Reference

Every Dota Buddy command.

Type these anywhere the bot is installed — a server channel, or a DM. Commands marked premium need a subscription; everything else is free.

Your stats

Free. Works in any server, or in a DM if you install the bot on your account.

/recent	Your last matches at a glance — hero, result, KDA, GPM.
/match	A full breakdown of one match.
/matches	Search your match history.
/status	Check whether someone is in a Dota 2 game right now.
