Watch foreign videos without the language barrier. VinnerVi is an AI-powered subtitle translator that can transcribe audio and translate subtitles, then overlay them on the video player. AI SUBTITLE TRANSLATION Subtitle Translation — Translate existing video captions in seconds. If a video already has subtitles, VinnerVi translates them directly. Fast, accurate, and just 1 credit per minute. Audio Transcription + Translation — No subtitles on the video? VinnerVi uses AI speech recognition to transcribe the audio, then translates the transcript into your language. Best results with clear speech and minimal background noise. Streaming Mode — translate subtitles on your streaming subscriptions From version 1.5.0 and above: VinnerVi now translates the subtitles your streaming service already shows — live on the player, as you watch. Supported today on Crunchyroll™ and Viki™, with more subscription streaming services on the way. • Bilingual subtitles right on the player — original on top, your language below • Near-instant — we read the show's own subtitle track, so there's no transcription wait • About 1 credit per minute — the same low rate as caption translation • Just open an episode, press play, and pick your language in the extension DOWNLOAD SUBTITLE FILES Export your translated subtitles as downloadable files. VinnerVi generates subtitle files in SRT, VTT, ASS, and TXT formats — use them in video editors, media players, or upload them to your own content. Download at vinnervi.com/subtitles.
