What an AI agent is and how it is made: what it trains on (Mexico, 2026)

What an AI agent is and how it is made comes down to one word: training. There are three sources, and all three already exist inside your business — your past conversations, your property inventory, and a sketch of how you want the conversation to go. The first teaches it to sound like you. The second, to answer with real data. The third, to carry the prospect exactly as far as you decide.

Training is a different thing from programming: you hand it material and it learns the pattern. Which is why two agencies on the same platform end up with agents that talk differently, though neither wrote a single rule.

What do past conversations teach it?

Tone, the order of the questions, and the answers that already worked.

This is the source we recommend most, for a simple reason: your old chats are the only record of how your business actually speaks. They contain how you open, when you ask about budget, what you say when someone asks for a discount before seeing the property, how you close an appointment without pushing.

An agent trained on that material does not invent a personality. It copies yours, including the replies that took you three years to get right.

It also learns what no manual records: that “is it still available?” really means “what does it cost?”, or that the parking question is almost always followed by the pets question.

What do the properties add?

Hard data, so it answers without guessing.

You load your inventory — square metres, bedrooms, neighbourhood, price, whether it takes Infonavit financing, what the maintenance fee covers — and the agent stops giving generic replies. It sends the property sheet that matches what the prospect asked for, not an entire catalogue.

This is the difference between an agent that answers “we have several options in that area” and one that answers with three addresses, three prices, and the availability of each. The second conversation ends in a viewing; the first ends on read.

What if I have no past conversations?

Then it trains on a sketch, and it works just as well.

A sketch means writing down how you want the conversation to go: what it asks first, what it needs to know before booking, what it does when someone does not qualify, at what point it hands over to you. You do not need to write dialogue — you need to describe the path.

This is the normal starting point for an agency whose chats are spread across separate phones, or one still assembling its process. The agent goes live on that sketch, and from there the real conversations it holds become the material for the next round of training. In a month you have the first source you did not have.

Why do some agents sound robotic?

Because one of two things failed, and neither of them is “AI does not work”.

The first: the model is not good enough. Some models cannot hold a conversation with context, and it shows on the third or fourth reply, when it loses the thread of what you already told it.

The second, and the common one: the training was not right. You gave it too little context, or context about something else, so it cannot handle the situation in front of it and falls back on the safe, stiff answer.

An agent properly trained on your chats answers the way you would, because it literally learned from you. When it sounds like a robot, the fault is in the material, not the technology.

What does training cost?

Training is not charged separately. watsi’s plans start at $2,000 MXN per month, VAT included, and cover loading your properties, training on your conversations, and adjusting the sketch as many times as it takes.

What matters about the number is not the number: it is that a trained agent does what a generic bot does not — it qualifies financing, budget and timeline inside the conversation, sends the right property sheet, and writes the viewing into your calendar.
