AICat is a multiplatform client for ChatGPT designed for Apple's ecosystem, targeting developers and end-users who want a native SwiftUI experience across iOS, iPadOS, and macOS. It offers a feature-rich interface for interacting with OpenAI's models, including chat creation, custom parameters, message sharing, and iCloud synchronization.

How It Works

The application leverages SwiftUI for a declarative UI across Apple platforms. It handles network requests to the OpenAI API, utilizes local storage for chat and message persistence, and integrates in-app purchases for premium features. A key architectural choice is the inclusion of iCloud Sync for seamless data continuity across devices.
