jp343 Track Your Japanese Immersion από jp343

jp343 is an immersion tracker for Japanese learners. It records your watch time automatically on YouTube, popular streaming sites and Spotify. Your progress is shown in a built-in dashboard with heatmap, streaks and session history.

The extension runs in the background while you watch. Ads are detected and excluded from your time. If your browser crashes, the session is recovered on restart. You can also track any other site manually with one click.

Features:
- Automatic tracking on supported streaming sites
- Block channels or titles you don't want tracked
- Edit session titles anytime
- All tracking data stays in your browser, no third-party analytics, no ads. Optional anonymous platform compatibility statistics help detect issues early.
- Optional account syncs your data exclusively to jp343.com via HTTPS

Built for Japanese immersion but works for any language. Whether you do AJATT, Refold or your own method, jp343 tracks your input hours so you can see your progress over time.
