Multiple education technology organizations showcase their use of LLMs and LangChain to enhance learning experiences. Podzy develops a spaced repetition system with LLM-powered question generation and tutoring capabilities. The Learning Agency Lab creates datasets and competitions to develop LLM solutions for educational problems like automated writing evaluation. Vanderbilt's LEER Lab builds intelligent textbooks using LLMs for content summarization and question generation. All cases demonstrate the integration of LLMs with existing educational tools while addressing challenges of accuracy, personalization, and fairness.
