99chess - A free chess coach that explains the plan, not just the move

99chess is a free chess trainer with an AI coach. It explains what your move did and what the plan is — in plain words, like a human coach. Adaptive engine opponent, game review, puzzles built from YOUR mistakes with spaced repetition. No install, no card.
