What is the best WhatsApp chatbot for NR courses in Brazil?
The best WhatsApp chatbot for NR courses in Brazil is the one that answers on the number the training center already uses, with the business rules written by you. An AI agent on WhatsApp for an NR training center (NR = Brazil's workplace safety standards) is an automatic assistant that answers which standards the center teaches, whether the class is open to the public or held at the company's site, how many participants fit, how long each certificate is valid and the price per participant, and collects the company's list for the quote.

What changes at the training center with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. These are four everyday situations at the training center before and after the Certu Agent.
TodayA safety technician asks for a quote for eight people and the answer goes out the next day

With CertuAIThe company is recorded in the CRM with the date, and you open the follow-up task whenever you want
TodayThe participant list arrives chopped up across several messages

What does a conversation handled by the AI look like?
Example conversation
The training center's AI agent
Customer: Do you run NR-35 for eight people at my job site?
AI agent: Send me the job site address and the date you need. Then I'll record each participant's name and details for the certificate.
Customer: How long is the certificate valid?
AI agent: The certificate is valid for what you entered.
Is an AI agent or manual customer service better for NR courses?
The agent wins on repeated tasks, and the person keeps winning on what takes judgment. With manual service someone at the training center has to stop what they're doing; with the Certu Agent the answer goes out on its own and you step into the conversation when you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Quote request by number of participants | Waits for the instructor to step out of the training room | Answered right away, with the price per participant you set |
| Open class or training at the company | Explained again with every contact | Explained on its own, with the minimum number of participants you wrote |
| Certificate validity and refresher training | Lost when nobody writes down the training date | Each company stays in the CRM with the date, and the follow-up task shows up for the team |
| Participant list | Arrives loose in messages and someone types it all again | Collected in the conversation itself and recorded on the company's contact |
| Order that arrives outside business hours | Sits there until the next morning | Answered right away and already recorded for your team |

Does the agent answer questions about what the standard requires?
It answers what you write in the Brain about course hours, validity and content. Interpreting the standard stays with your technical lead.

That's the most common case here. The agent collects the CNPJ (company tax ID), number of participants and address, and leaves the quote ready for your team to close.
Does it help with refresher training?
Yes. Each company is recorded in the CRM with the training date, and you schedule the follow-up before it expires.

No. You connect the number your customers already use by scanning a QR code.
In what other fields does the CertuAI agent work?
