Yes, you can download:
🎧 The dubbed MP3 audio

Vaivox doesn't translate word by word: it understands the content and the context, so the dubbing sounds natural and true to the meaning — not a mechanical translation.

Prices are shown in your local currency automatically, based on your country: euros (€) by default, US dollars ($) in the United States, and British pounds (£) in the United Kingdom.

The plans are the same, at the same value, in every currency — and you always see the exact price in your currency before you pay.

Yes, you can cancel at any time from your account — no commitment, no lock-in.

Yes. Besides YouTube, TikTok and X, Vaivox also dubs Bilibili (China) and VK (Russia) videos into your language — platforms almost no other tool supports. Just paste the link and you get the full video dubbed with a natural voice.

No, the video stays on YouTube: Vaivox doesn't download or re-host it. It only adds the dubbed audio, synced to the original. It's meant for personal use, to help you understand content.

No. Age-restricted videos require signing in to a YouTube account to confirm your age, and Vaivox never uses personal login credentials or cookies — so they can't be processed. Please pick a video that's viewable publicly without signing in.

On purpose. Vaivox is built to help you understand videos, not to create polished content for creators. Perfect lip-sync would make each video far slower and more expensive — and our goal is the opposite: fast, natural understanding at a price everyone can afford. You get an AI voice in your language, synced to the timing of the original, so you can follow along easily.

It depends on your plan: Free up to 30 minutes, and paid plans go up to 60, 120 and 150 minutes per video. If a video is longer than your plan allows, you'll see a message and can upgrade or pick a shorter video.

Your video stays on YouTube — Vaivox doesn't re-host it. We only process it to create the dubbed audio, we never use your content to train AI models, and temporary files are deleted after processing (generally within 90 days).

Vaivox aims for a faithful, natural translation so you truly understand the content — meaning first, not word-for-word. It's built for comprehension: you follow the ideas as if the video were made in your language.

Anything you want to understand: courses, tutorials, interviews, podcasts, lectures, talks and documentaries. Vaivox works great with spoken content — the clearer the speech, the better the result.

No. Your minutes are only used when a dubbing completes successfully. If a video fails, no minutes are deducted — just try another video.

Yes. Before dubbing you can pick a male or female AI voice, and Vaivox generates the audio in your language with the voice you chose.
