Every word in the line is listed on the left as it plays, so you can read all the
definitions without clicking on or pointing at anything. The video keeps playing
underneath, and the panel's transparency is adjustable. The subtitle overlay sits
below Netflix's own subtitles by default. If you prefer a single line, you can switch
on Replace player subtitles in the plugin's options.

What it does
Works on Netflix, on Crunchyroll, and on YouTube videos with Japanese captions.
Crunchyroll has no Japanese subtitle track (and some Netflix titles have none either), so there the plugin fetches the episode's Japanese subtitles from a public archive and syncs them to your stream automatically by listening to the rhythm of the dialogue. That takes a minute or two the first time and is instant on episodes seen before. Films are supported too.
Splits the current Japanese subtitle line into real vocabulary words.
Lists every word of the current line in a panel at the left, with reading, JLPT level, and meaning, updating as the show plays.
Keeps a conjugated form together as one entry and names it, so 言ってる is one line labelled progressive.
When you pause the video, the subtitles and their definitions continue to appear, even if a Netflix advertisement makes the main subtitles go away.
Hover or tap a word under the subtitle for its full entry, including romaji and part of speech.
Click a word to open its full usage page on this site, with real example sentences from a Japanese corpus, related words, and how common it is.
Drag the list anywhere over the picture and resize it to taste.
Prefer it off the picture entirely? Switch it into a separate window that floats above everything, even in fullscreen.
A Netflix or Crunchyroll account for those services. YouTube needs none.
On YouTube: a video with Japanese captions, switched on. The plugin reads the
caption text on screen.
On Netflix: Japanese subtitles switched on give the best experience. When they're
off, or the title has no Japanese subtitle track at all (films included), the plugin
falls back to fetching the Japanese subtitles from the public archive and syncing them
to your stream the same way it does on Crunchyroll.
