Usage puts four AI balances in your Mac’s notch

Field notes

Usage presents provider balances as a small notch-resident status layer rather than a separate dashboard. The page describes three levels of detail: an always-on health bar, a hover strip covering four providers, and a click-expanded view with names, remaining tokens, and reset times. It supports macOS 14+, costs $8 once, and says keys are stored in the computer’s Keychain while balance checks run from that Mac.
