Example conversation
Gym AI agent
Customer: Can I take a trial class?
AI agent: You can. I have your open times. I'll remind you the day before.
Customer: How much is the monthly plan?
AI agent: The monthly plan is your price. Want to compare it with the quarterly and the annual?
Is an AI agent or manual customer service better for gyms?
The agent wins on repeated tasks, and the person keeps winning on anything that takes judgment. With manual service, someone at the gym has to stop what they are doing; with the CertuAI agent, the reply goes out on its own and you step into the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Question about a plan's price | Answered when someone steps away from the front desk, and the person has already visited another gym | Answered right away, with the plans compared your way |
| Trial class booked | The person forgets and doesn't show up | Reminder the day before, which is exactly where people drop out |
| Class schedule | Each person at the front desk gives a different time | Always the right schedule, updated in one place |
| Member who stopped training | Disappears unnoticed until the cancellation arrives | Called back at the interval you set |
| Questions about freezing and canceling | Turns into a line at the front desk at peak hours | Rule explained in the conversation, without tying up the front desk |

Get started now
Create the agent and connect WhatsApp to see it working at your gym.
Create my agentWhat needs to be ready before turning the agent on at the gym?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- Plans, prices and what differs between them
- Enrollment, contract length and cancellation rules
- Class schedule and which classes have limited spots
- How the trial class works
- What requires a physical assessment first
Decide three things: whether the agent books the trial class on its own, whether it talks about price before the visit, and what it does with people who want to cancel.
The most common mistake: A cancellation rule that exists only in the owner's head. The agent promises what the contract doesn't allow. Read how to fix this.
Gym FAQ
Does the agent sell plans on its own, or only book the visit?
Your call. Most gyms prefer that it answers questions about plans, clears up doubts about contract length and cancellation, and brings the person in for a trial class, because the sale happens inside the gym. But it can close on its own if you want.
Does it handle people who want to cancel?
It answers with the rule you wrote down: notice period, penalty if any, and how to make it official. It's the conversation that most often goes unanswered, and the one that most often turns into a complaint when each attendant answers differently from the contract.
Does the agent close the enrollment on its own?
It takes the person as far as you want: it can book the visit to close in person or send the enrollment link.
How does it know who disappeared?
You set the contact schedule and feed in the list, and the agent handles the reactivation conversations.
Does it replace the gym's management system?
No need to replace it. The agent handles WhatsApp: sales, questions and reactivation. Your management system stays the same.
How much does it cost?
Paid plans give you more volume when demand grows.
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?
These pages explain the same agent from another angle: how it works, price, common questions and comparisons between platforms.
In short
Answers questions about plans, class schedules and enrollment rules, and books the trial class. Every conversation becomes a contact and a task in the CRM, with nobody typing.
