Anime Tracker Anilist by Peshi

Add the anime you're watching to your AniList account without leaving the episode. Click the toolbar icon and Anime Tracker reads the tab title, searches AniList for the match, and saves it to your Watching list with the episode number already filled in. From the popup you can bump progress with one click (auto completing a show on its last episode), set status and score, see a countdown to the next airing episode and how many aired episodes you're behind, and jump to a streaming site or the AniList page. It works on any site, and Crunchyroll, HIDIVE, Netflix, HiAnime, Zoro, 9anime, Gogoanime and AnimixPlay have dedicated title-cleanup rules, with generic rules handling everywhere else. No analytics, no tracking, and no server of its own: the tab title is read only when you click the icon and sent only to AniList, and your login token stays on your device.
