ChessForge doesn't just show you blunders, it finds the PATTERNS in your mistakes across games. Paste any Chess.com/Lichess PGN and Stockfish analyses every move at depth 16, then groups your mistakes into patterns specific to YOU (hanging pieces, king safety, early queen moves, missed tactics) and builds a personalised training plan around your weaknesses. Your actual blunders become puzzles you can solve. Lessons are sorted by what YOU need most. Free plan available. Built by a teenager. 🚀♟️
