About Fractal

A private AI, built to stay on your device.

Conversations are designed to stay on the device, with no account layer or server-side chat history.

Fractal is made for the moments when you still want useful AI without relying on a connection. Attach photos, images and files so the assistant can reason over more than plain text.

A minimal SwiftUI interface keeps it direct, readable, and comfortable for everyday use.
