Lingoku runs as a browser extension — no app switching, works instantly on every platform you use.
K-drama subtitles become your Korean tutor
See an unfamiliar word in the subtitles? Don't pause, don't screenshot, don't open a dictionary app. Hover over it — 0.2 seconds later, AI gives you the reading, meaning, and exactly what it means *in this line*. Whether it's 합니다 (formal) or 해 (casual), the AI identifies the speech level and explains why it's used here.
Works with Netflix, YouTube, and any Korean video content. The words you learn during that heart-fluttering K-drama moment are the ones you'll never forget.

Korean news, webtoons, social media — every page becomes a lesson
Not just K-dramas. Lingoku works on any webpage with Korean text. Reading Naver news? Unknown words auto-highlight with meanings on hover. Browsing Korean webtoons? Dialogue gets explained with speech level context. Scrolling K-pop fan communities? Slang and abbreviations like ㅋㅋ, 헐, 대박 get explained.
Lingoku remembers words you already know — only i+1 words get surfaced. Reading stays smooth, vocabulary grows in the background.

Any Korean website — news, webtoons, social media, forums

Why Lingoku actually works
Decades of linguistics research back this up: real-context acquisition beats rote memorization every time.
Comprehensible input (i+1)
You acquire language best from content slightly above your level. Lingoku's AI identifies exactly which Korean words are your i+1 — smart enough to leverage the 60% of Korean vocabulary that shares Sino roots with your background.
Context memory beats flashcards 3:1
Korean words encountered in K-dramas and variety shows you love have 3x better retention than isolated vocabulary drills. The word gets emotionally anchored to that unforgettable scene.
Spaced repetition fights the forgetting curve
Every word you encounter is tracked. Lingoku resurfaces it at the optimal moment — moving vocabulary into permanent memory instead of this-episode-learned-next-episode-gone.
Why vocab apps feel like work — and Lingoku doesn't
Not another flashcard system. A completely different approach to Korean.

Feedback from Chrome Store and Discord community
"Watched K-dramas with English subs for five years, still couldn't understand without them. Two months with Lingoku, I watched a whole episode with Korean subs only. The hover translations during emotional scenes made the words stick — now I know them without hovering."

"Wanted to understand BTS lives and Weverse posts without waiting for translations. Lingoku works on Weverse — I hover over Korean text and instantly get what it means. Finally understanding my bias's posts in real time is an incredible feeling."

"Work requires browsing Korean fashion sites and Naver blogs daily. Lingoku is an efficiency miracle — hover over unfamiliar Korean and instantly understand. After a month, my reading speed for Korean pages has more than doubled."

"Taking Korean as an elective — grammar was fine but vocabulary was stuck. Professor suggested Lingoku. Watching Korean YouTube vloggers, I've picked up more practical vocabulary in a month than two semesters of class. And it doesn't feel like studying."

"Grew up understanding Korean from parents but couldn't read or write well. Lingoku on Naver and Korean webtoons bridged the gap — seeing words in content I actually enjoy made Hangul reading finally click."

"Korean variety subtitles have so much slang and wordplay that generic translations miss. Lingoku's AI explains the actual nuance — like why everyone laughed at that pun or what that slang abbreviation means. Finally get all the jokes."
