Description

See which YouTube videos have captions and dubbed audio in your languages, right on the thumbnail. SubPeek puts a small label on every video thumbnail. The label shows the subtitle (caption) and dubbed audio languages the video has. Your languages are highlighted. How to use 1. Click the SubPeek icon in your toolbar and choose your languages. English is on by default. 2. Browse YouTube. Every thumbnail now shows its languages. 3. On search results and channel pages, turn on "Only show my languages" to hide videos that do not have your languages. Privacy SubPeek collects no data. No account, no servers, no tracking. It only talks to youtube.com, and your languages are saved in your browser. Good to know - Subtitles made automatically by YouTube are not counted. - Private or age-restricted videos get no label. SubPeek is an independent project, not affiliated with YouTube or Google. YouTube is a trademark of Google LLC. https://github.com/mpadlein/SubPeek
