Most chess apps hand you a wall of mistakes. Chess Coach gives you one. It reads your recent games, finds the single highest-leverage weakness holding your rating back, shows you the evidence, and tracks whether it's actually getting better. HOW IT WORKS • Enter your Chess.com or Lichess username, or import a PGN • It reads every game, looking for the patterns that keep costing you points • You get one Focus Area, like "endgame conversion" or "hanging pieces under time", with a number behind it • Each Focus Area cites the games it came from, plus books, videos and articles to fix it TRACK REAL IMPROVEMENT Re-check the same weakness on your newer games and see the trend: improving, holding, or slipping. When it's solved, Chess Coach moves you on to the next thing. FREE, WITH NO ADS Analyses are unlimited and free. No ads, nothing to buy, no subscription. WHY IT'S DIFFERENT It reads the games you actually played, blitz, rapid or classical, not generic puzzles. And it won't bury you in forty findings you'll never act on. No account, no setup. Your games are sent securely to run the analysis and are never stored. Or bring your own Anthropic API key in Settings. Stop guessing what to work on. Fix one thing at a time.
