What is the best WhatsApp chatbot for low-cost clinics in Brazil?
The best WhatsApp chatbot for low-cost clinics in Brazil is the one that answers on the number the clinic already uses, with business rules written by you. An AI agent on WhatsApp for a low-cost clinic is CertuAI's automatic assistant. It answers the price of each specialty and each exam, explains whether service is first come, first served or by scheduled time, gives the address and hours and books the appointment, with the same answer for everyone.

A hundred messages a day asking about price: can the AI keep up?
Yes, and this is the case where the gain shows up fastest, because the questions repeat. The price list goes into the Brain once, with the name of each specialty and each exam the way the front desk says it, and the AI answers the right price instantly, at night, on Sunday and in the middle of the morning rush.
What protects quality is keeping it up to date. The AI repeats what is written, so a price increase that was not entered in the Brain becomes a wrong price said a hundred times a day. Agree that whoever changes the counter price list changes the text the same day.
"Which doctor should I book?": does the AI choose?
It does not choose. On a health account, the AI does not assess symptoms and does not say which specialty the person needs, even when the answer seems obvious. What it does is list what the clinic offers, say on which days each specialty has a doctor and offer to book.
If your clinic wants firmer triage than that, it has to be done by people. Write in the Brain the rule that sends the conversation to a person when someone describes a symptom, and say how long the team usually takes to reply. That way the person is not left standing inside a refusal.
What does the AI do with each low-cost clinic message?
| Patient message | What the AI does |
|---|---|
| "How much is the visit?" | Answers your price list, by specialty |
| "Is it first come, first served?" | Explains the service rule and the cutoff time |
| "I have a stomachache, which doctor?" | Does not recommend a specialty; lists what the clinic offers |
| "Do you take cards?" | Answers the payment methods you wrote |
| "I have chest pain and shortness of breath" | Tells them to call 192 (Brazil's emergency medical line) or go to the emergency room |
| "What is the address?" | Answers the address, landmark and hours of the location |

What changes in the clinic with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. Here are four everyday situations at the clinic before and after the CertuAI agent.
TodayTwo front-desk people doing nothing but answering prices on WhatsApp
With CertuAIThe AI answers price and hours and the team takes care of the waiting room
TodayDifferent prices quoted by different people
With CertuAIOne price list, answered the same way every time
TodayPatient arrives thinking it is by appointment and waits three hours
With CertuAIThe service rule is stated before they leave home
TodaySunday message answered on Monday afternoon
With CertuAIAnswered instantly, with the week's hours
What does a conversation handled by the AI look like?
Example conversation
Clinic AI agent
Customer: How much is a visit with the general practitioner?
AI agent: A visit with the general practitioner is your price.
Customer: Is it first come, first served or do I need to book?
AI agent: The service rule is what you set up.
Is an AI agent or manual service better for low-cost clinics?
The agent wins at repetitive tasks, and the person keeps winning at what takes judgment. Done manually, someone at the clinic has to stop what they are doing; with the CertuAI agent the reply goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| A hundred "how much does it cost" messages a day | Two front-desk people answering all day | Answered instantly, with the same price list |
| Different prices quoted by different people | Happens every week | One price list, in the Brain, answered the same way |
| Patient asking which specialty they need | The front desk takes a guess | The AI does not recommend a specialty; it lists what the clinic has and offers the appointment |
| First come, first served vs. scheduled time | Everyone understands it differently and the room fills up | The rule is stated in writing before the person leaves home |
| Message on Sunday night | Answered on Monday, when the person has already gone elsewhere | Answered instantly, with the price and Monday's hours |
What does the WhatsApp agent do for low-cost clinics?
It handles the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers patients your way, with your rules.
Price list answered with no queue
Consultation by specialty, exams, follow-up visits and packages, each with the price you set up. The AI does not round, does not negotiate and does not invent promotions.
Service rule explained in advance
First come, first served, ticket number, scheduled time or both: the person reads the rule before leaving home, and the waiting room stops arguing.
The AI never recommends a specialty
On a health account it does not say which doctor the person needs. It lists what the clinic offers and offers the appointment.
Address, hours and payment methods
The three questions that come up most after the price, answered in the same conversation, with what you wrote.
Alert to the person in charge of each department
If the clinic sets up departments, the AI classifies by topic and the server alerts the person in charge of that department, by message or email.
What questions do patients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday messages at the clinic no longer depend on you having your phone in hand.
How does the agent start answering at the clinic?
In three steps, on the same day. No installation, no code and no changing the number patients already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.
How much does an AI agent on WhatsApp cost for low-cost clinics?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business's Brain, the CRM, automatic follow-up and the AI assistants, which come with every paid plan. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No lock-in contract and no setup fee.
Get started now
Create my agentWhat needs to be ready before turning the agent on at the clinic?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The price list by specialty, exam and follow-up visit, the way the front desk quotes it today
- The service rule: first come, first served, ticket number, scheduled time, and the cutoff time for each day
- The address of each location, with a landmark and opening hours
- The payment methods and what the clinic accepts in installments
- The list of specialties offered, with the days each one has a doctor
- The sentence for someone who describes a symptom and asks which specialty to see
Whether the agent books directly on the calendar or only guides, with the front desk organizing the day's queue.
The most common mistake: Leaving the price list out of date in the Brain after a price increase. The AI repeats what is written, and an old price quoted a hundred times a day becomes an argument at the counter a hundred times a day. Read how to fix this.
Frequently asked questions from low-cost clinics
Does the AI answer the whole price list?
It answers what you set up, item by item. It does not round, does not create discounts and does not invent promotions that are not written down.
Does it point to the right specialty for a symptom?
No. On a health account the AI does not assess symptoms and does not say which doctor the person needs. It lists the clinic's specialties and offers the appointment.
Can it serve several locations on the same number?
The conversation is one, and the AI answers the address and hours of each location if you write them. An extra WhatsApp number, for a second line, costs R$ 200 (Brazilian reais) per month.
How many team members can use it?
The Start plan includes 5 people with role-based access and, from the sixth on, each one costs R$ 30 (Brazilian reais) per month. Pro includes 10 people and Max includes 25.
