About AutoDub

AutoDub is a free browser extension that dubs YouTube videos with AI voice in your chosen language, in sync with the video, and shows bilingual subtitles. It works in Chrome, Edge and other Chromium browsers, with a Firefox version on Firefox Add-ons. No account, no daily limit, no paywall.
