Lex
Overview
English teacher for any YouTube video you find interesting. Lexical approach.
Lex turns any YouTube video into an English lesson. Clickable subtitles: tap any word to get its meaning in that exact sentence — not a dictionary list of every possible translation. Video tutor: open the chat and ask anything — what a phrase means, why the grammar works this way, what is happening in the video. The tutor sees the subtitles and answers in context. Voice mode: discuss the video out loud to practice speaking and listening. Dictation: speak your questions instead of typing. Works on videos without subtitles too: Lex can transcribe the speech itself. Lex is a paid service: create an account, top up your balance, and pay only for what you actually use — every request shows its cost. Support: (email)
