## Description

Something felt wrong about that game. CheckChess tells you whether the feeling holds up.<br><br>Paste a username from Chess.com or Lichess and get a 0-100 suspicion score, built from move accuracy, how often the player matches the engine&#39;s first choice, average centipawn loss, move-time patterns, and how all of it compares to typical play at their rating.<br><br>WHAT IT DOES<br>• Account scans — any Chess.com or Lichess username, scored from that player&#39;s public game history.<br>• OTB analysis — paste a PGN from a tournament or a club game and get the same treatment.<br>• Detailed reports — per-move accuracy, centipawn loss and engine-match rate, charted game by game, so you can see where a verdict comes from instead of taking a number on faith.<br>• Watchlist — keep an eye on accounts and get told when something changes.<br>• AI analyst (Premium) — ask follow-up questions about any report and get answers grounded in that specific analysis.<br><br>THE ENGINE RUNS ON YOUR PHONE<br>Stockfish works through the games on the device itself. The engine pass never goes to a server, and a PGN you paste never leaves your phone to be evaluated.<br><br>IT REFUSES TO GUESS<br>A verdict on eight moves is worthless, so CheckChess does not give one. Short games, engine-vs-engine games and thin samples are excluded and reported as such. The score compares a player against people of their own strength, not against a grandmaster.<br><br>WHAT CHECKCHESS IS NOT<br>The score is a statistical signal, not proof. It exists to inform your own judgement — not to be used as a public accusation against anyone.<br><br>FREE<br>• 5 account scans and 3 PGN analyses a month<br>• 1 watched account<br>• Summary reports<br><br>PREMIUM<br>• Unlimited account scans and PGN analyses<br>• Full reports: charts, flags, per-move breakdowns<br>• AI analyst: 30 messages a week on Weekly, 1200 a year on Yearly<br>• 10 watched accounts<br>• PRO badge on your profile<br><br>Premium is a subscription billed through the App Store or Google Play. Cancel anytime from your store account settings.<br><br>CheckChess is not affiliated with or endorsed by Chess.com or Lichess. Stockfish is used under the GNU GPL v3.
