AutoSub Original — Original Language Subtitles for YouTube

Automatically selects YouTube subtitles in the video's original language, with your preferred language as a fallback.

AutoSub Original automatically selects YouTube subtitles in the video's original language, and, when you don't understand that language, switches to your own. No more digging through the CC menu on every video. No more English auto-translate on an Italian documentary, or Spanish subtitles on an English interview. AutoSub reads what language the video actually speaks, picks the right subtitle track for you, and does it every time without you touching a thing. HOW IT WORKS - Pick the languages you understand. English, Italian, French, German, Spanish, Japanese and 30+ more. Videos in one of these languages keep their original subtitle track, you watch them without any translation. - Choose a fallback language. When a video is in a language you don't know, AutoSub Original selects your fallback language. If that exact track isn't available, it lets YouTube's auto-translate do the work and sets it to your language automatically. - That's it. Enable it once, and every YouTube video gets the right subtitles. WHY YOU SHOULD INSTALL IT - Always the right subtitles. The original language is honored whenever you can understand it; your language steps in only when it makes sense. - Save time, every day. You stop opening the settings menu and hunting for tracks on video after video, AutoSub handles it in the background. - Full control. Add or remove any number of "languages you understand" and change your fallback whenever you like, straight from the popup. - Private by design. Everything runs locally in your browser. No accounts, no tracking, no data sent to any server, only the `storage` permission, used to remember your language choices. SUPPORTED LANGUAGES (languages you understand + fallback) Arabic, Bulgarian, Chinese, Croatian, Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Romanian, Russian, Serbian, Spanish, Swedish, Thai, Turkish, Ukrainian, Vietnamese. THE EXTRAS - Catch counter: the popup tracks how many manual clicks AutoSub Original saved you, plus the total time you got back. - Enable / disable in one click from the popup master switch. - Works on youtube.com and m.youtube.com. Install AutoSub Original and never think about CC settings again. If it saves you time, a coffee keeps it free, you'll find the support button right in the popup. === PRIVACY DISCLOSURE === AutoSub Original does not collect, store, or transmit any personal data. - No account, no login, no analytics, no advertising identifiers. - The only data saved is your subtitle-language preferences, stored locally with Chrome's own storage API on your device. - No network requests are ever made by the extension. - Third parties: none. No cloud, no backend, no remote code. Permission used: "storage" to remember your language settings locally.
