AI you can trust. As AI tools take on more freedom inside our machines, observability matters. IAXT is a macOS menu-bar utility that records what your AI coding tools (Claude Code, Cursor, Copilot, Aider) actually do: every command, file change and system interaction, attributed and reviewable after the session.
