A smart coach explains the ideas and nudges you when you are stuck. The engine studies your mistakes and adapts to your level. Spaced repetition locks the skill in — you grow game after game.
A personal opponent: it studies your games, plays at your strength and grows with you. It will not crush a beginner nor roll over for a strong player. White, black, or both sides.
Not just "the best move" — real strategy in plain words: what your move did, what the reply changed and what the plan is now. Like a coach at the board: threats first, development second.
Three levels of help: the principle → which piece to move → where and why. You learn to think, not to memorize moves. Square names in the text are clickable — see them right on the board.
Move accuracy, blunders and missed tactics — with an explanation of why the move failed and what was better. Eval graph, mistake navigation and a "play from here" sandbox.
Forks, pins, mates — levels for any rating. The system spots the themes you stumble on and brings them back right on schedule, so the skill stays for good.
Play rated blitz against real people, invite friends with a link, watch live games and cheer for players with coins.
Your personal coach: not engine lines, but living explanations — straight from a real game.
