LingoKeep

Learn languages while watching YouTube: dual subtitles, a click-any-word dictionary, one-click flashcards, and free review. Spanish, Japanese, French, German.

LingoKeep adds dual subtitles, a click-any-word dictionary, and one-click flashcards to YouTube. It's free, takes one click, and works on the YouTube videos you already watch. Four steps, and the only new habit is the last one. Open a YouTube video in Spanish, Japanese, French or German. Click a word — or drag across a phrase — and the video pauses on its dictionary entry: dictionary form, reading, part of speech, meanings.
