JamakFlix is a free Chrome add-on developed by JB Design that allows users to watch Netflix videos with Korean subtitles. This program is currently in beta version, with the service being activated as an urgent temporary update due to numerous requests. While the subtitles are available in multiple languages, the user interface is currently only available in Korean.

However, there are some known bugs and issues with JamakFlix. Firstly, the synchronization of subtitles may become delayed as the video progresses. Additionally, JamakFlix conflicts with Netflix's own subtitles, so users will need to disable the Netflix subtitles manually. When using the program in fullscreen mode, the subtitles may not be visible, so users are advised to press F11 instead of clicking the fullscreen icon.

It's important to note that JamakFlix operates on a limited budget as a free app, which means that there is a restriction on the number of subtitles the server can process in a day. Nevertheless, as a cloud-based service, the more users that utilize JamakFlix, the more accurate and convenient the subtitles will become.
