Turn any YouTube video into your own language lesson
Save words and sentences as you watch, practice pronunciation with word-by-word scoring, dub lines in your own voice, then review every day with spaced repetition — all synced between the Chrome extension and your dashboard.
No credit card needed to try it.

What does your dashboard look like inside?
These are the three main screens you'll use every day — they cycle on their own, or swipe/drag to pick one.
Everything you need, right on the video you're watching
No separate textbook — Lingtune turns the YouTube content you already enjoy into your lessons.
Save words & sentences as you watch
While watching on YouTube, click or hover a word to see its pronunciation, meaning and hear it read aloud — save it to your library in one tap.
Dub it in your own voice
Record each line (or a whole passage in one take), then replay the video with your voice instead of the original — practice speaking with the real rhythm and intonation.
Word-by-word pronunciation scoring
Speech recognition scores you as you read — each word is colored correct/close/wrong, so you know exactly what to practice instead of getting one vague score.
Karaoke-style subtitles
Words light up in time with the video's real voice whenever possible — not every subtitle is estimated — so you keep up with how fast native speakers actually talk.
Spaced-repetition review
Four kinds of drills — listen & type, fill in the blank, reorder words, rewatch the clip — scheduled automatically with the FSRS algorithm, right before you'd forget.
Synced between extension and web
Everything you save with the extension while watching YouTube is right there in your dashboard — learn on your phone, review on your computer, nothing lost.
How it works
Three simple steps, without changing how you watch YouTube.
Install the extension
Add Lingtune to Chrome — a compact panel appears right next to every YouTube video you watch.
Watch & save what you want to learn
Click a word to see its meaning, or pick a whole sentence to save it and record yourself reading it, while watching as usual.
Review & dub on the web
Open your dashboard to review your vocabulary on a spaced-repetition schedule, or go to “Dubbing” to rewatch the whole video in your own voice.
