Learn Korean from what you are already watching
Korwid puts the reading, the real pronunciation and the speech level under the Korean subtitle — on the video, while it plays.
오빠, 저 사실 그때 좋아했거든요.Polite
oppa, jeo sasil geuttae joahaetgeodeunyo
I actually liked you back then.
Ends in ‑거든요 — 해요체. She is being courteous, not formal.
Three lines, not a translation
The subtitle stays where it is. Korwid adds what you cannot get from the Korean line alone, and nothing else.
- Line 1 — the Korean, split into wordsWord boundaries are marked so you can tell where one word ends. A speech-level badge sits inline at the end.
- Line 2 — the readingRevised Romanization, or the spoken form once the sound changes are applied. You choose which one.
- Line 3 — the EnglishThe subtitle track's own English line, kept as a fallback rather than a crutch.
Korean is not read the way it is spelled
Seven sound changes turn the written line into the one you actually hear. Korwid applies them to every line, automatically.
- Liaison — the final consonant moves right
- Tensification — plain consonants harden
- Nasalization — stops become nasals
- Lateralization — ㄴ and ㄹ merge
- Aspiration — ㅎ fuses instead of vanishing
- Palatalization — ㄷ (d) and ㅌ (t) before 이 (i)
- Contraction in casual speech

You can hear the words. You cannot hear the distance.
Korean marks how close two people are in almost every sentence ending. The badge names it, so you are not guessing.
- Formal합쇼체 hapsyoche — ‑습니다/‑ㅂ니다 (‑seumnida / ‑mnida). News, announcements, speaking to strangers.
- Polite해요체 haeyoche — ‑아요/‑어요 (‑ayo / ‑eoyo). Everyday courtesy with people you are not close to.
- Casual해체 haeche — plain endings. Close friends, family, or someone younger.
When the ending is ambiguous, no badge is drawn. A missing badge is better than a wrong one. How the three levels work →
Words you can actually look up
A conjugated verb is not in the dictionary. Tap a word and Korwid gives you the form that is.
The eight irregular patterns are handled, so the ones that change shape still resolve.
Where it works
Not supported: YouTube Shorts, live streams and picture-in-picture. Videos without Korean subtitles are skipped. Korwid is a desktop Chrome extension — we are not affiliated with YouTube or Netflix.
What happens to the text
Subtitle text is sent to our servers for analysis, and is discarded immediately after the response. What remains on our servers is a hash of the text and the analysis result.
