GPT Desktop is a standalone desktop client built on Electron that wraps OpenAI's ChatGPT API to offer a native application experience on macOS, Windows, and Linux. It features an intuitive chat interface, automatic conversation syncing, exportable logs, and multiple conversation windows. Users can save custom prompts as templates, organize chat sessions by folders, and adjust themes and fonts. Keyboard shortcuts and system tray integration make switching between chats and invoking the app quick and easy. All data is stored locally for privacy and offline access to previous conversations.
