Play on Chess.com. Study deeper on Chessyi.
Chess.com is the default place to play, stream, and take lessons. Chessyi is not trying to replace that social board. It is built for deep study: 12+ heatmap overlays, local Stockfish, opening practice, and 1.9 million master games on one board.
The winning setup for many serious learners is both — export PGNs from Chess.com, then review with visualization tools Chess.com does not centre on.
| Feature | Chessyi | Chess.com |
|---|---|---|
| Primary job | Deep study & visualization | Play, social, lessons, review |
| Heatmap overlays | 12+ live layers | Eval bar / review graphics |

| Master library | 1.9M games bundled | Explorer / databases via platform |

| Best together | Import Chess.com PGNs | Export PGN after you play |
