LeitnerPlus: Learn languages with YouTube & Netflix

Learn languages from the videos you already watch. LeitnerPlus adds dual subtitles and a hover dictionary to YouTube, YouTube Music and Netflix, and turns the words you add into flashcards in your free LeitnerPlus account. WATCH WITH DUAL SUBTITLES • See subtitles in the language you learn and in your own language at the same time. • Follow the whole video in the Transcript next to the player: the playing line is highlighted, every line has its translation, and a click jumps to it. • Pause, repeat and move line by line with the subtitle controls. LOOK UP ANY WORD • Hover a word in the subtitles to see its meanings in your language (provided by Google Translate) and the line it came from. • Read phonetics for Chinese (pinyin), Japanese (hiragana or romaji) and Korean (romanization). • Hear a word with your browser's built-in voices. ADD CARDS TO LEITNERPLUS • Add a word, a phrase or a whole line as a LeitnerPlus card with one click: press Add card in the hover card, or select text and press Add card. Already a card? Add example adds this line to it. • Each card keeps the moment it came from: the subtitle line, its translation and the time in the video, so you can go back to it. • Subtitles colour words by their card state, so you can see at a glance what is new, what you are learning and what you already know. • See all your cards in the Cards tab, with their state and the moment in the video; one click plays that scene again. • The toolbar icon shows how many cards are due; review them on leitnerplus.com or in the Practice tab. • From the Cards and Practice tabs, open the review of this video's or this channel's cards on leitnerplus.com in one click. PRACTICE WITH THE VIDEO • Review: this video's due cards with the word blanked in its line, then Again, Hard, Good or Easy (spaced repetition). • Shadowing: a line plays, the video pauses, you repeat it out loud, and it continues. • Dictation: listen to a line and type the missing words. KEYBOARD SHORTCUTS • Shift+V subtitles on/off, Shift+B sidebar, Shift+F search the Transcript. • Shift+A / Shift+R / Shift+D previous, repeat and next line; Shift+S adds the current line as a card. • In Review: Space reveals the answer, 1–4 grades it. All shortcuts can be changed in the settings. EXPORT SUBTITLES • Download the subtitles of a video as text, or, signed in to your free account, as CSV, JSON, HTML or an Anki deck (.apkg). WORKS ON • YouTube, YouTube Music (after you allow access to music.youtube.com) and Netflix, in Chrome and Edge on desktop. FREE AND PRIVATE • The extension and your LeitnerPlus account are free. • No advertising, and we do not sell your data. Anonymous usage counts (which feature was used, never which video or word) help us improve the extension; switch them off any time in Settings › Account. • Read what is stored and how to delete it: https://www.leitnerplus.com/extension/privacy Questions? support@leitnerplus.com · https://www.leitnerplus.com/help#extension YouTube and Netflix are trademarks of their owners.
