What does a conversation handled by the AI look like?
Example conversation
Your business's AI agent
Customer: How much is in-person training?
AI agent: In-person is your price. What is your goal: weight loss, muscle gain, conditioning or rehabilitation?
Customer: Do you have early morning times?
AI agent: In the morning I have your open times. Want to book?
Is an AI agent or manual customer service better for personal trainers?
The agent wins on repeated tasks, and the person keeps winning on anything that takes judgment. With manual service, someone in your business 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 |
|---|---|---|
| A prospect who arrives in the middle of a session | Waits for you to finish the session and has already hired someone else | Answered right away, without you leaving the client you're training |
| Question about format and price | Explained again to every person: in-person, online, pair, coaching | Presented the way you defined, with the price of each format |
| New client's goal | Found out only in the first session, when the workout is already built | Collected beforehand, and the summary reaches you ready so you can build it right |
| End of the plan cycle | Goes by unnoticed and the client disappears without renewing | A rule calls the client back to renew a set number of days after they sign up |
| Someone who asked for a price and didn't reply | Stays in the history and nobody follows up again | A polite follow-up a few days later, without you having to remember |

Does the agent build workouts?

Does it reply while I'm in the middle of a session?
Yes, that's the point. The prospect is answered right away and you step in only to close.
How much does it cost?
Paid plans are for when your client base 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.
