Circuit: Productivity AI

AI that works with your iPhone — not just chat. Attach your calendar, run tasks via webhooks, dictate, and let the router pick the right model automatically.

CircuitAI is the AI assistant that picks the right model for every message — automatically.

Most AI apps lock you into one model. CircuitAI routes each prompt to the best option: Apple Intelligence on-device when it can answer instantly and privately, fast free cloud models for everyday questions, and frontier models like Claude, GPT and Gemini when a task truly needs them. You always get a great answer without thinking about which model to choose.

PRIVATE BY DESIGN • On-device first. Simple requests are handled by Apple Intelligence and never leave your iPhone. • When a message contains personal data, CircuitAI asks for your confirmation before anything is sent to the cloud. • No tracking. No ads. No selling your data.

BUILT FOR YOUR PHONE • Voice input — dictate on-device with Apple's speech recognition. • Attach context — calendar events, contacts, reminders, location and photos, only when you choose to. • Circuit Notes — a fast private notes space the assistant can read from and write to. • Shortcuts & Siri — trigger CircuitAI actions from anywhere on iOS.
