of teachers, parents and students who will be using Rori. This has allowed us to follow best practices in human centered design and conduct rapid micro-evaluations as we developed the products capabilities.
