Watch any Rakuten Viki K-drama, C-drama, or Asian show with bilingual subtitles — the original caption and your language, side by side on the player. VinnerVi reads Viki's own subtitle track and translates it live, even when Viki has no track in your language. 50 free subtitle-minutes at signup — no card required.
There's nothing to download and no file to manage. The browser extension reads the subtitles Viki already streams and overlays a translation on the player as you watch — three steps, then it just works on every episode.
Viki's subtitles are produced by volunteer communities, so a hit K-drama might have twenty languages while a niche C-drama or a brand-new release has two or three — and yours may not be one of them. Instead of waiting days or weeks for volunteers, VinnerVi takes whichever subtitle track is available — usually English — and translates it into your language live on the player: Spanish, Hindi, Vietnamese, Indonesian, Thai, Turkish, Arabic, Portuguese, and dozens more.
Streaming Mode translates the subtitles Viki already provides, so there's no audio to transcribe. That makes it about three times cheaper than full-audio translation — around 1 credit per minute — and more accurate, because it starts from the captions a human translator already wrote rather than guessing from the soundtrack.
By default both lines stay on screen: the original caption on top, your language underneath. Viewers learning Korean from K-dramas keep the source line for study; everyone else just reads their own language and enjoys the show. The translation is synced to playback frame by frame, so it never drifts out of time with the dialogue.
Rakuten Viki built its catalogue on community translation — passionate fans subtitling Korean, Chinese, Japanese, Thai, and Turkish dramas for a global audience. It's a remarkable system, but it's uneven by design: blockbuster titles get dozens of languages within hours, while quieter shows, older series, and same-day premieres can sit with only one or two tracks for a long time. If your language is the one that's missing, the wait can outlast your interest in the show.
VinnerVi fills that gap without touching the video. It runs entirely in your browser, reads the caption text Viki is already displaying, sends only that text for AI translation, and paints the result back onto the player in real time. Nothing is downloaded, re-hosted, or shared — the episode still streams from Viki exactly as before, and your account stays in good standing.
Because it works from the existing caption track, the translation inherits the timing and the names the fan-subbers got right, and renders dialogue in natural, conversational phrasing rather than the literal output of generic auto-translate. It's a favourite with K-drama fans studying Korean, who keep the original line on screen and read their own language beneath it. New accounts get 50 free subtitle-minutes to try it on a full episode before spending anything.
