What PlumiBot does in a group chat

The part that is easy to miss is that it works per group and per person at the same time. A group sets the languages it publishes in, so a Taipei–Osaka–Vancouver family chat can carry three versions of every message. Separately, each member sets the language PlumiBot speaks to them in — menus, buttons and confirmations, in their own language, without changing anything for anyone else.

Not all of it is free, and it is worth knowing which half is which. Text translation, the two games, the digest and stats are on every plan, the free one included. Reading a voice note, a photo or a shared link runs a second, larger model before the translation even starts — a photo costs roughly thirty times what a line of text does — so those need a paid plan. The alternative would be charging people who only send text for the photos everyone else sends.
