Subtitles
Read at your own level
Furigana sits over the hard words and steps aside for the ones you know. Turn on romaji, choose the translation language, and set the size you like.
Set the text size, color each word by how well you know it, and show the translation in your language.
Phrases
Learn phrases the way you learn words
Set phrases are underlined right in the subtitles. Tap one to see what the whole phrase means, then save it, review it on its own card and mark how well you know it, just like a word.
AI explanations
Ask why it's said that way
When a line gets tangled, AI breaks it into parts and explains the grammar that holds it together. 10 explanations a day are free.
Wordbook
Every word keeps its sentence
Words you look up are saved with the line, its translation and the video, so you can go back to the moment you heard them.
Review
Review right before you forget
Spaced repetition (FSRS) brings each word back just before it fades. A few minutes a day is enough.
