What it does
D4 Chess Club is a free AI chess trainer that teaches you why your moves are wrong — not just what the best move was. Play vs computer (1000–3200 Elo), get Stockfish move-by-move analysis, drill your weak tactical patterns, and train with an AI Socratic coach that asks questions instead of handing you answers. Free to start. No credit card. Built for club players who actually want to improve.
AI chess coaching, Stockfish analysis, and tactical drills — free to start. Play vs computer, analyze your games, and track real improvement.
D4Chess analyzes your game history, finds the patterns you keep missing, and drills you on exactly those — not generic tactics every app has. Adjustable from 1000 to 3200 Elo. Find the exact level that challenges without crushing you. Every move classified — excellent, inaccuracy, mistake, blunder — with the engine's best continuation. See attacks, hanging pieces, and king danger rendered on the board as you step through every move. Hundreds of tactical puzzles. Spaced repetition keeps you drilling the patterns you miss most. Board, notation, pieces, values, and center control — the foundation every improving player needs. Ranked by accuracy, XP, puzzle rating, and improvement trend. See…from d4chess.club

There's a separate model for each 100-point rating bucket from ~800 to 2200+, and the bots not only choose human-like moves but also burn clock time, play worse under time pressure, and blunder in human-like ways.
