Command reference

Anything beginning with ? is a command. ?help lists them in the app, free of charge.

How commands work

Type a command as an ordinary message. Some are handled entirely on your device and cost nothing — ?help, ?balance, ?buy, ?model, ?git, ?anon, ?clear. The rest go to the server and are charged like any other reply.

Commands work in your own language: if the app is running in Spanish, the Spanish form of a command is recognized and folded back to its canonical name before it is sent.

Anything that is not a command is simply a question, answered by whichever model the conversation is set to.

The Help modal, listing every Nymbot command with a one-line description. — Every command, in the app, free to read.
