From Video to Evaluation: Automating Quiz Creation and Grading with Generative AI

Our client, a global video management platform serving educational institutions, sought to enhance engagement and reduce manual workload in their learning content. We designed and implemented an end-to-end solution that converts passive lecture videos into interactive modules—automatically generating quizzes and grading open-ended responses using advanced LLMs. This transformed their platform into a scalable, intelligent assessment engine, driving higher engagement and significantly reducing instructor workload.
