## What is CircuitAI?

CircuitAI is a private AI assistant that runs entirely on your iPhone. Ask anything — unlimited and free — and your words never leave the device.

100% ON-DEVICE
• Powered by Apple's on-device Foundation Models. No account, no servers, no message limits.
• Works offline — on a plane, on the subway, anywhere.
• No subscription. No ads. No tracking. Nothing to sign up for.

PRIVATE BY DESIGN
• Your prompts are answered on your iPhone and never leave it.
• CircuitAI only reads your calendar, reminders, contacts, location or photos when you explicitly ask — and never creates or changes anything without your request.

APPLE INTELLIGENCE, IN ONE APP
• Chat with a fast on-device assistant.
• Writing Tools — proofread, rewrite and summarize right where you type.
• Image generation — describe it and get an illustration.
• Photo understanding — attach a photo and ask what's in it.
• Visual Intelligence — point your camera and choose "Ask CircuitAI about this".
• Scan text and QR codes with the camera.
• Voice input, read-aloud, and transcription of audio files.
• Circuit Notes — a private notes space the assistant can read from.
• Shortcuts & Siri — trigger CircuitAI from anywhere on iOS.

Apple Intelligence features require an Apple Intelligence–capable iPhone (iPhone 15 Pro or newer) running iOS 26.

Everything runs on-device. No cloud, no subscription, no catch.
