Preply is using OpenAI's technology to create personalized lessons for language learners. The company has launched a feature that generates summaries of study materials and provides feedback on students' progress. This is done by combining AI-generated content with human tutors, who review and refine the results. --- Why it matters: This matters because it shows how AI can be used to augment human teaching, rather than replacing it. By automating routine tasks like summarizing study materials, human tutors can focus on more complex and high-value tasks. Source: https://openai.com/index/preply
