Lanma
Language learning. Live
The lesson above, done with any YouTube video, article or song you share. It leaves out the words you already know, brings the rest back just before you'd forget them, and ends with a voice conversation.

Our first, Lanma, turns a video or an article into a vocabulary lesson. Then it has you say the words aloud. It teaches 20 languages and has its first 100+ learners.
ETHEIA was founded in 2026 by Yu Taek Lee, who spent more than four years at NAVER and worked on MYPLACE, which 15 million people use each month.
Describing a lesson is slower than giving one, so the rest of this page is a lesson. Lanma would pick out the expressions underlined above.

This is an imitation that runs on four expressions from the text above. The app does it with any video or article, adds quizzes and a review schedule, and finishes with a voice conversation.

Exam and course study. In development, under a working title.
StudyLingo does for course material what Lanma does for videos. It cuts slides and lecture notes into short lessons and schedules the reviews, for exam candidates and the academies that prepare them.

“I used to look up every word I did not know while watching. Now I learn not only the expressions from the video but related ways to use them too, which I especially liked.”
