Tinker Bot is a chatbot that helps users learn through conversations on Facebook Messenger without needing to download an app. It uses natural language processing and personalized learning to improve the education experience. Revenue comes from subscription plans for tutors, schools, and colleges starting at $12-30 per month. The founders aim to market it through educational institution seminars and social media. While other education apps have large user bases or high production value, Tinker Bot aims to provide affordable personalized learning through a familiar platform.
