LoopLab: Shadowing & Listening
Learn languages from YouTube
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Understand real speech one sentence at a time: loop any line from YouTube, tap a word for its meaning, and get AI explanations in your language.
LoopLab helps you understand fast, real speech - one sentence at a time.
Loop any sentence until every word is clear. Tap a word to see what it means in that sentence. Shadow the speaker at your own pace. Your practice follows you between your iPhone, your iPad, and LoopLab for Chrome on your computer.
LOOP ANY SENTENCE
- Loop a whole sentence, or set A and B on exact words.
- Repeat x3, x5, or endlessly, slow down to 0.75x or 0.5x, and add a pause for your turn to speak.
- Hide a saved loop's text, listen again, then check what you heard.
LEARN FROM YOUTUBE
- In the YouTube app, tap Share > LoopLab. The video is saved in Your videos, ready to loop.
- Set A/B on the part you can't hear and save the loop. Today brings your saved loops back for review.
- With LoopLab for Chrome on your computer, the same video opens with subtitles and word-exact loops, and your loops sync both ways.
EVERY WORD EXPLAINED
- Tap or long-press a word for its meaning, from the lesson glossary, the dictionary, or an offline dictionary.
- AI explains what a word means in this very sentence, in your language (English, Korean, Japanese, Chinese, Spanish, Portuguese, and more).
- Words you save in LoopLab for Chrome come to your phone with the moment you heard them; mark them as known as you learn.
LESSONS WITH REAL SPEAKERS
- Free lessons in English, Spanish, French, and German: real people, real speed, every word timed.
- LoopLab Enhanced videos: when a creator adds a word-timed lesson to their YouTube video, LoopLab opens it with subtitles, word loops, and meanings.
