Analytics Cards Overview

The Analytics Cards provides you with powerful tools to assess and refine your repertoire. Each card focuses on a different analytical perspective — from identifying missing moves and engine inaccuracies to comparing your lines with master databases and online play. Together, they give you deep insight into how complete, strong, and practical your repertoire really is.

In the Builder, you have access to the following analytics cards:
