ChatGPT Siri is a Siri Shortcuts automation that replaces Siri's default voice assistant with ChatGPT API integration, enabling natural language conversations on Apple devices.
The tool solves the problem of Siri's limited conversational ability by routing voice input through the ChatGPT API instead. When you speak to Siri, the shortcut captures your question, sends it to OpenAI's API, and returns the response as spoken audio. This approach requires only an API key and the Shortcuts app—no separate application installation needed. The shortcut supports continuous multi-turn conversations, allowing you to maintain context across multiple exchanges within a single session.
Anyone adopting this tool should understand that it requires an active OpenAI API account with sufficient balance, since each query consumes API credits. The shortcut works across iPhone, iPad, Mac, HomePod, and CarPlay. The tool is best suited for users who want to replace Siri's voice assistant capabilities entirely and are comfortable managing an API key. Newer versions automatically save conversation logs to text files with timestamps and token usage statistics, stored in iCloud Drive for easy access and syncing. The most recent version adds support for sharing text to the shortcut via the Share Sheet on iOS and iPad, and through Quick Actions on Mac.
The project maintains multiple shortcut versions with incremental improvements. Development has progressed from basic continuous conversation support through additions of automatic note-saving, then file-based logging with detailed metadata, and finally integration with system share and quick action workflows. The README provides explicit setup requirements, API safety guidance, and troubleshooting steps for network access and iCloud Drive configuration.
