TubeDub – Translate & Dub YouTube

Translate YouTube subtitles and dub videos into 30 languages with natural voices. Free with Google or Bing, or bring your own AI.

TubeDub translates YouTube captions into 30 languages and dubs the video with natural voices, all inside your browser, with no account and no server of ours. New: dub videos that have no subtitles. TubeDub listens to the video and writes the subtitles itself, on your computer (the speech model is downloaded once). • Translate to 30 languages with Google Translate or Bing Translator (free), or use your own OpenAI-compatible AI (OpenAI, Gemini, DeepSeek, OpenRouter or your own server). • Dub with Google voices or Microsoft Edge neural voices (female and male), or keep subtitles only. • Lowers the original audio while the voice speaks; the video slows slightly so the voice can finish each sentence. • Subtitles: dual, translated or off. Full style options with live preview: position, font, weight, color, outline or shadow, background. • Translation rules: fix wrong captions, keep a glossary, correct translations. Subtitles and voice both use your words. • Keyboard shortcuts: Alt+D dubbing on/off, Alt+C switch subtitles, Alt+S swap volumes. • Download translated subtitles as .srt. • Translations and voice clips are cached, so reopening a video is instant. How to use: open a YouTube video, click the TubeDub icon, pick a language and press "Dub this video". The video needs captions (manual or automatic). Privacy: your settings, translations and API key stay in your browser. Text is sent only to the translator you choose (Google, Bing or your own API address).
