Watch any foreign-language video in Safari with bilingual subtitles — the original and your language, side by side on the player. VinnerVi Subtitles is a native Safari extension on the App Store for Mac, iPhone, and iPad, with Sign in with Apple and 50 free subtitle-minutes at signup — no card required.
Three steps, once — then it works on every video you open. No file uploads, no copy-pasting into a translator, no switching apps.
Listed on the App Store as “Subtitle Translator for Safari”.

The Safari extension covers the same 50+ hand-verified video sites as VinnerVi on every other browser: YouTube, Bilibili, TikTok, X (Twitter), Vimeo, Dailymotion, Niconico, and more. Streaming Mode goes further — on Crunchyroll, Viki, and Amazon Prime Video it reads the show's own subtitle track and translates it live as you watch, even into languages the platform doesn't offer, with Netflix, Disney+, and HBO Max rolling out.
This is not a web wrapper — it is a native Safari App Extension delivered through the App Store and reviewed by Apple, on macOS 12 or later and on iOS and iPadOS 26.2 or later. After signing in with Apple, choose Basic Monthly for 1,800 credits each month or a one-time 1,000-credit top-up. Apple handles every payment; subscriptions renew monthly until canceled, top-up credits never expire, and failed jobs refund credits automatically.
Your Apple account and Apple-purchased credits are used only by the VinnerVi Apple app and its Safari extension. They are separate from VinnerVi web, Chrome, Edge, and Firefox accounts, even if the email address is the same. Using the same Apple identity keeps the Apple balance available across Mac, iPhone, and iPad.
By default VinnerVi keeps both lines on screen: the original caption on top, your language underneath. Language learners keep the source line for study; everyone else simply reads their own language and enjoys the video. The overlay is synced to playback frame by frame, so it never drifts out of time with the dialogue.
Two modes cover every video. When the video already has captions or a subtitle track, VinnerVi translates that track at the lowest rate — about 1 credit per minute. When there are no captions at all, it transcribes the audio with AI speech recognition first, at about 3 credits per minute, so no video is out of reach.
Safari has historically had far fewer translation extensions than Chrome — most subtitle tools never ship an Apple version at all, because a Safari extension must be a signed, sandboxed app distributed through the App Store. The practical result for Mac users has been switching to a second browser just to watch foreign-language video; on iPhone and iPad, going without was usually the only option.
VinnerVi closes that gap. The extension runs entirely inside Safari, reads the caption text or audio of the video you're already watching, sends only that for AI translation, and paints the result back onto the player in real time. Nothing is downloaded or re-hosted; the video keeps streaming from the original site exactly as before.
If you prefer downloadable subtitle files, vinnervi.com/subtitles remains available as a separate web service and account. Paste a video URL there to download SRT, VTT, ASS, or TXT in 30+ languages. Apple purchases and credits do not transfer to or from the website.
