AIUsageBot
Keeps an eye on how much of your AI subscriptions you have left and pings you as the remaining amount drops.
Problem
If you pay for several AI tools, it's easy to run out of usage at a bad time or not know what's left.
Solution
It interviews you about which AI subscriptions to track and where the usage numbers live (apps or local command-line tools), then sends you the remaining percentage as it goes down.
