TubeVocab

TubeVocab is an instagram video transcript tool that turns any YouTube video into contextual English vocabulary flashcards. TubeVocab turns YouTube videos into English vocabulary lessons. Paste a link, watch with synced subtitles, and click any word to get an AI flashcard with translation, pronunciation, and context from the scene.

TubeVocab is a vocabulary builder that treats YouTube as its textbook. Rather than handing learners fixed word lists, it lets them paste the URL of any video with English subtitles and then click on unfamiliar words while watching. Each click triggers an AI-generated word card containing phonetic pronunciation, a translation into the learner's native language, a meaning drawn from the scene being watched, example sentences, collocations, synonyms, antonyms, and an illustration. Every card keeps a link back to the timestamp where the word appeared, so review can return to the original moment of learning. The product is aimed at self-directed learners who already consume English media and want to convert that time into structured study. It supports 52 learning languages and explanations in 57 native languages, which makes it usable for learners whose first language is not English as well as for English speakers picking up another language from English-subtitled videos. Six practice modes reuse saved words in different ways: spaced repetition flashcards with recall ratings, dictation where the word is heard and typed with progressive hints, cloze tests built from real video sentences, quick swipe-based speed review, a timed match game pairing words with translations, and a mixed session that shuffles all of them. Because each mode targets a different skill, the same card collection covers recognition, spelling, and reading intuition instead of only passive recall. TubeVocab sits between generic flashcard software and full language courses. It borrows the spaced repetition model familiar from Anki, which it can export to, but supplies the content automatically from authentic video. The tradeoff is that it is a vocabulary and comprehension tool, not a conversation partner or grammar curriculum, and progress depends on credits rather than unlimited study. Accounts start free with 110 credits, enough for roughly 3 videos and 50 cards. Plus runs $8 per month ($60 annually) for 1,500 monthly credits, and Pro is $20 per month ($149 annually) for 5,000 credits. Each video costs 20 credits and each card costs 1.
