Hey Data is a prompt framework and shortcut suite that replaces Siri with ChatGPT on Apple devices while keeping your data encrypted and stored locally.

Hey Data is a custom prompt framework and shortcut suite that lets you use AI models like ChatGPT instead of Siri on Apple devices. It runs on your iPhone or iPad through the built-in Shortcuts app, connecting to language models such as ChatGPT and GPT-4.
Privacy is a core part of the design. Your information and AI memories are encrypted by iCloud and stored on your Apple device. Memories are plain text files on your phone, so you can edit or delete them at any time. The framework also aims to prevent AI companies from using your requests to train their models.
Subscriptions include personalized customer support, updates, and new features from the creator. The shortcuts themselves are open-source and customizable, making them easy to share. The website also offers usage guides, which can be formatted into Notion pages for a small fee using GPT-4-32k. Separating the website from the shortcuts is a deliberate choice to give users transparency and control over their AI interactions.
Hey Data was developed by a single individual who wanted a better AI experience on Apple devices. The creator built a personalized prompt framework and a suite of shortcuts to improve how AI agents behave, with a focus on privacy, personalization, and user support through subscriptions.
Guides on using Hey Data are available on the website, and can be formatted into Notion pages for a small fee.
