Chess Analyzer is a cross‑platform chess application available on Web, iOS, and Android, developed with React Native for a unified experience. It allows players to upload or capture chess positions and instantly receive analysis, best‑move suggestions, and puzzle solutions. The backend features a custom‑trained AI model built on hundreds of chessboard images with varying piece configurations, combined with Stockfish, one of the world’s strongest chess engines, to deliver precise move recommendations.
Challenge
Chess players often struggle to analyze complex positions or verify puzzle solutions quickly, especially when using physical boards or screenshots. Existing apps required manual input of positions, which was time‑consuming and error‑prone. The client needed a solution that could automatically recognize chess pieces from images and provide instant, high‑accuracy analysis across devices.
Solution
We developed an app using React Native, ensuring seamless performance on web, iOS, and Android. The backend integrates a custom AI vision model trained on hundreds of labeled chessboard images to identify piece types and positions from photos. Once recognized, the system passes the position to Stockfish, which analyzes the board and suggests the best move or solution path. The app also includes live puzzle solving, move history visualization, and cloud synchronization, allowing users to access their analyses from any device.
Result
The app delivers instant, accurate analysis with over 95% recognition accuracy for board positions. Players can now upload a photo, receive AI‑powered insights within seconds, and continue their study or gameplay seamlessly across devices. The combination of image recognition and Stockfish analysis has transformed manual chess problem solving into a fully automated, intelligent experience.
