How to train an AI with my company's data

Quick answer

How to build the Brain and train the agent?

There are 4 steps in CertuAI: Build the Brain, Talk to the agent, Fix what comes out inaccurate and Go live.

Step 1 of 4
Build the Brain
In the CertuAI builder, answer questions about services, prices, hours and rules, and paste in the material you already have, like your website, catalog and price list.
Step 2 of 4
Talk to the agent
Before you connect WhatsApp, ask the CertuAI agent the same questions your customers ask, to find out what's still missing.
Step 3 of 4
Fix what comes out inaccurate
Adjust the Brain wherever the answer didn't come out the way your business would say it. The fix applies to every conversation after that.
Step 4 of 4
Go live
Connect WhatsApp to CertuAI and keep updating the Brain whenever a price, schedule or rule changes. From then on the AI answers with your company's data, not generic information.

What information does the AI need to answer like your business?

What you would explain to an employee on their first day.

What you sell and for how much

Services, products, packages, prices and payment methods. It's the question that comes in most and the one that stalls customer service most.

Hours and availability

Days of operation, breaks, exceptions and how booking works in your case.

The customer service rules

What the AI can handle on its own, what has to go through you and what it should never promise.

The material that already exists

Website, catalog, menu, price list, replies you already send every day. None of it needs to be rewritten from scratch.

What's the difference between a generic AI and an AI trained on your business?

Before: Answers nicely, but doesn't know your price

After: Answers with the price you entered, the way you wrote it

Before: Guesses at hours and the exchange policy

After: Uses the rule you taught it, or hands the conversation to you

Before: You rewrite everything from scratch so it understands

After: You paste in your website, catalog and price list and it uses what already exists

Before: Every correction is lost in the next conversation

After: The correction goes into the Brain and applies to everyone

Why is the Brain the part that matters most?

AI models today are similar to each other. What separates good customer service from generic customer service is what the AI knows about the business it's serving.

The Brain is your business's knowledge base inside CertuAI. It's what makes the agent talk about your price, your deadline and your rule, instead of answering anything plausible.

And it's not a locked file. If the price changes, the hours change, or a new service comes in, you update it in a conversation and the agent answers differently from the next customer on.

How do I get started on CertuAI?

You build the agent, connect WhatsApp and see it working before any customer talks to it. CertuAI has no lock-in and no setup fee.

Frequently asked questions

The questions that come up before putting an agent live.

Do I need a ready-made database to train the AI?

No. You build the Brain in a conversation, answering questions about the business and pasting in the material that already exists, like your website, catalog or price list.

How long does training take?

The first version is ready in the same session. After that it's fine-tuning: you talk to the agent, see where it gets things wrong and fix them.

What happens when my price changes?

You update the Brain and the agent starts quoting the new price from the next conversation. There's nothing to redo.

Does the AI make up answers when it doesn't know?

It answers from what you taught it. Outside that, the expected path is to hold the conversation and call you, rather than risk information that isn't in the Brain.

Is my business's data available to other companies?

No. The Brain belongs to your business and only serves your business's conversations.

How much does it cost to train the AI in CertuAI?

Plans start at US$ 75 per month with Start. See the prices at certu.com.br/planos.
