Mimi
Read full descriptionHide full description
"I know the grammar, but I freeze when I speak." Mimi is for exactly those people. Instead of passively watching, you take a clip from a YouTube video you actually care about and actively listen, rebuild, and speak it β shadowing until English lives in your mouth, not just your notes. β Your own videos Import any YouTube video, clip a 1-30s segment, loop it. Split it sentence-by-sentence and master one line at a time. β Listen β dictation Hide the transcript, type what you hear. See exactly what your ear dropped. β Order β think in English Tap English chunks into English word order β a Korean-style order literally will not fit. β Produce β say it for real Read a real situation, type your English answer, compare to a model. β AI breakdown per clip Literal translation, key expressions, vocabulary, prepositions β every segment, fully unpacked. β Review (SRS) Meet what you learned again right before you would forget it. Stop letting English wash over you. Your videos, your voice.
