Everything you need to turn knowledge into stronger play
Play Against AI
Build your ideal opponent. Adjust the bot’s Elo, aggression, and opening repertoire, then play with an evaluation bar, hints, move ratings, and unlimited undo. When the game is over, review every move to see what you played well, where you went wrong, and what you should have played instead.
Fully Adjustable
Tactical Puzzles
Train exactly what you want to train. Explore puzzles from the Lichess database with powerful filters that let you narrow your practice by difficulty, theme, rating, and more. Stop solving random positions and start targeting your weaknesses.
