Pi is a counting bot with some cool features:
You earn saves by counting (1 save per 1000 numbers counted) - You start with 3.
The server itself can also gain saves and save a count if you're out of them. Every 10k numbers counted in a server = 1 server save.
You can disable or enable using your saves.
There is also a unique “run” command where 2 people can head to head for speed or length.
