What is the best WhatsApp chatbot for rheumatologists in Brazil?
The best WhatsApp chatbot for rheumatologists in Brazil is the one that answers on the number the practice already uses, with business rules written by you. An AI agent on WhatsApp for a rheumatologist is CertuAI's automatic assistant. It answers about prices, accepted health insurance and the waiting list, lists the tests the patient needs to bring to the first visit, records requests for reports and statements for health insurance and never advises on medication or dosage.

| 1 hour | The second is the follow-up with people who stopped answering in a conversation: you choose the wait, from 1 hour to 720 hours, and how many attempts. |

"Can I take the injection with a fever?": does the AI answer?
It doesn't answer, and this is one of the places where CertuAI's automatic reply is strictest. Rheumatology counts as a health account by the practice's name, and in that mode the AI never recommends a medication, never calculates a dose, never says to skip, double or stop, and the limit still holds even if the person says they are a doctor or asks for just a quick tip.
What it does is say in one sentence that it doesn't advise on treatment there and offer two ways out: book an appointment or pass the question to the team. Write in the Brain who gets that question and how long you usually take to reply, so the AI can tell the patient without making up a deadline.
Does a patient who disappears for months come back on their own?
Not based on the treatment timeline. CertuAI has no automatic outreach by interval: nothing in the system looks for patients who haven't had an appointment in three months and sends them a message. If you read that somewhere, it is not what the code does.
There are two different things. The first is the reminder for an appointment already booked, which goes out 24 hours and 1 hour before by default and can go up to three alerts per appointment. The second is the follow-up with people who stopped answering in a conversation: you choose the wait, from 1 hour to 720 hours, and how many attempts. Both depend on a conversation or an appointment existing.
What does the AI do with each rheumatology message?
| Patient message | What the AI does |
|---|---|
| "What do I bring to the first visit?" | Sends your list, with old tests and medication boxes |
| "Can I stop my medication this week?" | Gives no advice; passes the question to the team |
| "I need the statement for my health insurance" | Records the request with a date and promises no deadline |
| "How long until I can get an appointment?" | Repeats the waiting-list rule you wrote |
| "My hands woke up stiff, is that normal?" | Doesn't evaluate symptoms; offers an appointment |
| "Do you accept my health insurance?" | Answers from the list you registered |

What changes in the practice 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 practice before and after the CertuAI agent.
TodayAn hour-long appointment wasted because the patient brought no tests at all
With CertuAIThe list of what to bring arrives in writing twice before the day
TodayA medication question answered by someone who can't answer it
With CertuAIThe AI never advises, and the question reaches you marked as clinical
TodayA request for a health insurance statement told in a voice message and forgotten
With CertuAIThe request is written in the patient's record, with a date
TodaySomeone who asked the price and vanished is never contacted again
With CertuAIThe automatic follow-up calls back anyone who stopped answering
What does a conversation handled by the AI look like?
Example conversation
Practice AI agent
Customer: Which tests do I need to bring to the first visit?
AI agent: The list is: old tests, boxes of the medications in use, referral and insurance card. The reminder the day before repeats it.
Customer: How much is the follow-up visit and for how many days is it valid?
AI agent: The follow-up costs your price and is valid for your window.
Is an AI agent or manual customer service better for rheumatologists?
The agent wins at repetitive tasks, and the person keeps winning at what takes judgment. Done manually, someone at the practice 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 |
|---|---|---|
| First visit without the old tests | The patient arrives with nothing and the visit is only half as useful | The list of what to bring goes in writing when booking and comes back in the reminder |
| "Can I take my medication with a fever?" | The front desk answers on their own or drops out | Gives no advice; passes the question to the team with your text |
| Request for a report for health insurance | Said in a voice message that gets lost in the conversation | Recorded with name, date and what was requested, waiting for your decision |
| Patient asking their position in the queue | Pulls the front desk away from their work several times a day | Answers with the waiting-list rule you wrote |
| Conversation that dies after the price | Nobody follows up again | Follows up once or twice, after the wait you choose between 1 and 720 hours |
What does the WhatsApp agent do for rheumatologists?
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.
List of what to bring to the first visit
Old tests, boxes of the medications in use, referral and insurance card. The agent sends your list when booking, and the reminder the day before repeats it.
Medication questions are never answered
Immunosuppressant with a fever, a missed dose, a late injection: on a health account the agent gives no advice on any of this, even when pressed, and offers to pass the question to the team.
Report and statement requests recorded
Anyone asking for a document for their health insurance or for work has the request written in the conversation and in their record, with a date. The agent doesn't promise a deadline you didn't give.
Waiting-list rule always answered the same way
How long it usually takes, who gets priority, what happens when a slot opens up. Written once, answered the same way every time.
Follow-up with people who dropped off midway
Someone who asked about the price and stopped answering gets a second message after the wait you choose, from 1 hour to 720 hours later.
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 practice no longer depend on you having your phone in hand.
How does the agent start answering at the practice?
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 rheumatologists?
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.

Create my agentWhat needs to be ready before you turn on the agent at the practice?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The exact list of what the patient brings to the first visit, including old tests and medication boxes
- The price and duration of the first visit and the follow-up, and for how many days the follow-up is valid
- The waiting-list rule: average wait, who gets priority and how extra slots work
- The policy on reports, statements and prescriptions: what you accept by message and what requires an appointment
- The list of accepted health insurance plans, with what requires a referral
- The sentence the agent uses for every medication question, and who it goes to
Whether the agent gives the waiting time over WhatsApp or whether that answer stays with the front desk.
The most common mistake: Writing "answer patient questions" and expecting the agent to separate what is clinical on its own. The line needs to come with examples of the phrases your patients use. Read how to fix this.
Rheumatologist FAQ
Does the agent answer questions about medication?
No. On a health account it never recommends a medication, a dose or pausing treatment, even if the person insists or says they are a health professional. It says so in one sentence and offers an appointment or the team.
Does it contact patients who need a follow-up in three months on its own?
CertuAI has no automatic outreach based on treatment timelines. What exists is the follow-up with people who stopped answering in a conversation and the reminder for an appointment already booked.
How does a request for a health insurance statement work?
It is written in the conversation and in the patient's record, with the date and what was requested. The decision and the deadline stay with you.
Can it be used with the calendar the clinic already has?
With Feegow, the AI sees the open slots and books. With another calendar, it takes down the request and the front desk confirms.
Other clinic questions CertuAI has answered
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
Answers about the waiting list, tests the patient needs to bring and reports for health insurance, without ever advising on medication. Every request is recorded in the CRM.
