Tran Viet Hoang - Senior student of Data Science, Fulbright University

The most incredible learning tool I've ever encountered, not only for English but also for acquiring knowledge!

  • Now I can easily read documents on Data Science and expand my knowledge, even if there are many new terms from the field. Whenever I encounter new words or find difficult concepts, I simply use eJOY AI to look them up and save them for further learning. It's incredibly convenient, accurate, and fast.
