Codenotch: macOS setup for agent usage monitoring

This Korean-language walkthrough presents Codenotch as an open source macOS app for checking coding agent usage from a notch at the edge of the screen. The speaker demonstrates a status panel for Claude Code and Codex, with remaining usage, reset timing and indications of whether an agent is running. The walkthrough focuses on monitoring several tools during parallel sessions.

Installation follows a download, double-click and drag-and-drop process. In Appearance settings, Always Show keeps the panel visible, while Show on Hover reveals it when the pointer reaches it. The Edge setting lets users place the panel at the top, bottom, left or right of the screen; the speaker prefers the right edge.

The Accounts tab detects agents already installed on the computer. The tutorial also explains how to enable entries manually when automatic detection misses them. The supplied description says Codenotch reads tools that are already logged in without requiring a separate login.

The speaker uses the light theme and demonstrates Solid Black for a darker panel. Switching to the transparent Liquid Glass appearance does not produce the expected result in the demonstration, which the speaker describes as a possible bug. The app lacks a Korean interface in this walkthrough, though the speaker finds the controls understandable without translation.
