Preply was founded in Kyiv, Ukraine as a tutor matching marketplace that uses machine learning to increase the efficiency of pairing  students with language tutors around the world. After this early success, Preply decided to build a full online language learning platform, integrating tutor matching with a virtual classroom for live one-on-one lessons.

Now with offices around the world, Preply has an unparalleled network of over 40,000 verified tutors teaching 50 languages to tens of thousands of students in over 185 countries. Preply is dedicated to providing the highest quality online learning experience with the goal of becoming the #1 marketplace for online language tutoring in the world.

“We realized that we couldn’t provide the best quality experience for students if they had to move to another platform for lessons after finding a tutor. We decided to create a seamless learning experience where students can find a tutor, schedule a lesson, pay, and meet for interactive lessons all on one integrated platform.”

The Power of Real-Time Engagement

Preply’s innovative tutoring platform uses a proven language-learning methodology and focuses on real-time engagement between students and tutors. The platform allows students to choose the context for their language learning with options like learning English for business use. The real-time nature of Preply’s lessons make them more effective than pre-recorded language curriculums.

The lesson experience is designed to facilitate interaction, featuring a split-screen with both tutor and student videos on one side and the lesson materials on the other. Preply also offers an audio-only mode which has helped retain customers who have challenging network connections. To make lessons even more interactive, Preply is working to implement a new virtual whiteboard feature that will allow students and tutors to draw in the same area.
