Field notes

The extension can sync move records from several Go servers, import SGF, or inspect a single video frame when move order is unavailable. Its example session combines KataGo's numerical evaluation with a written answer and three clickable candidate moves, navigable by arrow keys. The separate Play mode assigns Black to the user and White to KataGo, while review costs one credit after the game. Credit packs are one-time purchases and are described as non-expiring while the service operates.
