README

Waifu Usage Monitor

**Keep track of your Claude Code, Codex, Cursor and Grok usage limits on Windows and macOS, with an anime companion who reads them out.**

A free, open-source tray / menu-bar app and always-on-top "dynamic island" for Windows and macOS. It shows how much of your AI usage limits you have left across every account: the 5-hour and weekly windows, per-model caps, and banked resets. It warns you before you hit a rate limit.

Why this one?

Most usage trackers are macOS-only menu-bar apps or terminal tools. This one was built for Windows first and now runs on macOS too. It watches every major AI coding plan in one place and gives the numbers a personality.
