You know the feeling: the host says something, you catch about 80% of it, and by the time you've worked out the missing word they're two sentences ahead.
The player keeps the transcript moving with the audio and highlights the line being spoken. Tap any word to see what it means, hear it pronounced, and add it to a deck — without pausing. Slow the audio to 0.5× when a stretch is too fast, or push it to 2× when it's too easy.
