The key is kept in your device's Keychain, and only the study topic and the day's title and description are sent to OpenAI under your own account - never your notes.

AI-generated content can contain mistakes. Double-check important facts with trusted sources. Apple Intelligence requires a compatible device with Apple Intelligence turned on. Without it, you can use your own OpenAI API key.

Pre-made conversation topics for every level make jumping in a breeze. - Fully Open Source. - No accounts required. - Bring Your Own Keys: Plug in your own API key from OpenAI, Anthropic, or any compatible provider. You pick the model and pay only for what you use. Your conversations stay between you and whichever API provider you configure. - Voice I/O: Uses iOS's built in voice recognition and speech to text for free, on-device voice I/O.
