dubly.me – AI Dubbing and Translated Subtitles for YouTube and Online Courses Watch any video in your language. dubly.me translates what is said in real time, while it plays — hear it spoken aloud, follow it as on-screen text, or both at once. TWO WAYS TO WATCH Dubbing: natural AI speech plays over the original, which is turned down. Made for lectures, tutorials and courses — you listen and keep your eyes on the slides, no pausing. Subtitles: keep the original sound and read along. Pick "Subtitles" in the popup and no voice is generated at all — only the captions appear. Made for films, series and anyone who prefers reading to a voice-over. Use both together — handy for learners. Both ways count towards the same daily minutes. HOW IT WORKS It picks up the video's own subtitle track and translates it: on the free plan with YouTube's own auto-translate, on Basic optionally with AI that fits each sentence to the speech timing. The result is then spoken, shown on screen, or both — you switch either one on or off at any time. Every plan uses the same engine and the same 322 voices; on the free plan you choose female or male, and Basic lets you pick the exact one you like. MORE WAYS TO FOLLOW ALONG - Two-language subtitles: the original line right under the translation - Subtitle look: high contrast, no background or light, in the size you like - With headphones: the original in your left ear, the dubbed voice in your right - Missed a sentence? Alt+Shift+R repeats it - For language learners: sentence by sentence — the original first, a short pause, then the dubbed voice repeats it - Download the subtitles as an .srt file: translation, original or both - Pauses during YouTube ads and picks up right where the video left off SUPPORTED PLATFORMS The free plan works on YouTube. With Basic, YouTube, Netflix, Udemy, Coursera and Vimeo get dedicated support: the controls sit right in the site's own player. On other sites it works with the Basic plan when the page plays a plain video file. 115 LANGUAGES, 322 VOICES The list includes English, Spanish, French, German, Portuguese, Hindi, Arabic, Chinese, Japanese and Korean. Translated subtitles work in 169 languages: all 115 above and 54 more. 76 of them have their own native neural voices; the other 39 borrow a related or multilingual voice, so you may hear an accent. The extension's interface — the popup and the controls on the player — is translated into 120 languages. FREE AND BASIC PLANS - Free: YouTube, with YouTube's auto-translate — try it right away without an account (10 minutes a day), or 30 minutes a day with a free account; female or male voice, no credit card required - Basic (€5/month): up to 9 hours of dubbing a day on all platforms, AI translation as an option (fits the speech timing), choose your own voice, translation style (polite, plain language or close to the original) and metric units, a summary and chapters of the video without starting a dub, dubbing for videos without a subtitle track (on sites other than YouTube), email support PRIVACY FIRST dubly.me does not store what you watch or its audio, and does not read cookies or logins from the sites you visit. Subtitle text is sent to our translation and speech providers, and nothing they receive is retained. On paid plans, a video with no subtitle track of its own (on sites other than YouTube) can have its audio transcribed instead — the audio is processed and discarded, never stored. No data sold to third parties. Full details: dubly.me/privacy WHY DUBLY.ME? Language learning: follow lectures, documentaries and talks you would otherwise struggle with — keep the original audio with text in your language, or switch back to the original alone to train your ear. Accessibility: translated captions for viewers who are deaf or hard of hearing, and speech for those who find reading tiring. Productivity: watch tutorials and courses in your own language without pausing to read. Films and culture: explore international channels and foreign films with translated subtitles, the original performances left untouched.
