An1me.to Tracker
Extension Actions
Track your anime watching progress on an1me.to with cloud sync across all browsers
Never lose track of where you left off.
An1me.to Tracker automatically detects what you're watching, saves your progress, and syncs everything to the cloud so your watch history is always up to date across every device.
- Automatic Tracking: Episodes are marked complete when you hit 85% — no buttons, no forms. Leave early and your exact position is saved for next time.
- Cloud Sync: Sign in with Google and your data syncs instantly across all browsers via Firebase. Watch on one device, continue on another within seconds.
- Season & Movie Grouping: Multi-season anime are automatically grouped into one collapsible card. Naruto, Bleach, Attack on Titan, Demon Slayer, One Piece — all seasons together. Franchise movies grouped separately with poster art.
- Filler Detection: Pulls filler data from AnimeFillerList.com and tracks your canon and filler progress independently. Filler episodes are highlighted so you can choose to skip them.
- Resume Prompts: Return to an unfinished episode and a prompt asks if you want to jump back to exactly where you stopped.
- Privacy: Your data stays in your browser and syncs only to your own Firebase account. No third parties receive your watch history.
