Jupjup – Learn Korean from videos & websites Autor: Ian

Pick up Korean from the things you already watch and read.

Jupjup (줍줍, Korean slang for "picking things up") is a sentence-mining tool. It finds the sentences you can almost understand, so you learn new words in context, from content you actually enjoy.

HOW IT WORKS
• Tell Jupjup roughly how many words you know, then browse as usual.
• In any sentence where you know every word but one, that word gets a green underline.
• Hover it (or any Korean word) to see its dictionary form, meaning, how common it is, and how it's built.
• Click "Save" to turn the word or sentence into a flashcard, with a link back to the exact moment in the video.
• Review with spaced repetition (FSRS, the algorithm built into Anki), or send everything to Anki in one click.

FEATURES
• Hover lookups for any Korean word on any page
• Clickable Korean subtitles on YouTube, Netflix, and other video sites (bilingual subtitles keep the English line)
• Grammar explained in plain English: over 100 particles, endings, and patterns
• Progress dashboard: how much everyday Korean you know, words learned over time, streaks, and upcoming reviews
• Library to search, edit, and delete everything you've saved
• On YouTube: see how much of a video you'll understand, and the new words said most often in it
• Sentences you can now read in full get a soft highlight
• Practice both ways: Korean → English, then English → Korean once a word sticks
• Optional: keep the line's audio from the video with your card (YouTube and most players)
• Home shows the words you keep running into (with the sentence you met them in) and your time with Korean
• Optional and experimental: read Korean in images, like webtoon panels and posters (offline)
• Send your cards to Anki (via AnkiConnect) or export a file

PROMISES
• No AI: real Korean, human-written dictionaries, nothing generated
• Private: everything stays in your browser; no account, no tracking
• Offline: the Korean analyzer and dictionary run on your computer
