Stay in the sentence.
Submersion sits on Netflix and YouTube while you watch. Two caption tracks, meaning on click, and keys to walk the dialogue without leaving the scene.
Built first for English speakers watching Japanese. Other language pairs work too.
夜の教室
How it fits the watch
- Pin Submersion Load the unpacked folder in Chrome, then open a title with captions on.
- Read both lines Study language on the player, gloss underneath. Click a word for reading and meaning.
- Step the dialogue Z last line, X this line again, V the next. Space still belongs to Netflix or YouTube.
What you get
-
Two official tracks
Netflix and YouTube captions you already have. Automatic English if a gloss track is missing.
-
Meaning on click
Jisho for Japanese, translation fallback otherwise. Right-click sets Unseen / Studying / Solid / Skip.
-
Transcript, frequency, kept
Search the running transcript, rank words in this title, keep lines with B.
-
Cover until you look
Hide the study line and uncover on hover. U unblurs when you want the whole sentence.
-
Stop at the end of a line
Optional pause-each-line (P). Speed with − and =. Host play/stop is still Space.
-
Reader and export
