About Malggu Grammar Master

Malggu Grammar Master helps English-speaking learners study Korean grammar while watching Netflix or YouTube. WHY INSTALL • Spot grammar as it appears in real dialogue — not isolated textbook drills • Dual KO/EN captions on the player so you can follow meaning without pausing every line • Adjust caption size and sentence-structure (Blocks) size to fit your screen • Hover or tap a word to see every listed sense for polysemous vocabulary (context pick highlighted) • Frequency view: see which patterns show up most in the episode you’re watching • Practice loops: jump back to a line and repeat the scene • Pronounce: type a Korean word or short sentence and watch lip + mouth animations, syllable by syllable (Pro+). Hear pauses the video so the show audio does not overlap HOW IT WORKS Open Netflix or YouTube with Korean captions Open the Grammar Master side panel Watch Live highlights, check Frequency, then open Explain or Practice for a pattern Optional: open the Pronounce tab and type a word you want to say — not a drama caption PRIVACY • Subtitle/dialogue text is not uploaded to our servers or to any LLM • Captions may stay in your browser session while Matching is on; they are cleared when you pause Matching • Matching runs on-device — we do not sell your watch history as content • If you are signed in, Korean you type in Pronounce is saved as your studio line. Drama captions are never saved that way. Signed-out typing stays on this device only • Unlimited Explain unlocks after you sign in and agree to Malggu email updates (unsubscribe locks it again). Without Agree, logged-in free accounts get a small daily Explain quota. Membership adds study tools like Pronounce, quiz, and AI grammar tutor (coins) — not the core matching experience BEST FOR Learners who already understand basic Korean and want to notice grammar in real shows and videos.
