YumeDB Tracker — browser extension

~ the graph, watching with you

Track from
where you watch.

The extension detects the episode playing on your streaming site and syncs it to your YumeDB list — both ways, on every device you approve.

✓ one-click «mark seen» from an in-page HUD
✓ two-way sync — revocable per device
✓ local-first: works offline, pushes when connected

01 / what it does

multi-site detection: media session, JSON-LD, DOM and URL strategies — plus your own custom sites with a live probe editor
in-page HUD: a quiet card appears over the player: mark seen, fix the match, jump to the record
two-way sync: local-first storage that pushes to your account and pulls the freshest state — last write wins
device tokens: authorized from the web with your session; revocable anytime in settings → developer
episode notes: per-episode note + rating right after marking, if you want them

01 · detect

It sees the episode.

The card slides in over the player with the match already resolved — one click and the episode is history.

02 · track anywhere

Any anime, any tab.

Search, bind pages, step episodes and rate — straight from the toolbar, synced to your list.

03 · quiet by design

It never nags.

Ask, auto or manual — every prompt is optional and per-site. Your player, your rules.

The device token only grants read and write:self — it can update your lists, never your account. Content scripts never see the token, and everything works local-first if you prefer not to connect.
