Quotum is a Mac menu bar app that shows what's left on your AI coding accounts — Claude Code, Codex, Cursor, GitHub Copilot and 21 more — and how old each figure is. Alerts warn you when your pace will drain an account before it resets. For the tools you track, it reuses the sign-in they already keep on your Mac; it never rewrites another tool's credentials or poses as an official client. Public source of what it reads and sends: github.com/mashgundash/quotum-transparence. €4.99 once, macOS 26+.
