ChessGPT: AI Chess Coach is an application developed by Wozlo, designed to assist users in improving their chess skills. The application uses advanced GPT AI to provide live feedback on the user's moves and also explains the rationale behind the AI's own moves. When playing chess against the AI, users have the freedom to make unlimited moves and have an undo option available. Thanks to the save feature, users can store up to 10 games. A special 'dark mode' feature transforms the visual aesthetic for comfort in low light settings. The app is free of advertisements, ensuring an uninterrupted game playing experience. It is available for iPhone, iPad, and iPod touch with iOS 15.0 or later. Access to an advanced GPT AI model and other premium features like more game saves and unlimited undos requires a monthly subscription to ChessGPT+, priced at $4.99. An internet connection is required to access all functionality. The developer emphasizes its commitment to user privacy, asserting it does not collect any personally identifiable information.
