IA aplicadaHow I train an AI with the real data of a business
An assistant without your business data is a search engine with good manners. The difference is not the model, it is what you give it to read.
There is a scene that repeats: someone asks an AI assistant to answer for their business and the result sounds fine but says nothing. It speaks in general terms, invents details and never mentions what actually happens inside the company. That is not a problem with the model. It is a problem with context.
An assistant is only as good as the information it can read. If it does not know your prices, your timelines, your products or your rules, it can only improvise. And AI is great at improvising, which is exactly what you do not want when a customer asks a real question.
My work starts before the model. I organise the data of the business: what exists, where it lives, how it updates and who is allowed to see it. Then I connect that information to the assistant so it answers with facts, not guesses. If the data is not there, the assistant says so instead of making it up.
Second comes judgement. A useful assistant knows the tone of the brand, knows how far it can decide and when it must hand the conversation to a person. It is not magic: it is design. It is clear rules put into words, plus an honest list of what the AI must not do.
When all of that is in place, the difference is obvious. The assistant stops sounding generic and starts sounding like the business. Not because it became smarter, but because it finally has something real to read.
