Frequently asked questions
Do I need an office in Rio de Janeiro to use it?
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 21 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.
Is the price different in Rio de Janeiro?
No. The Start plan costs US$ 75 per month in any city, with the agent, the Brain, the CRM and automatic follow-up for people who went quiet. There is no lock-in contract or setup fee.
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?
Yes. The agent handles the first contact and passes the conversation to the right person. Start includes 5 people, Pro 10 and Max 25.
Is the price different in Rio de Janeiro?
No. It's the same as in the rest of Brazil, with no capital-city pricing, no lock-in contract and no setup fee. What changes in Rio de Janeiro is what you teach the agent: the neighborhoods you serve, the hours and holidays like January 20 (Rio's city holiday).
Does CertuAI serve businesses outside Rio de Janeiro?
It serves all of Brazil, online. This page exists because Rio de Janeiro has 238,541 businesses, the 9th largest concentration among the 20 cities with their own page, and what changes from city to city is the hours, the holidays and the competition, never the product.
