Description
JP343 Streaming Tracker logs your watch time on YouTube, Netflix, Crunchyroll, and any other site (via manual tracking). Built
for Japanese learners who want to keep track of their immersion hours.
The extension detects video playback and records sessions automatically. YouTube ads are excluded from your watch time. If your
browser crashes, the session is recovered on restart.
You can block YouTube channels from being tracked, edit session titles, and continue videos from the pending list. Sessions are
grouped by video.
No account needed. Your entries sync to JP343.com as a guest or with your account. Guest data can be claimed later when you
register.
How to use:
1. Play something on a supported site
2. The tracker starts on its own
3. Check your session in the extension popup
4. Visit JP343.com to sync
