- Worth noticing
- The homepage describes a transposition-aware opening tree and says its curated database covers 11 million rated games.
Field notes
The described analysis workspace keeps games and studies in separate tabs, with folders for organising material and autosaving for cloud studies. The homepage says a whole library can also be saved locally as PGN, and that individual studies can be shared with a coach, teammate, or student. Its worked examples distinguish practical game results from engine evaluations.
