TMSync Autor: sal

TMSync passively tracks what you watch and keeps your trackers up to date
automatically. No manual logging, no check-ins.

One watch, every tracker
TMSync records your progress to the trackers you connect, and it can update
several of them at once. Watch something a single time and every connected
tracker stays in sync automatically. Works with Trakt and AniList today, with
support for more on the way.

How it works
TMSync reads what is playing (title, season, and episode) from the page and
the video player, then records your progress for you. Coverage is defined by
lightweight, community-contributed "recipes." Not covered yet? Use the
built-in picker to add it in a few clicks.

More than tracking
• Rate and leave a private note on what you watched, right from the on-page
badge or the toolbar popup. One rating updates every connected tracker.
• Jump straight to any tracked item on its tracker.
• Handy shortcuts on your tracker pages take you back to where you watch.
• Works in Chrome and Firefox.

Privacy by design
There is no backend. Your viewing activity and login tokens stay in your
browser and are sent only to the trackers you connect, never to the developer
or anyone else. Access is requested only for the pages you explicitly enable,
never everything at install.
