LenguaZen

LenguaZen turns the videos you already watch into language practice. On YouTube and Netflix it replaces the native subtitles with a clickable subtitle bar for Spanish, French, or Italian: hover a word to peek at its meaning, click it to look it up in context and save it to your LenguaZen Word Bank, and translate a whole line when you need it. Every subtitle you watch through counts as reading exposure in your LenguaZen vocabulary stats, and every word you look up or save comes back for spaced-repetition review in the app. Words already in your Word Bank are highlighted in the subtitles so you notice them in the wild. Features - Clickable subtitles over the YouTube and Netflix players (Netflix support is in beta) - Hover to peek at a word's meaning, click to look it up and save it - Translate the current line - Hover the subtitle bar to hold playback at the end of the line - Keyboard shortcuts: , and . for previous and next line, r to replay, s to toggle the overlay - One-tap add of YouTube videos to your LenguaZen library - Optional watch-time tracking towards your daily goal (off by default) Requires a LenguaZen account (lenguazen.com). Looking words up and saving them needs a paid plan; the subtitle overlay and hover peek work on any account.
