YouTube Dual Subtitles

Show translated subtitles below YouTube captions with selectable languages and overlay position.

YouTube Dual Subtitles helps language learners and multilingual viewers read two subtitle lines at the same time on YouTube. When YouTube captions are visible, the extension reads the current caption text and displays a clean overlay with the original caption on top and a Google Translate result underneath. You can choose the source language, target language, and where the overlay appears on the video. YouTube Dual Subtitles is free and open source: https://github.com/bluezebra/youtube-lang-subtitles Features: - Dual subtitle overlay for YouTube videos with captions. - Searchable source language selector using the Google Translate language list, including Auto-detect. - Searchable target language selector using the Google Translate language list. - Overlay position selector: Bottom, Middle, or Top. - Toggle to enable or disable the extension. - In-memory translation caching while the page is open. The extension does not use analytics, ads, accounts, or developer-controlled servers. Caption text is sent to Google Translate only to provide the subtitle translation.
