Chess Coach vs ChessLab

Chess Coach is your AI chess coach. Learn with guided chess courses, play bots or real people, solve chess puzzles, and understand every mistake in plain language. CHESS COURSES — LEARN IN ORDER Guided lessons across levels, from the rules to club play. You start with First Steps, learning how the pieces move, then move on to Beginner for tactics and openings, on to Intermediate for pawn structures, endgames and openings you learn from both sides, and on to Advanced for calculation and plans. Every lesson mixes theory, exercises and play on the board, and you don't move on until the position works. The first course is free. OPENING LAB Play your repertoire against an opponent who plays like a person, not like a flawless machine. Real positions and real mistakes — which is where an opening is actually learned. ENDGAME LAB The 100 chess endgames you must know, one by one: king and pawns, rook, queen, bishop and knight. Learn the technique with the position in front of you, then practise it with a different exercise every time — some you win, some you have to hold, just like in a real game. MIDDLEGAME LAB 25 pawn structures — the isolated queen's pawn, the Carlsbad, the hedgehog — each one explained the way a book would: what it is, who stands better and what each side should be trying. Then you name them in positions from real games, and the board marks the pawns that give it away. Every structure brings its own tactics, and a game you can play from it against a human-like opponent. DECISION TRAINER Read the position, calculate, decide: pick your move, play the line five moves ahead — yours and your opponent's — and ask why each move is played. PLAY BOTS — OFFLINE A roster of opponents from beginner all the way to grandmaster. Pick who you play, your colour and your pace: bullet, blitz, rapid, classical or no clock at all. Works without internet. PLAY CHESS ONLINE HU Chess, our own online play, with bullet, blitz, rapid and classical, your own rating and level-based matchmaking. Prefer Lichess? Connect your account and play there with your rating synced. YOUR AI CHESS COACH It reviews every move and tells you what happened: why it was strong, where it went wrong, what to play instead. It grades your moves and gives hints without spoiling the answer. And you can ask it anything about chess. Powered by Gemini, OpenAI, Claude, DeepSeek and Qwen, and it adapts to your level: — Beginner (800–1200): simple concepts and basic tactics — Intermediate (1200–1800): strategic ideas and positional play — Advanced (1800+): deep analysis and theory CHESS PUZZLES — STREAK, STORM & 30+ THEMES • Daily puzzle and a mix at your level • Streak: how many can you solve without missing? • Storm: three minutes against the clock • Over 30 themes: pin, fork, skewer, discovered attack, sacrifice, back-rank mate and more • Pawn, rook, bishop, knight and queen endgames • Your puzzle rating, so you can watch yourself improve OPENING TRAINER Hundreds of chess openings organized by ECO code, in three phases: learn with guided arrows, practise until you play it twice without errors, and master it through quizzes. Explore any opening in the Lichess database, with millions of games.

ChessLab is a complete chess companion for iPhone and iPad: play, analyse, train and experiment, with Stockfish built in, without ever leaving the app. OPPONENTS THAT PLAY LIKE HUMANS Nine characters played by Maia-3, a network trained on millions of human games: it does not look for the best move, it plays the one a human of that level would play, blunders included. Each has a style, a repertoire and a temperament, and a level set on the human scale. Or take on Stockfish, from beginner (~900 Elo) to maximum (~3190). Optional clock, hints, a warning before risky moves and an evaluation bar, all on demand. ANALYSE AND UNDERSTAND Every move is graded (inaccuracy, mistake, blunder, brilliant…), each player gets an accuracy score, and the app tells you why a move was bad. The Coach adds the share of players at your level who play it. At the end, it offers to turn your mistakes and missed mates into puzzles. Load a game by PGN, FEN, position editor or photo scanner. DAILY SESSION Every day, what to review: opening positions that are due, missed puzzles, an endgame. A streak of days and medals to keep you going. OPENINGS 58 hand-written openings (bilingual), checked against the engine: every move is explained, coloured arrows tie the board to the move list, and spaced repetition makes them stick. Import your own repertoires as PGN too. ENDGAMES 78 courses proven by endgame tablebases: no move taught gives up a win, no defence offered loses a draw. Plus free training, where any move that keeps the verdict is accepted. PUZZLES Over 100,000 problems from the Lichess database, filtered by level and theme, plus your own, drawn from your mistakes. Personal rating and “At my level”. VARIANTS AND MORE Chess960 and eleven variants against the computer (King of the Hill, Three-Check, Horde, Atomic, Crazyhouse, Duck Chess, Barricades…), each with its own analysis. Two-player mode, and a Laboratory to compare two Stockfish settings. IPHONE AND IPAD A large board with side-by-side panels on iPad, keyboard and trackpad, portrait and landscape. Fully bilingual, French and English. Optional iCloud sync, off by default. PRIVACY Offline by default: no ChessLab server, no analytics, no ads. Your games stay on your device.
