Use tool ↗About LinkerTube
LinkerTube adds a sidebar to YouTube that shows subtitles and translations while you watch, and lets you save unfamiliar words with a single click. Saved words go into a spaced-repetition review queue, and each one links back to the exact video moment where you found it for context. It's aimed at English learners who want to study from videos they'd watch anyway rather than a separate course. The core product is free with cloud sync; a Pro plan layers on an AI coaching feature and unlimited vocabulary for $9 a month, $79 a year, or a $199 one-time lifetime option discounted from $500.

Pros & cons of LinkerTube
LinkerTube is a solid pick for someone who already watches a lot of English-language YouTube and wants to turn that into vocabulary practice without switching apps. The free tier covers the core loop of saving and reviewing words; the Pro coaching layer is a nice-to-have rather than essential.
Pros
- One-click word saving directly from YouTube subtitles
- Links each saved word back to its video timestamp
- Spaced-repetition review built in
- Free tier includes cloud sync, not just local storage
Cons
- English-learning focus only, not multi-language
- AI coach and unlimited vocabulary require the $9/month Pro plan
- No company name or location disclosed
Best for
- English learners who watch YouTube regularly
- People who prefer learning vocabulary in video context over flashcard decks alone
- Users wanting cross-device sync of saved words
Not for
- Learners of languages other than English
- Anyone wanting a full course curriculum rather than incidental vocabulary capture
