Create my agentTechnical courses FAQ
Does the agent answer about course authorization and diploma registration?
It answers exactly what you write in the Brain about authorization, registration and the professional council. It doesn't interpret rules on its own.
Does it close the enrollment by itself?
It organizes everything up to the door: course, class, price, payment method and documents recorded in the conversation. The final confirmation stays with the school office.
Can I notify people who were waiting for the next class?
Yes. Whoever asked becomes a contact in the CRM, and when the date is set you send the notice to the list.
Does it work for a school with in-person and hybrid courses?
Yes. You add both formats and the agent explains the difference based on what the student is looking for.
In what other fields does the CertuAI agent work?
In any business that serves customers on WhatsApp, because the Brain is written by you. These fields have a day-to-day closest to yours.
Where can I read more about CertuAI's WhatsApp agent?

In short
