Quick answer
The usual way is retrieval: the AI searches your approved documents for the passages relevant to a question, then answers using only those passages. You don't normally need to train a new model. Accuracy depends on keeping documents current, limiting who can see what, and telling the AI to say when it doesn't know.
Why doesn't AI already know my business?
A language model learns from general material and knows nothing reliable about your prices, policies or products. If you ask it anyway, it may produce a confident answer that is wrong. Giving it your own information, at the moment it answers, is what makes it useful for business.
How does retrieval work?
- Your documents are split into small sections and indexed by meaning.
- When someone asks a question, the system finds the most relevant sections.
- Those sections are given to the AI along with the question.
- The AI answers from them and can point to its source.
This approach is often called retrieval-augmented generation, or RAG. Updating a document updates the answers, without any retraining.
How should you prepare your content?
- Start with the documents that answer your most common questions.
- Remove old versions, which are a major source of wrong answers.
- Give each policy or price one clear source of truth.
- Use clear headings, so that sections make sense on their own.
- Give each document an owner and a review date.
How do you keep answers accurate?
Build a test set of real questions with correct answers, and run it every time the system changes. Instruct the AI to say it doesn't know rather than guess, and show sources wherever possible. Then review real conversations to find gaps in your content.
What about confidential information?
A knowledge base must respect the same access rules as your company. Staff should not be able to reach salary files through an assistant, and a public chatbot must see only public content. Set permissions at the document level, keep personal data out unless it is truly needed, and check how your provider handles what you upload.
