Track your AI service usage and stay within your limits. THE PROBLEM AI services have usage quotas. You lose track. Limits hit at the worst time. WHY CHECKING MANUALLY ISN'T ENOUGH Each service has its own settings page โ€” but nobody opens five different apps to check usage one by one until it's too late. THE SOLUTION AIUsage tracks your AI service quotas โ€” Claude, Cursor, Antigravity, and more. See exactly how much you've used, how much is left, and when it resets. Simple. Visual. No more surprise limits. Support: steve_ham@icloud.com
