Core features:

- Universal video dubbing — Even when a video is not covered by the extension’s built-in one-click support, YouTube Dubbing can intelligently detect the media source and guide you to download the video and upload it to our server for subtitle recognition. You will receive an email when processing is complete, then come back and watch.
- Subtitle Summary — Subtitle Summary is not limited to YouTube; any website supported by the extension can summarize subtitle content.
- Subtitle Editor — If the translation or dubbing still is not satisfactory, copy subtitles from Subtitle Editor to your preferred AI model for translation, then paste them back and save. After manually enabling “skip translation for same-language subtitles,” the extension can dub with your custom subtitles.
