IAXT
A menu-bar flight recorder for AI coding agents. IAXT records what Claude Code, Cursor, Copilot, and Aider actually do on your Mac: every command, file change, install, and network call. Each action is attributed to the session that ran it, and reviewable after the session ends. It never blocks anything, and nothing leaves your machine.
