Greasy Fork

I recommend to use the browser Extensions of this script, because they have some more Features:
Chrome: https://chrome.google.com/webstore/detail/mal-sync/kekjfbackdeiabghhcdklcdoekaanoel?hl=en
Firefox: https://addons.mozilla.org/en-US/firefox/addon/mal-sync/


MAL-Sync is a powerful userscript, which enables automatic episode tracking between MyAnimeList/Anilist/Kitsu and multiple anime streaming websites.
Makes it possible to use your MyAnimeList/Anilist/Kitsu anime/mangalist as a centralized bookmarks system for all supported pages

Does not work on greasemonkey, please use another userscript loader like violentmonkey or tampermonkey.
