What changes at the school with an AI agent?

What changes is who answers first: the message no longer waits for you and is answered right away. These are four everyday situations at the school before and after the Certu Agent.

TodayIn November, opening questions come in all day and the school office answers in the order they arrive

With CertuAIEvery family gets an answer right away, with the opening for the grade they're looking for

TodayEach staff member quotes tuition and supplies with a slightly different number

With CertuAIThe same figure always goes out, the one you wrote

TodayDiscount requests are discussed at the front desk and nobody records them

With CertuAIThe agent records the request in the CRM and the administration decides with the history at hand

TodayRequests for a duplicate boleto (bank payment slip) get mixed in with people who want to enroll

What does a conversation handled by the AI look like?

Example conversation

The school's AI agent

Customer: Is there an opening for sixth grade next year?

AI agent: Here are the sixth grade openings:what you entered. Would you like to book a visit with the coordinator?

Customer: How much is the tuition and the enrollment fee?

AI agent: The tuition and enrollment fee are your price, and I'll tell you what's included along with it.

An example built from the questions on this page, not a real customer. The highlighted parts are what you write in the Brain: price, hours and your business's rules.

Is an AI agent or manual customer service better for private schools?

The agent wins on repeated tasks, and the person keeps winning on what takes judgment. With manual service someone at the school has to stop what they're doing; with the Certu Agent the answer goes out on its own and you step into the conversation when you want.

Aspect	The manual way	With the CertuAI agent
Enrollment and re-enrollment season	The front office answers in order of arrival and the queue grows	All families answered at the same time, with no queue
Openings by grade	Depends on someone opening the class list	Answered right away, with the grades you keep updated
Tuition, enrollment fee and supplies	Quoted from memory, with differences between staff members	Always the same figures, the ones you wrote
Scholarship or discount request	Discussed at the front desk, with no record at all	Recorded in the CRM with the family's details and taken to the administration to decide
Duplicate boleto (bank payment slip) and matters about enrolled students	Arrives mixed in with people who don't know the school yet	Separated and taken straight to the school office

Private school FAQ

Does the agent negotiate scholarships or discounts?

No. It only says what you authorized in writing, records the request with the family's details in the CRM and passes it to the administration to decide.

Does it answer about a student who already studies here?

No. Grades, incident reports, boletos and statements go to the school office. The agent serves people who are getting to know the school.

Can it organize a waitlist by grade?

Yes. When a grade is full, the agent records the contact and the grade in the CRM, and you reach out when a spot opens.

Does it work for a school with more than one campus?

Yes. You set it up by campus and the agent answers according to the address the family 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.
