Marks episodes and chapters on JustAnime as you watch or read them, wherever you are. JustAnime Sync keeps your anime and manga list up to date without you touching it. Watch or read like you normally do. When you're far enough into an episode or chapter, the extension marks it on your JustAnime account — and on any AniList or MyAnimeList account you've linked there. • Works on 200+ streaming and reading sites, from Netflix and Crunchyroll to MANGA Plus and VIZ • Every site has its own switch, and one switch pauses all of them • New sites arrive from the server, so you never wait for an update • Wrong title? Fix it from the page, and that page is never guessed again • Stopped halfway? It remembers where, so you can pick it back up • Add your own Plex, Jellyfin, Emby, Komga or Kavita — that address stays in your browser and is never sent to us Privacy: on a supported site the extension reads the page title, the address, how far along you are, and — where a site needs it — the text of the specific elements its rule points at. No other page content, no cookies, no browsing history. Nothing about what you watch leaves your browser until you connect an account. Before that, the extension only fetches the site list and sends an anonymous installation ping — a random id, the version and the browser name — so we can count active installs. The only server it talks to is justanime.me. You need a free JustAnime account: https://justanime.me
