QuickTA is a LLM-based tool to support students in classroom or self-directed learning. In contrast to many emerging tools, relying solely on LLM mechanisms for finding knowledge and ensuring retrieval, QuickTA brings together high quality educational content, Reinforcement Learning adaptive algorithms and Intelligent Tutoring Systems to ensure that each student gets just-in-time support on the level they need: from hint to reflection prompt, from activating connection to previous knowledge to motivational support. In this project, TutorGen Inc works on bringing University of Toronto research behind QuickTA and Carnegie Mellon University expertise in AI systems for education to thousands of learners on Open Learning Initiative and other platforms.
