CircuitAI: Private AI Chat
Unlimited private AI, offline
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Unlimited, private AI that runs entirely on your iPhone. No subscription, no cloud, no tracking — just ask.
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.

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.
