Neko Dub de Nguyên Lê

Neko Dub dubs foreign-language videos into your language with AI: translated subtitles plus natural-sounding voice-over, played in sync with the original video.

HOW IT WORKS
Open a video, pick your target language and voice, and press Dub. Neko Dub reads the video's captions, translates them with AI, and speaks the translation over the video. The original audio is lowered so you can still follow the video.

KEY FEATURES
• AI dubbing – context-aware translation, not word-by-word, so the speech sounds natural.
• Works without captions – if a video has no usable subtitles, speech recognition generates a transcript.
• Many voices – built-in text-to-speech voices, plus optional voice cloning with your own OmniVoice server.
• Translate-only mode – show translated subtitles without voice-over.
• Custom vocabulary – set how names and technical terms should be translated.
• Background music option and separate volume controls for the original audio and the dub.
• Sync across devices – settings, vocabulary and cloned voices (Pro/Max plans).
• Interface available in English and Vietnamese.

SUPPORTED SITES
YouTube, Udemy and Bilibili work out of the box. Coursera, Domestika and Three.js Journey can be enabled one by one from the popup, and Neko Dub asks for access to a site only when you turn it on.

ACCOUNT AND PRIVACY
Sign in with Google to use the service. Free and paid plans include different amounts of dubbing time. Neko Dub only processes the video you choose to dub, and it does not read other pages.
