Darsel

Darsel is a nonprofit education technology platform that provides a text-based, personalized math learning chatbot designed for low-resource, low-connectivity settings. It reaches students via familiar messaging channels (SMS, WhatsApp, Facebook Messenger) and pairs with schools to deliver curriculum-aligned content and teacher analytics.

The product is a text-based, automated personalized learning chatbot that works over low-bandwidth channels. Students interact via messaging on platforms like WhatsApp, Facebook Messenger, or SMS, without apps or passwords. The system uses a learning algorithm to adapt to individual student levels, delivering hints, explanations, and a gamified experience. It offers a math library of over 500,000 questions aligned to local curricula, supports teacher customization of content, and provides data reports on student skills at both the individual and classroom level. When homework is assigned, the platform handles grading, and teachers receive ongoing support and analytics. Content is available in local languages where possible, and the system is designed to require minimal data and work without video buffering.
