Builds English vocabulary flashcards from the real subtitles of any YouTube video.
TubeVocab takes a YouTube video URL and pulls its real subtitles into a clickable transcript next to the player, letting learners click unfamiliar words to build AI-generated flashcards with spaced repetition review. The interface and translations are localized into more than 50 languages, so the source content can be any YouTube video while support stays in the learner's own language. Cards can sync to Anki through AnkiConnect or be exported for later import. A free tier is always available without a trial deadline, and TubeVocab Pro adds features for a flat monthly or discounted annual price. It runs in the browser and works on phones, tablets, and desktops without a separate app.
Free tier is always available with no trial expiry; TubeVocab Pro is $8/month or $60/year.
Use tool ↗TubeVocab's advantage is letting a learner study from any YouTube video they already want to watch instead of a fixed library of lessons, and the always-available free tier is more generous than most competitors that gate everything behind a trial. It depends entirely on a video already having usable subtitles, so obscure or auto-caption-only videos will work less well.
