# Quotum

> Quotum is an AI usage tracker for the Mac menu bar: it shows the remaining usage of Claude Code, Codex, Cursor and other AI coding tools, for several accounts, with the age of each measurement.

Quotum reads twenty-five tools: Claude, Codex, Devin Desktop (formerly Windsurf), Cursor, Warp, Codebuff, Augment, opencode, Grok, Grok Bot, GitHub Copilot, Kiro, Cline, Kimi Code, Kilo Code, Nous Portal, JetBrains AI, Factory Droid, Muse Code, Antigravity, Doubao, Alibaba Model Studio, Amp, Z.ai and MiniMax. For Antigravity, Doubao, Alibaba Model Studio and Amp it runs the tool's own command-line tool, read-only; for Z.ai and MiniMax it uses a key the user pastes, kept in Quotum's own Keychain item and sent only to that provider's quota server; for Muse Code, each measurement creates a key on the user's Meta account, at most every fifteen minutes. Each quota window gets its own line (for example Claude's five-hour session and its weekly limit), with the share used, the time it resets and how long ago it was measured. On a Claude or Codex account, Quotum also opens that account's own copy of the desktop app, opens claude.ai or chatgpt.com in its Chrome profile, and pins a terminal to it. It requires macOS 26 or later, is sold outside the Mac App Store by MASH MEDIA (France), and costs €4.99 once at its launch price, then €9.99, after a free fourteen-day trial on the first two lines of the panel. It is not affiliated with Anthropic, OpenAI or any of the tools it reads.
