Chess Overlay

Chess Overlay turns the Chess.com board into a visual learning workspace. Explore candidate moves, hidden threats, opening ideas, and engine lines without leaving the board. The overlay is visible only to you on your screen. It does not appear in screenshots, video recordings, or live streams on streaming platforms. - WHAT YOU CAN SEE • Legal moves and captures • Attack and defense counts • Tactical risks and vulnerable pieces • Pre-move candidate evaluations • Post-move grades, including Best, Excellent, Good, Inaccuracy, Mistake, and Blunder • Opening choices and numbered principal variations • Stockfish 18 and Lc0 engine analysis LEARN DIRECTLY ON THE BOARD Chess Overlay places visual feedback on the board you already know.
