What changes at the studio with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. Here are four everyday situations at the studio before and after the CertuAI agent.
TodayA prospect asks if there is room in the 6 p.m. class and the answer goes out at the end of the day
With CertuAIThe agent answers right away, with the schedule and the time slots that still have room
TodayThe explanation about frequency and price is repeated several times a day
With CertuAIAnswered automatically, with the table you defined
TodayA student skips without notice and the spot in the small class sits empty
With CertuAIThe confirmation the day before leaves time to reschedule or fit in someone else
TodayInitial assessment booked from memory between one workout and the next
With CertuAILogged in the conversation, with a reminder before the day
What does a conversation handled by the AI look like?
Example conversation
Studio AI agent
Customer: How many people train per class?
AI agent: Each class has what you entered training together, with the instructor's attention.
Customer: Can I try a workout before signing up?
AI agent: Yes. I have your open time slots for the assessment and trial workout. I will send you a reminder beforehand.
Is an AI agent or manual service better for functional training studios?
The agent wins on repetitive tasks, and the person keeps winning on what takes judgment. With manual service someone at the studio has to stop what they are doing; with the CertuAI agent the answer goes out on its own and you join the conversation when you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Question about an open time slot in a small class | Depends on someone checking each class's list | Answered right away, with the schedule you maintain |
| Price by weekly frequency | Explained again to every prospect | Answered automatically, with your table |
| Initial assessment | Booked between one workout and the next, with no record | Booked in the conversation, with a reminder beforehand |
| No-show in a class with few spots | Discovered at workout time, with the spot lost | Confirmation the day before opens room to reschedule |
| Prospect who asked the price and disappeared | Lost in the conversation list | Becomes a contact in the CRM and gets an automatic follow-up |

Class schedule
Which times exist and which still have room, as you update them.

Two, three or more times a week, with the prices you define.

Time confirmed in the conversation, with a reminder beforehand.
Confirmation and waitlist
A notice the day before and, when someone cancels, the agent offers the spot to whoever was waiting for that time.

They are always the same, and the agent answers each one on its own. These everyday studio messages no longer depend on you having your phone in hand.
How does the agent start answering at the studio?
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 the agent on at the studio?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The schedule by time slot with the maximum number of students each class holds
- The plans by weekly frequency, with the monthly price and what changes between two and three times
- How the initial assessment works: how long it takes, whether it is charged and whether it is credited toward the first monthly fee
- The no-show and rescheduling rule, and how much notice the student has to give
- The list of people who want to join each full time slot, to offer the spot when someone cancels
Whether the agent can fit a student into a full time slot when someone cancels or whether every fit-in goes through you.
The most common mistake: Leaving a full time slot with no waitlist. In a class with few spots, every cancellation is idle revenue, and with nobody waiting for the notice the spot simply does not get filled. Read how to fix this.
Frequently asked questions from functional training studios
Does the agent prescribe workouts?
No. It handles schedule, plans, assessment and calendar. Prescription stays with your professionals.
Does it help with empty spots in a small class?
The automatic confirmation the day before leaves time to reschedule, and whoever was waiting for that time gets a notice that it opened up.
Does it answer people returning after years away?
It answers with the welcome you write, how the first week works and what the assessment covers. Clearing or adapting the workout stays with the professional.
Can it remind the student of the day's workout?
Yes. You set up the reminder and the agent sends it before the class time.
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.
