Questions, answered
Is AutoDub really free?
Yes. The free tier dubs unlimited videos into 40+ languages using your browser's built-in voices, with no usage caps. Premium plans add ultra-natural neural voices and support for videos without captions.
Which browsers are supported?
Any Chromium browser — Google Chrome, Microsoft Edge, and Brave. Install it from the store in two clicks.
Does it work on every video?
It works best on videos that have captions (most tutorials, talks, and podcasts do). For videos without captions, our Premium plan transcribes the audio with AI first.
Do you store my videos or watch history?
No. Translation happens on the fly through secure cloud processing, and we don't store your video content or watch history.
Why do some free voices sound robotic?
The free tier uses your browser's built-in speech voices, which are functional but synthetic. Premium and Pro unlock natural neural voices from Azure and ElevenLabs.
How many languages can I dub into?
Over 40, including Spanish, French, German, Hindi, Japanese, Korean, Arabic, Chinese, and many more.
