What does a conversation handled by the AI look like?
Example conversation
Box AI agent
Customer: How do I book a trial class?
AI agent: Right here. In the morning I have your open time slots. I will confirm before the day.
Customer: Do I need experience to start?
AI agent: This is how the box welcomes people who have never trained: what you entered.
Is an AI agent or manual service better for CrossFit boxes?
The agent wins on repetitive tasks, and the person keeps winning on whatever takes judgment. With manual service someone at the box 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 |
|---|---|---|
| Message that arrives during a workout | The coach answers later, when they remember | Answered right away, without interrupting the class |
| Class times | Asked several times a day | Answered automatically, with the schedule you maintain |
| Trial class | Arranged by a stray message and sometimes forgotten | Booked in the conversation, with a confirmation before the day |
| Question from someone who has never trained | Explained again to each person, with the coach too out of breath to write | Answered the way the box welcomes beginners, with no jargon that scares people off |
| Prospect who disappeared after seeing the price | Stays in the conversation list and fades away | Becomes a contact in the CRM and gets an automatic follow-up |

Create my agentWhat needs to be ready before you turn the agent on at the box?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The class schedule by day of the week, separating open classes from beginner classes
- The plans by weekly frequency, with monthly and annual price and enrollment fee if there is one
- The trial class rule: whether it is free, what the person brings and at which times they can come
- The freeze and return policy, with the deadline, the cost and what happens to the annual plan
- A short glossary of the box's vocabulary, so people who have never trained understand the answer
Whether the agent can close a plan directly in the conversation or whether every enrollment goes through the coach after the trial class.
The most common mistake: Letting the agent answer in a formal office register. A box has its own way of talking, and a reply with “dear student” and a three-line sentence sounds like another company answering on your number. Read how to fix this.
Frequently asked questions from CrossFit boxes
Does the agent scale the day's workout for beginners?
No. Scaling, load and movement correction belong to the coach, inside the box. The agent handles schedule, plan, trial class and rules.
Can it explain the box's acronyms and vocabulary?
It knows what you write in the Brain. It is worth adding a short glossary, because people who have never trained stop asking when the answer comes full of internal terms.
Can I use it only for the trial class?
Yes. You decide what the agent covers and can leave only the trial class and the class schedule.
Does it answer about freezing and returning to a plan?
It answers the policy you write: how long a plan can be frozen, whether there is a cost and how the student comes back. Cases outside the rule it hands to 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?
These pages explain the same agent from another angle: how it works, price, common questions and comparisons between platforms.
In short
Class schedule, plans and beginner class answered without stopping the workout, with the trial class booked and the prospect saved in the CRM.
