What is the best WhatsApp chatbot for real estate developers in Brazil?
The best WhatsApp chatbot for real estate developers in Brazil is the one that answers on the number the developer already uses, with the business rules written by you. An AI agent on WhatsApp for a real estate developer is an automatic assistant that answers using the material registered for each development (location, floor plans, amenities and delivery date), qualifies the lead by unit type and when they plan to buy, books the visit to the sales office or model unit, and separates new buyers, partner brokers and customers with a signed contract.

What changes for the developer with an AI agent?
What changes is who replies first: the message no longer waits for you and is answered right away. These are four everyday situations at a real estate developer, before and after the Certu Agent.
TodayThe launch ad brings in more conversations than the sales desk can answer
With CertuAIEach lead gets the floor plan and location they asked for right away
TodayA visitor arrives at the sales office and nobody knows which unit type they are looking for
With CertuAIThe visit is booked with unit type, target price range and purchase timeline already noted
TodayA partner broker waits hours for an updated price list
With CertuAIReceives the partner material you registered and the contact of whoever runs the channel
TodayA buyer with a signed contract does not know who to ask about construction
With CertuAIThe agent answers with the progress update you registered and logs the request for the customer relations team
What does a conversation handled by the AI look like?
Example conversation
Real estate developer AI agent
Customer: When are the keys expected to be delivered?
AI agent: The expected delivery for this development is your date.
Customer: Is the model unit open on Sunday? I want to bring my wife
AI agent: The model unit is open your hours. Which day and time work for the visit?
Is an AI agent or manual service better for real estate developers?
The agent wins on repetitive tasks, and a person keeps winning where judgment is needed. With manual service, someone at the developer has to stop what they are doing; with the Certu Agent the reply goes out on its own and you step into the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Surge of messages during launch week | The sales desk answers whoever it can, and the rest go cold until the weekend | Every lead answered right away, with the floor plan and location of the right development |
| Partner broker asking for the price list and material | Goes into the same queue as the end buyer | Identified as a broker and served with the material and the path you defined for partners |
| Question about financing and using FGTS (Brazil's severance fund) | Each sales rep explains it differently | The agent answers only what you wrote and passes the simulation to the sales team |
| Buyer asking about construction progress | Writes to the salesperson, who is already on another launch | Separated from sales and sent to customer relations, with the latest progress update you registered |
| Lead who visited the model unit and did not come back | Depends on the broker remembering to follow up | Stays in the CRM with the unit type of interest and gets automatic follow-up |
What does the WhatsApp agent do for real estate developers?
It takes over the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers buyers your way, with your rules.
Entry for each development
Address, unit types, square footage, parking spaces, amenities, construction stage and delivery date, as you registered them.
Qualifying the prospect
Which development, which unit type, whether it is to live in or to invest, and how soon they plan to buy.
Visit to the sales office and model unit
Day and time agreed in the conversation and recorded on the contact, along with who will receive them.
Partner broker channel
The agent identifies the broker, sends the partner material you defined and records whose client was introduced.
Relationship with people who already bought
Questions about construction, installments and documents are separated from sales and passed to the responsible team.
What questions do buyers send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday messages at a real estate developer no longer depend on you having your phone in hand.
How does the agent start answering customers at the developer?
In three steps, on the same day. No installation, no code and no changing the number buyers 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 real estate developers?
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 developer?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- One entry per development: address, unit types, square footage, amenities, construction stage and delivery date
- What can be said about price and payment terms, and what always goes to the sales team
- Address and hours of the sales office and the model unit, and who is on duty each day
- The material and the rules for the partner broker channel
- Who answers buyers with a signed contract: construction, installments and paperwork
Whether the agent gives the starting price of units, worded the way you write it, or whether price is only discussed by the broker during the visit.
The most common mistake: Leaving the old delivery date in the Brain after the schedule changed. The agent repeats the registered date to every lead, and an outdated delivery date given in writing carries more weight than any brochure.
Frequently asked questions from real estate developers
Does the agent say which units are available?
It answers with what is registered, and the sales availability chart changes all the time. The safest approach is for the agent to talk about unit types and pass the exact availability to the sales team to confirm, instead of promising a unit that has already been reserved.
Does it simulate financing or installments?
No. The agent does not calculate financing or approve credit. It explains the general terms you wrote, collects what the team needs to run the simulation and books the conversation with sales.
How does it handle a partner broker who brings a client?
It identifies that this is a broker, sends the registered partner material and records the name of the introduced client and the date. The rule for who keeps the client relationship is yours, and when in doubt the decision goes to the channel manager.
Does it answer questions about the contract, the development registration or the specifications document?
It only sends the document you registered for that purpose. The agent does not interpret clauses or answer legal questions: it records the question and passes it to the responsible person.
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.
