The listing shows the photo, but whoever wants to rent asks on WhatsApp what the photo doesn't tell them: how many people fit, whether dogs are allowed and how much the cleaning costs. The agent answers that at any hour and gathers the dates for you to confirm.

What is the best WhatsApp chatbot for vacation rentals in Brazil?
The best WhatsApp chatbot for vacation rentals in Brazil is the one that answers on the number the property already uses, with business rules written by you. An AI agent on WhatsApp for a vacation rental is an automatic assistant that answers how many people the property sleeps, minimum nights on holidays and in high season, cleaning fee, pet policy, how check-in works and the amount of the down payment. It does not check the listing channel's calendar: it collects the dates and number of guests and passes them to you to confirm.

What changes at the property 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 property, before and after the CertuAI agent.
TodayThe same question about how many people fit and how many beds there are comes back every day
With CertuAIThe agent answers the room and bed layout the way you wrote it
TodayThe cleaning fee only comes up at the end of the conversation and the guest gets annoyed
With CertuAIIt goes out with the nightly rate, in the first reply, with no surprise later
TodayA New Year's Eve question arrives in October and you answer when you remember
With CertuAIThe agent instantly answers the high-season minimum nights and saves the requested dates
TodayYou open the calendar in the middle of work to check a date and lose your train of thought
With CertuAIThe agent gathers dates, number of guests and pet request, and you confirm just once
What does a conversation handled by the AI look like?
Example conversation
Property's AI agent
Customer: Is the house free from the 27th to the 2nd?
AI agent: How many adults and children? I'll log the request for the 27th to the 2nd, and the date confirmation will follow.
Customer: Is there a cleaning fee on top of the nightly rate?
AI agent: Yes. The cleaning fee is your price, on top of the nightly rate.
Is an AI agent or manual service the better choice for vacation rentals?
The agent wins on tasks that repeat, and the person keeps winning on what takes judgment. Done manually, someone at the property 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 |
|---|---|---|
| Question about availability on a date | You stop what you're doing and open the calendar on your phone | The agent collects dates and number of guests and leaves the request ready for your confirmation |
| Minimum nights on holidays | Explained again to each person, and sometimes with a different number | Always the rule you wrote, by period of the year |
| Cleaning fee and extra charges | Remembered in the middle of the negotiation, when the guest has already done the math another way | Stated in the first reply, together with the nightly rate |
| Late-night message from someone comparing properties | Goes unanswered until you wake up | Answered right away, while the person is still deciding |
| Someone who asked the price and disappeared | Gets lost among other guests' conversations | Becomes a contact in the CRM with the dates they wanted, and gets an automatic follow-up |
What does the WhatsApp agent do for vacation rentals?
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 guests your way, with your rules.
Capacity and bed layout
How many bedrooms, how many double and single beds, and how many people the property really sleeps.
Nightly rate by period and minimum nights
Low season, high season and holidays, with the minimum nights you require for each.
Cleaning fee, security deposit and down payment
The extra amounts and the down payment percentage, stated together with the nightly rate so it doesn't turn into an argument later.
House rules
Pets, parties, noise, the condo's quiet hours and maximum number of visitors, written in your own words.
Collecting the booking request
Dates, number of adults and children and special requests logged in the conversation, ready for you to confirm.
What questions do guests send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday messages at the property no longer depend on you having your phone in hand.
How does the agent start answering at the property?
In three steps, on the same day. No installation, no code and no changing the number your guests 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 vacation rentals?
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 the agent, connect WhatsApp and see it working at the property.
Create my agentWhat needs to be ready before turning the agent on at the property?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The nightly rate table by period: low season, high season, long holiday weekends and New Year's Eve
- The minimum nights for each period, because it is the question that causes the most mismatches
- All the amounts that aren't the nightly rate: cleaning, security deposit, bed linen, extra guest
- The real capacity, counting double beds, single beds and sofa beds separately
- The house rules in writing: pets, parties, quiet hours and number of visitors
- How check-in and check-out work: front desk, key with the caretaker, keypad lock, times
Whether the agent already sends the down payment instructions when the guest accepts, or only collects the dates and calls you before any amount.
The most common mistake: Leaving the cleaning fee and the extra guest out of the first reply. The guest does the math with the bare nightly rate, gets the total later and the conversation dies there, even with the property free.
Frequently asked questions about vacation rentals
Does the agent check my Airbnb or Booking calendar?
No. CertuAI doesn't connect to listing channels. The agent answers rules, prices and capacity, collects the dates the guest wants and leaves it ready for you to check the calendar and confirm.
Then what is it for, if the booking already comes from the channel?
The channels stay as they are. The agent handles WhatsApp, which is where people who want to rent directly show up, and people who want to ask what the listing doesn't answer.
Does it work if I have more than one property?
Yes. You add each property to the Brain with its own capacity, prices and rules, and the agent answers according to what the guest is looking for.
Does it take the down payment?
It sends the payment instructions you wrote and logs the conversation. Checking that the payment arrived and releasing the date stays with you.
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 minimum nights, cleaning fee, how many people fit and down payment. Every conversation becomes a contact and a task in the CRM, with nobody typing.
