That's a maybe weird bot, with no main purpose. It's just that people sometimes uses more some features than others. The main stuff is :

• The /cooldowns command that aggregates your cooldowns from multiple game bots into a single image;
• A recreation of an official Discord bot (named "GDC game");
• The /votes command;
• The /getserver command (to get servers with Discord experiments); But there's also /viewlog (to log views), /settings hi (for help), and other things (sometimes old). The bot uses slash commands, it's easy to see the list of commands.
