No. CertuAI is based in Florianópolis and everything happens online. You build the agent in the browser and connect your number; nobody needs to come to you.
Does it work with an area code 19 number?
It works with the number you already use, from any area code. You connect by QR code or through Meta's official sign-up flow, and the number stays yours.

What happens when the agent doesn't know the answer?
It doesn't make things up. It tells the customer that a person will get back to them and sends you the conversation summary right away. You join the same conversation and the customer doesn't have to repeat anything.
Does it work alongside my team?

Is the price different in Campinas?
