AI Usage

What it is

AI Usage is a GNOME Shell extension that puts your AI coding limits in the top bar. It shows how much of the 5-hour limit is left at a glance, and a menu with a tab per tool lists every limit the tool reports, when it resets, and a warning when your current pace would run out before the reset. It reads only what the official Codex, Claude Code and Antigravity CLIs report, so it needs no tokens, sends no telemetry and spends no quota.

Why I built it

I switch between Codex, Claude Code and Antigravity throughout the day and kept hitting limits without warning. Checking each CLI's usage command by hand was tedious, so I built a tiny always-visible indicator that tells me how much I have left and whether my pace will run out before the reset.
