Watch any YouTube video with Korean subtitles overlaid on the player, or download a Korean SRT/VTT/ASS file. Works on English tech tutorials, Japanese anime, Chinese variety shows, Spanish news, and any of 30+ source languages. 50 free credits at signup — no card required.
Pick the workflow that matches how you watch. Both use the same AI translation engine and produce the same Korean output.
Install the VinnerVi browser extension, open any YouTube video, click the extension icon, and pick Korean (ko). Korean subtitles appear on the YouTube player, synced to playback. When YouTube already has captions in the source language, VinnerVi translates them at 1 credit per minute. When it doesn't, the extension transcribes the audio with AI first at 3 credits per minute. Korean translations are cached locally and reload instantly the next time you open the same video.
Open vinnervi.com/subtitles, paste the YouTube URL, pick Korean as the target language and a subtitle format (SRT, VTT, ASS, or TXT), and hit Generate. About 1–10 minutes later the finished Korean subtitle file lands in your Jobs tab and your inbox. Drop the file into Premiere, Final Cut, DaVinci, VLC, mpv, or upload to YouTube Studio.
Korean viewers consume a wide range of foreign-language YouTube content — English-language tech tutorials and lectures from US universities and creators, Japanese anime AMVs and gaming streams, Chinese variety shows and dramas, English news and current affairs, foreign-language music videos. Korea has high English proficiency among tech workers and university students, but the gap between "I can read this" and "I can follow casual creator speech at conversational speed" is real. YouTube's auto-translate to Korean exists but suffers the same inconsistency issues other auto-translation tools have — proper nouns get mangled, casual speech gets translated literally, and technical terms often come through wrong.
VinnerVi delivers AI-translated Korean subtitles on any YouTube video. The browser extension overlays Korean captions directly on the YouTube player as the video plays. The URL workflow gives a downloadable Korean subtitle file — useful for editors producing Korean-localized versions of foreign content, language learners studying English/Japanese/Chinese via YouTube, content reviewers working from foreign-language source material, or archivists building Korean-language libraries.
The Korean output defaults to 해요체 polite register, which is the standard convention for Korean subtitle work and feels natural across most video content. Word choice adapts to context: formal news segments and lectures get formal-polite phrasing; casual creator content and gaming streams use appropriate informal speech. If YouTube already has captions in the source language, VinnerVi translates those into Korean at the discounted rate of 1 credit per minute. If not, the audio-transcription pipeline produces fresh Korean captions at 3 credits per minute — useful for amateur uploads, livestream replays, and creator content where YouTube's auto-captions are unusable.
