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. DATA USE & PRIVACY VinnerVi reads the current video page to detect the video and its available captions. Nothing from the page is sent for translation until you choose a mode and confirm Translate. Subtitle mode sends the selected video URL, language choices, and caption text/timing to VinnerVi and Google Gemini. Speech mode sends the video URL and language choices to VinnerVi; our service retrieves the video's audio and sends temporary audio segments to Groq for transcription. The extension stores your sign-in session, settings, requested job URLs/status, and completed subtitles in browser storage. We also collect pseudonymous product-use analytics and standard service logs to operate, secure, and improve the service. We do not sell user data, use it for ads, or collect unrelated browsing history. Full collection, storage, retention, and sharing details: https://vinnervi.com/privacy/ AI SUBTITLE TRANSLATION Subtitle Translation — If a video already has subtitles, VinnerVi translates them directly. Fast, accurate, and about 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 little background noise. Streaming Mode — On supported streaming services, VinnerVi translates the subtitles the service already shows, live on the player as you watch. Turn on the player's subtitles, press play, and pick your language in the extension. Bilingual by default, about 1 credit per minute. DOWNLOAD SUBTITLE FILES Export your translated subtitles as files you can use in video editors and media players. Download them at vinnervi.com/subtitles. SUBTITLE OVERLAY Translated subtitles appear directly on the video as you watch. They are synced to playback and saved in your browser, so they load again automatically when you come back to the video.
