Where it works
- YouTube — works right after install.
- Netflix — optional. The extension asks for Netflix access only when you turn it on in the popup, so installing does not grant it.
- Not supported: YouTube Shorts, live streams and picture-in-picture. Videos without Korean subtitles are skipped.
What happens to your data
To create learning subtitles, this extension reads the subtitle text on the video page and sends it to our servers for linguistic analysis. We do not keep the subtitle text — only a hash of it and the analysis result.
We do not sell data, we do not show ads, and this website loads no third-party analytics or tracking scripts.
