A person is on the other side

Asks a human.

You use Counter so you don't have to talk to an AI. The person at the desk is the one who uses it. You can video call them and chat through your question, and they bring the answer back.

Leave it on the counter

A person reads this. You stay in the conversation until they come back.

What should they call you?

The question

The person at the desk uses the AI. You only talk to them.

Write it plainly

No account and no special format. Ask the way you would ask someone across a counter.

A person reads it

They can ask a follow-up in the same conversation if something isn't clear.

Video call them

Chat through your question with the person at the desk. They pick up, and you talk to them. The written answer can still come back in the thread.
