WaniKani Notifier Chrome Extension Analysis

Listing positioning

The WaniKani Notifier is positioned as a simple, lightweight helper extension designed to alert users when their Kanji lessons and reviews are due. It emphasizes compliance with Chrome Extension Manifest V3, utilizing alarms instead of timers to balance API call frequency and system performance. The listing highlights its reliance on the WaniKani API v2 and features like local vacation mode to pause tracking.
