Esper: your agents, in the notch

Esper is a local macOS notch app by Quiet Engines that keeps Claude Code, Codex CLI, and Codex Desktop session status and plan usage in the Mac's physical notch. It is for Mac users who run coding agents: every agent session in one calm readout.

• No dock icon, no window, no account. Local.
• Resting glance in the notch; hover to reveal detail; peek for plan usage.
• Requires macOS 15 or later.
