TubeVocab is an AI-powered English learning platform that helps learners build vocabulary from real YouTube videos. Users paste a YouTube video link, watch it with interactive subtitles, and click unfamiliar words to instantly generate AI-powered flashcards. Each card includes pronunciation, translation, contextual meaning, example sentences, and related vocabulary, with the original video timestamp preserved for contextual review. TubeVocab also provides six practice modes, including flashcards, dictation, cloze tests, speed review, matching games, and mixed practice. Its spaced-repetition system helps learners retain vocabulary over time, while support for translations in 57 native languages makes it accessible to learners from different language backgrounds. Users can also export vocabulary to PDF or Anki.
