You can almost follow native Japanese — but every video is a wall of words to look up. タマ pulls the vocabulary straight out of the transcript, so you can learn it and watch again.
You've done the textbooks. You know the grammar. But real Japanese content still moves too fast, with too many unknown words to pause and look up one by one.
タマ closes that gap. It reads the transcript, finds the words worth learning, and gives you their readings and meanings — so the video becomes comprehensible input instead of noise.
No setup, no extensions, no dictionaries open in another tab.
Drop in any YouTube video with Japanese audio and captions. A vlog, an interview, a clip you love.
タマ reads the transcript, tokenizes the Japanese, and looks up each word in a dictionary — readings, meanings, and the sentence it came from.
Learn the words with spaced-repetition flashcards, then jump back to the exact moment in the video where each one was said.
Not just a word list — a full loop from video to memory.
Every word becomes a flashcard scheduled by an FSRS algorithm, so you review right before you'd forget.
Turn on beginner mode for readings over every kanji, and tap any word in an example sentence to see its meaning.
Each word remembers the sentence and timestamp it came from — one click replays that exact moment.
See which words belong to which JLPT level, and test yourself with quizzes from N5 to N1.
Start with one link. Build a deck from the Japanese you actually want to watch.
