What changes at the school with an AI agent?
What changes is who answers first: the message no longer waits for you and gets answered right away. These are four everyday school situations before and after the CertuAI agent.
TodayA mother asks the time of the kids' class and the instructor only sees the message after the last lesson
With CertuAIThe agent answers the schedule right away, with classes by age and level
TodayA trial lesson booked by phone and forgotten on the day
With CertuAIBooked in the conversation, with a confirmation the day before
TodayA student skips without notice and the class spot sits empty

What does a conversation handled by the AI look like?
Example conversation
School AI agent
Customer: Is there a class for a four-year-old?
AI agent: The kids' classes and openings are as follows: what you entered. Want to book a trial lesson?
Customer: Do I need a medical certificate to start?
AI agent: What the school requires to start: what you entered.
Is an AI agent or manual service better for swim schools?
The agent wins at repetitive tasks, and people keep winning at what takes judgment. With manual service, someone at the school has to stop what they are doing; with the CertuAI agent the answer goes out on its own and you step into the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Open time slots by class | Only the front desk knows, and they are not always there | Answered right away, with the schedule you maintain |
| Trial class | Booked by phone, with no confirmation | Scheduled and confirmed in the conversation itself |
| Question about classes by age and level | Depends on the instructor leaving the pool to answer | Answered automatically, with the classes you entered |
| Missed lessons | Discovered when the student does not show up | Confirmation the day before reduces surprises |
| Lesson rescheduling | Turns into back-and-forth messages during the day | Settled in one conversation, with the times that are left |

Open time slots during the week
The schedule you maintain, answered at any hour, without pulling anyone off the pool deck.
Booking a trial lesson
Time confirmed right in the conversation, with a reminder beforehand.
Lesson confirmation and rescheduling
The day before and the day of, with the alternative times left on the schedule.
Requirements and items needed
Swim cap, goggles, medical certificate and water temperature: what the school requires and what it provides, answered your way.
What questions do members send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday school messages no longer depend on you having your phone in hand.
How does the agent start answering customers at the school?
In three steps, the same day. No installation, no code and no changing the number members already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.

Create my agentWhat needs to be ready before turning on the agent at the school?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The full schedule by day of the week, with the class, age and level of each time slot
- How many students fit per instructor in each class, which is the real limit on openings
- The trial lesson rule: whether it is free, how many a student can take and what to bring
- The medical certificate requirement, which document works and how long it is valid
- Whether the pool is heated and covered, because that is the question that comes back most in winter
Whether the agent confirms the trial lesson on its own within the schedule or whether the front desk approves each slot first.
The most common mistake: Booking a trial lesson without confirming the day before. A swim lesson has a set time and a counted spot, and a student who does not show up leaves the class short at a time another family was waiting for. Read how to fix this.
Frequently asked questions from swim schools
Does the agent replace the instructor?
No. It handles the schedule, prices, booking and confirmation. Lessons and technical assessment stay with your instructors.
Does it help reduce no-shows?
The automatic confirmation the day before, with easy rescheduling, is the direct way to do that.
Does it answer questions about medical certificates and health restrictions?
It gives the requirement you wrote, such as which certificate the school asks for and how long it is valid. Judging whether a child can get in the water is up to the doctor and your team.
Can I control how full each class is?
The agent answers with the schedule you keep up to date and logs the requests in the CRM. Deciding who joins which class stays with you.
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
