Scan games, analyze moves, improve faster. ChessCopilot turns any chess board — a real board, a screenshot, or your handwritten score sheet — into instant Stockfish analysis. Start with a 3-day free trial — full engine analysis on your own boards and games, no commitment. Cancel anytime before it ends. HOW IT WORKS • Scan a position — a photo of a real board or a screenshot from any app or video. ChessCopilot recognizes the pieces and runs Stockfish to find the best move and the top lines. • Scan a score sheet — photograph a handwritten or printed game; ChessCopilot reads the moves, checks them for legality, and lets you review the whole game move by move. • Play from here — continue any scanned position against the engine's suggestions, no re-scanning needed. WHAT YOU GET • Real engine analysis powered by Stockfish — best move, evaluation bar, and the top variations. • Whole-game review — accuracy, blunders, mistakes, and the key moments. • Save your games and export them as PGN. • Open any position or game in your favorite analysis site to dig deeper. • No ads, ever. No account or sign-in — your games stay on your device. WHO IT'S FOR Club and improving players who want fast, honest feedback: settle a "what's the best move here?", review the game you just played from your score sheet, or study a position you saw online. SUBSCRIPTION Start with a 3-day free trial, then keep ChessCopilot with an auto-renewing subscription. Each plan has a clearly stated daily scan allowance (never "unlimited" — every scan is a real AI request, so the limit is honest and shown up front): • Casual — 20 scans/day • Pro — 50 scans/day • Pro Yearly — 50 scans/day, best value A note on accuracy: recognition is AI-powered and isn't perfect — glance at the recognized board before trusting it, and fix any misread piece with a tap. Payment is charged to your Apple ID at the end of the 3-day free trial. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel anytime in your App Store settings.
