Unlimited YouTube AI Video Translator
Stop reading subtitles. AI voice dubbing for any YouTube video in 50+ languages. No account, no setup β install and start listening. You open a YouTube video. The speaker is explaining something important while showing code, diagrams, or a map on screen. But you can't read subtitles and watch the visuals at the same time. You're forced to choose β miss what's on screen or miss what's being said. Either way, you lose half the content. YouTube AI Dubber solves this completely. Instead of translating text into subtitles, it generates actual AI voice dubbing in your native language. You hear the video. You watch the screen. You understand everything β the way the content was meant to be experienced. THE ONLY CHROME EXTENSION THAT DUBS YOUTUBE VIDEOS Other tools translate text and display it on screen. This extension generates real audio in your language β you hear the video spoken in your language, synchronized with the content. Tutorials, documentaries, lectures, interviews, entertainment β everything YouTube has, now in your language. Built specifically for YouTube. Works right inside your YouTube player β no external apps, no file downloads, no complicated configuration. 1. Click "Add to Chrome" to install the extension. 2. Open any YouTube video. 3. Select your target language from the extension panel. 4. Hit "Generate" and listen to the video dubbed with AI voice. No account. No signup. No setup. Open a video β pick your language β listen. WHAT YOU GET ποΈ Real AI voice dubbing β not just subtitles Other tools give you translated text on screen. This extension generates actual spoken audio in your language. You hear the video β no reading required. It's the difference between watching a foreign film with subtitles and hearing the fully dubbed version. π 50+ languages supported Spanish, Turkish, Hindi, Japanese, Arabic, German, French, Portuguese, Korean, Vietnamese, Italian, Dutch, Polish, Swedish, and 35+ more. One of the widest language coverages for YouTube dubbing available today. πΎ Saved for instant replay Once generated, your dubbed audio is cached locally in your browser. Come back to any video anytime β instant playback, no waiting, no re-generating. Your dubbing library stays with you. π Complete privacy β everything runs in your browser No videos uploaded anywhere. No audio sent to external servers. No tracking. No account required. The extension reads subtitles, translates them, and generates audio β all locally inside Chrome. ποΈ Full control over playback Adjust dubbing volume independently from the original audio. Switch between dubbed audio and subtitles-only mode. Mute the original audio and hear only the dubbed version. You control exactly how you watch every video. The extension reads the subtitles available on the YouTube video β either manual captions uploaded by the creator, or YouTube's auto-generated captions. It translates them using AI translation engines, then generates natural-sounding voice dubbing using Text-to-Speech technology, all directly inside Chrome. The dubbed audio is saved in your browser's local storage. When you replay the video, it loads instantly. No re-generating, no waiting. Your dubbed videos stay available as long as you want them. Works on any YouTube video that has subtitles β which covers the vast majority of videos on the platform. YouTube auto-generates captions for most videos, so even if the creator didn't add subtitles manually, you can still get dubbing. WHO THIS IS FOR β People who watch tutorials, lectures, and educational videos in a language they don't fully understand. Instead of reading subtitles and missing the visuals, they now listen and watch at the same time. β Researchers, journalists, and professionals who access international content β conferences, talks, interviews, news β in languages other than their own. β Anyone who has ever paused a video just to finish reading a subtitle. This extension lets you watch without pausing, without reading, without missing anything on screen.

Some videos have no subtitles at all, and those cannot be dubbed because the extension reads existing captions rather than transcribing audio directly. This is a technical limitation of Chrome extensions due to browser security policies (CORS). β Is my data safe? π‘ Everything runs in your browser. No videos, no audio, and no personal data are uploaded to any server. No tracking. No account required. Your API keys, if you use any, are stored locally in your browser only. β What if the dubbed voice speaks in the wrong language? π‘ Browser Text-to-Speech uses voice packs installed in your operating system. If the voice for your target language isn't installed, the browser may fall back to a default language. You can install additional language voice packs through your OS settings β Windows, macOS, and Linux all support this. After installing, restart Chrome for the new voices to appear. β How long does generation take? π‘ It depends on the video length and your computer's resources, since processing runs locally. For most videos, generation completes within a few minutes. Once generated, playback is always instant and cached locally. β How many languages are supported? π‘ 50+ languages, covering most major languages worldwide. If you need a specific language that isn't listed yet, send feedback through the extension panel β I actively add languages based on user requests. β Why doesn't it work on videos without subtitles? π‘ The extension reads existing subtitles to generate translations and dubbing. It cannot transcribe audio directly due to how Chrome extensions work and browser CORS security policies. This is a known limitation β there is a plan to work around this in the future, but for now the extension works with videos that have captions available. β Found a bug or want to suggest a feature? π‘ Use the feedback form in the extension panel. I read every message personally and respond. Every weekly update ships features and fixes based on real user feedback. Install now β Open any YouTube video β Hear it in your language.
