What is the best WhatsApp chatbot for online courses in Brazil?
The best WhatsApp chatbot for online courses in Brazil is the one that answers on the number the course already uses, with the business rules written by you.

Example conversation
Course AI agent
Customer: How long do I have access to the lessons?
AI agent: Access to the lessons lasts your duration.
Customer: I bought yesterday and didn't get access
AI agent: That goes straight to the right person. Send me the purchase details and I'll pass it on now.
Is an AI agent or manual customer service better for online courses?
The agent wins at tasks that repeat, and a person keeps winning at what takes judgment. With manual service, someone at the course has to stop what they're 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 |
|---|---|---|
| Peak on sales opening day | The questions all arrive together and several go unanswered | Everyone answered at the same time, with no queue |
| Access question from someone who already bought | Gets mixed in with people who are still deciding | Separated right away and sent to your support team |
| Question about content and who the course is for | Answered from memory, in different words each time | One answer, the one you wrote |
| Payment method and PIX (Brazil's instant payment) | Explained one by one, person by person | Answered automatically, with what you accept |
| Student who stopped in the middle of the course | Nobody notices that they stopped | Stays in the CRM and gets the follow-up you schedule |

Create my agentOnline courses FAQ
Does the agent log in to the platform to release the student's access?
No. CertuAI doesn't connect to your course platform. The agent identifies the case, collects the details and passes it to your support team to solve.
Does it promise results to someone thinking about buying?
No. It answers content, format, access and price with what you wrote. Promises of results don't go in.
Can it handle the volume on launch day?
That's where it helps most. It answers everyone at the same time, including in the last hours, when questions arrive in a burst.
Does it work for someone who sells only through a link, with no team?
Yes. The agent plays the role of whoever would answer WhatsApp while you record a lesson or are away.
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.
