Learn languages from the videos you already watch. LeitnerPlus is a Safari extension that adds dual subtitles and a tap dictionary to YouTube, 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: the playing line is highlighted, every line has its translation, and each line can be played again with one tap.
• Search the Transcript to find the moment a word was said.
LOOK UP ANY WORD
• Tap 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).
ADD CARDS TO LEITNERPLUS
• Add a word or a whole line as a LeitnerPlus card with one tap. For a phrase, press and hold in the Transcript, select it and tap Add card.
• 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 your cards of the video in the Cards tab, and review them on leitnerplus.com.
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.
YOUR LEARNING DAY
• Ten minutes with LeitnerPlus subtitles or 5 reviews keep your day, and your streak grows.
• Two rings show today: Watch for the minutes with subtitles, Remember for the reviews toward your daily goal. Close both for a full day.
• Pause days cover a day you miss, on their own: the first at a 3-day streak, then one every 7 days, and one more for every seventh full day. Hold up to 2.
• See your day in the panel next to the video and in the extension's popup, whose flame fills in once today is kept. The Transcript shows how many of the video's words are already in your cards.
• "Open your day" in the popup opens your day on leitnerplus.com: tonight's picks and the shows and channels you keep words from.
ON IPAD AND IPHONE
• iPad: the Transcript sits beside the video in landscape and under it in portrait. One button shows the video full screen with the Transcript beside it.
• iPhone: YouTube opens its mobile site in Safari. A bar "Open with LeitnerPlus" switches the video to the view the extension works on.
HOW TO START
1. Open the LeitnerPlus app once. It shows the two steps with pictures.
2. In Safari, switch LeitnerPlus on under Manage Extensions and allow it on youtube.com and leitnerplus.com.
3. Open a YouTube video that has subtitles.
FREE AND PRIVATE
• The extension and your LeitnerPlus account are free.
• Count watching toward your streak (on unless you switch it off): your LeitnerPlus account keeps which videos you watched with LeitnerPlus subtitles and for how many minutes, so they count toward your streak. Only you see them, videos are kept for 13 months, and you can turn it off or clear them in the settings.
• 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 and general.
