Lingoku runs as a browser extension — no app switching, works instantly on every platform you use.
Anime subtitles become your Japanese tutor
See an unfamiliar kanji? Don't pause, don't screenshot, don't open Jisho. Hover over it — 0.2 seconds later, AI gives you the reading (furigana), meaning, and exactly what it means *in this line of dialogue*. Whether it's 手紙 (tegami — letter) or 手紙 (a misleading Sino-Japanese false friend), the AI gets it right from context.
Works with Netflix, Crunchyroll, YouTube, and any Japanese video content. The words you learn during a climactic anime scene are the ones that stick forever.
Furigana auto-annotation
Readings appear above kanji automatically — no more blocked reading
False friend detection
AI catches Sino-Japanese false friends that trick Chinese speakers
One click saves a word — AI handles memorization
Found a useful expression? Click once. Lingoku generates a complete flashcard: the word, furigana reading, the original sentence from the show, AI's context-specific explanation, keigo politeness level, and JLPT level. No manual organizing. No Anki setup. Spaced repetition resurfaces it right before you'd forget.
One-click save
Instant flashcard with full context, no typing needed
JLPT level tagged
Every word automatically labeled with JLPT level (N5-N1)
Japanese news, tweets, blogs — every page becomes a lesson
Not just anime. Lingoku works on any webpage with Japanese text. Reading NHK News? Kanji auto-annotated with furigana, meanings on hover. Scrolling Japanese Twitter? Internet slang and colloquial expressions get explained in context.
Lingoku remembers words you already know. Only true i+1 words get highlighted — your reading flow stays smooth, your vocabulary grows silently.
Works everywhere
Any Japanese website — news, blogs, social media, manga sites
Keigo recognition
Automatically identifies and explains politeness levels
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 kanji and vocabulary are your i+1 — smart enough to skip kanji you already know from your native language background.
Context memory beats flashcards 3:1
Kanji and words encountered in anime and shows you love have 3x better retention than isolated kanji drills. The word gets emotionally anchored to the 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 kanji apps feel like work — and Lingoku doesn't
Not another flashcard system. A completely different approach to Japanese.

Feedback from Chrome Store and Discord community
"Watched anime with subtitles for years — knew what things meant but couldn't read a single kanji. Lingoku's furigana annotation changed everything. Two months in, I'm reading raw manga and recognizing hundreds of kanji I learned from shows."

"JLPT N2 was my goal but kanji drills were killing my motivation. Using Lingoku on Netflix J-dramas, I learned N2 kanji in context without feeling like studying. Passed N2 on my first try — the reading section felt easy because I'd seen those characters in real situations."

"I work with a Japanese team and need to read tech docs and emails. Lingoku's context-aware AI is incredible — it distinguishes between the same kanji used in business vs. casual contexts. My Japanese colleagues say my written communication has improved noticeably."

"The keigo recognition feature is what sold me. Japanese politeness levels always confused me — when to use 尊敬語 vs. 謙譲語. Lingoku labels every expression with its politeness level. After watching enough dramas, I can now instinctively tell what's appropriate in different situations."

"Reading Japanese news was a chore — so many unknown compounds. Lingoku hover translation with furigana and context explanation cut my reading time in half. The AI catches subtle nuances in newspaper Japanese that generic dictionaries miss completely."

"My professor recommended Lingoku as a supplement. Discovered I learn kanji way faster from anime context than from textbooks. The false friend detection is especially helpful — no more confusing 手紙 (letter) with toilet paper or 勉強 (study) with forcing yourself."
