Need to split a club, class or company event into groups? The new Random Team Generator takes a whole list pasted from your group chat, and once you set the number of teams or the team size it makes random teams that never differ by more than one person, then picks a leader and treasurer for each.
You can pick people who must not end up together and keep them on different teams, and add your own roles such as note-taker. The result copies as one line per team, ready to paste into your group chat, and the list is used only in your browser and never sent anywhere.
