Chessigma vs ChessDataLab

Chessigma reviews your chess games, shows you where the points went, and turns your own mistakes into training. The app has five tabs: Home, Train, Coach, Games and Brain. FREE - Game review: import your games from Chess.com or Lichess by username, or paste a PGN or a game link. Every move is graded, the turning points are marked, and you see the better move and the evaluation graph. The Stockfish engine runs on your phone, so a review needs no account. - Puzzles: a daily puzzle to keep your streak, classic puzzles, and Woodpecker sets that repeat the same positions until the patterns stick. - Opening Trainer: learn opening courses line by line. The first lines of every course are free. - Brain Games: twelve short games with scores and leaderboards. Nine are built on chess, and three need no chess: a reaction time test, Queens and Memory Match. - Sparring: play the first bots on the sparring ladder. - A first look at your coach report, built from your recent online games. - One move explanation from the coach each day when you are signed in. Signing in is free and keeps your streak, puzzle rating, scores and progress on every device. SUPERCOACH Supercoach is the paid plan. It adds: - Coach chat: ask the AI coach about your games, your openings and your habits. - Your full player report in six chapters (Overview, Blunders, Clock, Tactics, Conversion, Openings), with a heatmap of your blind spots. - A daily plan of coached tasks picked from your own games. - Move explanations in every game review, and the option to play on from any position. - Blunder Shield and Blunder Training: drills built from the positions where you blundered. - Conversion Trainer: practice winning the games you were winning. - Every rival on the sparring ladder and every line of every opening course. Coach messages come from a monthly allowance. Coach answers are written by an AI model through a third-party service, and every answer has a Report button.
