How Preply combines AI and human tutors to personalize learning

# How Preply Combines AI and Human Tutors to Personalize Learning TL;DR: Preply uses AI as a co-pilot, combining it with the motivational power of human tutors. Through its "Lesson Insights" feature, it automates repetitive tasks, saving tutors more than half their lesson preparation time and significantly boosting long-term learner retention. ## Not Replacing Humans, but Empowering Them As stated in the video: "It's not about replacing humans, but giving them new abilities, sometimes even redefining the nature of work. For Preply, this is a tremendous opportunity to combine what we humans do best — motivation, interaction, and energy in the classroom — with AI components that act as a co-pilot." Preply is the world's largest language learning marketplace, with 100,000 tutors teaching over 90 languages across 180 countries. Humans have an incredible ability to motivate other humans, and teachers excel at this: "They inspire students to attend class, to complete their homework, and essentially maintain the energy in the classroom that is hard to replicate." ## The Pain Point of Repetitive Tasks At the same time, there are many repetitive tasks that tutors don't want to do and learners don't value highly. Examples include creating personalized plans, typing out detailed plans, taking notes, and preparing lessons. These tasks consume a lot of tutor time without directly improving learning outcomes. ## Lesson Insights: From Generic to Highly Targeted Preply developed the "Lesson Insights" feature. "It's essentially a personalized summary that you receive at the end of the lesson. It provides a recap of what was discussed, feedback on what went well and what can be improved, and suggestions on how to keep improving. It's shown to both the learner and the tutor." This feature shifts teaching "from a generic practice to something highly targeted, truly helping learners achieve what matters most to them at that specific point in time." ## Why OpenAI Preply chose to partner with OpenAI for several reasons. First, accuracy. "We provide feedback on your language, grammar errors, and how you speak. So the accuracy of language output is critical for us. We compared several different models and evaluated them against our framework. OpenAI performed exceptionally well on this front." ## A Tutor's Real Experience One tutor shared: "Lesson Insights helps me personalize lessons for my students by showing me where they need to improve. Before I started using Preply's AI features, I would spend many, many hours preparing lessons and assignments. Now, that time has been cut by more than half." ## Adoption Rates and Retention Data "For the Lesson Insights feature, we have over 70% of tutors opting in to use it, and 75% of learners opting in. So adoption is very high in terms of people wanting to use these features. We also see high per-lesson engagement." But the most critical signal is long-term retention: "We see that after more than a year, 70% of active learners continue to use Lesson Insights." ## AI Empowers Engineers to Focus More on Customers The video also highlights the role of the Codex model: "With a powerful tool like Codex, engineers can focus more on the customer. They don't have to spend as much mental energy remembering syntax, fixing errors, or correcting typos. They focus on the overall architecture of the system and solving customer problems with code. As a partner, OpenAI is able to teach us how to use their product in the most efficient way. And who better to teach you than the organization that created the world's best large language model?" ## Summary Preply unleashes the potential of human tutors by using AI as a co-pilot, while dramatically boosting efficiency through automation. The widespread adoption and long-term retention data for Lesson Insights prove that this combination is not only viable but effective. **Source:** How Preply combines AI and human tutors to personalize learning – OpenAI YouTube (https://www.youtube.com/watch?v=-Jm-Bf3g9r8)
