Preply, the marketplace that connects more than 100,000 tutors with learners in over 180 countries across more than 90 languages, has rolled out an AI-powered feature called Lesson Insights built with OpenAI APIs. The tool analyzes lesson transcripts and produces structured, personalized reports for tutors and students within minutes.
How Lesson Insights works
With learner consent, one-to-one sessions in the Preply Classroom are recorded and transcribed. OpenAI models analyze those transcripts to generate feedback on grammar, vocabulary and pronunciation, along with a summary of key topics and recommended next steps. Those outputs feed Preply’s self-learning exercise engine to produce personalized homework and practice tailored to each learner.
Emily Stott, Staff Product Manager at Preply, said the feature gives students a clearer view of progress by converting lesson content, goals and tutor feedback into targeted practice. The company reports that about 75% of English-language learners actively use Lesson Insights and that roughly 75% of active learners continue engaging with it more than a year after adoption.
Internal adoption and measurable results
Preply introduced ChatGPT Enterprise across the company and ran enablement sessions for more than 600 employees in New York, Kyiv, London and Barcelona. Weekly active usage reportedly rose from 60% to 95%. The company also embeds custom GPTs, such as Brand Voice GPT, into daily workflows and uses OpenAI APIs for customer service and operational automation.
On engineering workflows, Preply reports that around 94% of engineers use Codex and AI coding assistants for code generation, PR reviews and debugging. Company‑reported metrics for Lesson Insights include more than 70% tutor adoption, a 4.7/5 satisfaction rating from over 300,000 ratings, and a 70% product market fit score.
Co‑founder and CTO Dmytro Voloshyn described the approach as combining human teaching strengths—motivation and cultural nuance—with AI to handle repetitive tasks. Preply says it plans to expand Lesson Insights to capture learners’ goals, progress and preferences over months of study to further personalize pacing and curriculum recommendations.
