How to use this script

You need the tampermonkey chrome extension. You can install the userscript by hitting raw on the gist, and you'll be prompted to install it. Once installed while viewing a video, you can right click and then Tamper Monkey > anime-subtitle-downloader > Download subtitles (or just click on the tampermonkey icon and hit download subtitles from there, either way).

It does download all the subtitles for the show (normal japanese, hiragana, katakana, and english).

doesnt seem to list when right clicking on a video, does this still work?

I just tested it, and the menu correctly displayed under tampermonkey > animelon-subtitle-downloader > download subtitles

If that doesn't work, you can access the same functionality from the tampermonkey menu

Hi, actually I have the same issue. I downloaded Tampermonkey and the code but it doesn't seem to work :'(. Do you perhaps know what the issue could be? Thank you for the help!

I did notice the menu disappears after the first time you right click on it which I can look into. However, not working at all seems like it might be related to dev mode not being enabled, based on the 2nd screenshot.
