My Prompt Tester

On‑device data: Drafts and saved sets (prompt, instruction, response, and notes) are stored locally on your device.
iCloud sync (optional): If enabled, saved sets are synced via Apple’s iCloud using your Apple ID. Data is stored in your iCloud account and governed by Apple’s terms. The developer cannot access your iCloud content.

Draft and test prompts and app/assistant instructions for Apple Intelligence. Copy the prompt, instruction, and response together in one tap—or save them as a set. Saved sets sync with iCloud so you can access them on Mac, iPhone, and iPad.
