Private by Design
Core conversations are processed on your iPhone and saved in the app’s local storage.
Eira for iPhone
Helpful AI conversations powered by Apple’s on-device Foundation Models. No account, external AI service, or API key required.
A quieter kind of AI
Eira keeps AI chat focused: open the app, ask what you need, and get a response from the model already on your device. No sign-up flow and no separate AI provider between you and the answer.
Why Eira
Core conversations are processed on your iPhone and saved in the app’s local storage.
Eira uses Apple’s Foundation Models framework instead of a third-party AI API.
Start a conversation without registering, signing in, or supplying an API key.
Built in Swift and SwiftUI, Eira is fast, responsive, and at home on iOS.
The app
Eira opens into a clean, native chat experience. Responses stream as they are generated, recent conversations stay close, and privacy controls remain easy to find.

Privacy
Core chat runs without an Eira-operated AI server. Your prompts and Eira’s responses remain in local app storage unless you choose to share or export them.

The core experience has no registration, profile, or sign-in requirement.
You do not need credentials for a third-party model provider.
Conversation history is saved within Eira on your iPhone and can be deleted in the app.
