Anki Chrome extension: flashcards from the videos you watch
An Anki Chrome extension for the words you meet in videos
Anki is a flashcard app that shows each card right before you are likely to forget it. InterSub fills it with words from real videos. Watch Netflix, YouTube, Udemy or Crunchyroll with dual subtitles, hover a word to translate it, star the ones you want to keep, and they sync to an InterSub deck in Anki on your computer and phone. No copying words by hand.
How it works
What is Anki?
Anki is a flashcard app for desktop and mobile built on spaced repetition. Language learners, medical students and anyone with a lot to memorize use it to remember more with less review time.
Why spaced repetition works
Each time you remember a card, Anki shows it again later; each time you forget, sooner. Your review time goes to the words you are about to lose, not to the ones you already know.
Your InterSub Wordbook, now in Anki
InterSub saves every word you look up in subtitles to your Wordbook, a vocabulary builder that fills itself while you watch. Star the words you want to learn, and they sync to the InterSub deck in Anki. Setup takes a few minutes: see the Anki sync guide.
Review vocabulary from the shows you watch
Every card is a word you met in a real scene, which makes it easier to remember than a word from a list. Review vocabulary in Anki, then hear it again in the next episode.Anki + InterSub for any subject
Learning a language from films, following medical school lectures or taking CS50 online: look up the terms you don't know while you watch and learn new words in Anki later.
