RigorAI is a platform designed to help students develop modern rigor skills: adaptability, critical thinking, problem-solving, and resilience. Leveraging AI, the platform provides personalized learning pathways, adaptive challenges, and real-world simulations that move beyond rote memorization. Students engage with open-ended problems, receive feedback on their reasoning process, and track their progress in developing these transferable capacities. Teachers can use RigorAI to supplement their curriculum, design project-based learning, and assess students’ application of knowledge in dynamic contexts.
