These numbers show you where the problem is. They cannot show you what is actually causing it — that takes looking at the moves themselves.

AICoachess analyses every move, then writes you a personalised explanation of your game, adjusted to your level automatically. The two or three decisions that changed the result, why you made them, and what to practise next. It reads like a note from a coach who just watched you play, not a list of engine arrows.
