Mayer

Mayer is (probably) the longest running public Arknights bot, started just as a clock on a single server, now she's on over 1800 servers and has a bunch of features such as displaying in-game data, forwarding official news or even a tag calculator.

Check out all of her features with the /help command!

Self hosted, continuously developed&updated, I keep improving her bit by bit even if it takes a while
