What is the best WhatsApp chatbot for architects in Brazil?

The best WhatsApp chatbot for architects in Brazil is the one that answers on the number the firm already uses, with business rules written by you. An AI WhatsApp agent for architects is CertuAI's automatic attendant. It handles the one-hour conversation every prospect requires: property type, square footage, whether it is a renovation or new construction, timeline, and city. It explains the project stages and what is included your way, and books the briefing only with people who make sense for you.

What changes at the firm 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 firm before and after the CertuAI agent.

TodayA prospect asks "how much does a project cost?" and the conversation dies there

With CertuAIThe agent understands the type of work, explains its stages, and books the briefing meeting

What does a conversation handled by the AI look like?

Is an AI agent or manual customer service worth more for architects?

The agent wins on repeated tasks, and the person keeps winning on anything that takes judgment. With manual service, someone at the firm has to stop what they are doing; with the CertuAI agent, the reply goes out on its own and you step into the conversation whenever you want.

What questions do clients send on WhatsApp?

They are always the same, and the agent answers each one on its own. These everyday firm messages no longer depend on you having your phone in hand.

Frequently asked questions from architects

Project pricing depends on a lot of things. How does the agent answer?

It explains exactly that: it collects the variables, presents how you charge (per m², per scope), and turns the question into a meeting.

Does it receive floor plans and photos?

Yes. Files and photos arrive organized together with the project screening.

Can I keep my premium positioning?

Yes. The tone is yours: sober, technical, or welcoming. An immediate response reinforces professionalism, not the opposite.

How much does it cost?

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.

In short

The question about how much a project costs becomes a booked meeting: the agent collects area, scope, and timeline, and records everything in the CRM by billing stage.
