No signal required. Arcs uses the Apple hardware in front of you instead of sending the work to a cloud model.
Offline is not a reduced mode
The core transformation—from raw material to understanding and finished work—happens on your device. A plane, remote landscape or unreliable meeting-room network does not turn Arcs into a simple recorder.
Privacy and availability are the same architectural choice
On-device intelligence means your material does not need to leave your hardware to become useful. It also means the app is not waiting for a distant service to answer.
Your work and your life keep moving
Some of your clearest thinking happens when the world cannot reach you. Arcs was built for people whose minds, work and lives do not remain neatly at a desk.
