Enter a Chess.com or Lichess username and get a complete diagnostic in minutes. Opening deviations, mistake patterns, pawn structure performance, key games to review, and AI-generated coaching insights.
Pulls up to 300 recent games and analyzes style, pawn structures, development patterns, and endgame tendencies.
Compares every opening move against a master position database. Flags deviations with Stockfish assessments.
Stockfish analyzes 15 selected games to find game-losing mistakes, missed only moves, and critical moments.
Generates a coaching summary and opening report adapted to the student's rating level. Actionable, not generic.
Playing style classification, castling habits, game type performance, and calibrated strength/weakness flags. Pawn structure performance uses Flores Rios classifications to show exactly where a student struggles structurally.
Key Insights are generated from calibrated thresholds, not arbitrary cutoffs. A "weakness" flag means a genuine, statistically significant pattern.
Full repertoire tree as White and Black, with win rates per line. Every deviation from master practice is flagged with frequency, score, and a Stockfish evaluation.
The AI opening report uses position context from 3,500+ annotated positions to understand whether a deviation is a known gambit or a genuine mistake.
A selection algorithm picks 3-5 games that best cover the student's flagged weaknesses. Each game shows theme badges and clickable critical moments with eval changes.
Game-losing mistakes, missed only moves, and winning-to-losing swings are surfaced across all analyzed games with an interactive board and Stockfish evaluation.
