How to train your AI chatbot well (knowledge base in practice)

An AI chatbot is only as good as the content behind it. "Training" here isn't machine-learning wizardry. It's giving the bot the right material, keeping it current, and closing the gaps it reveals. Here's how to do it well.

Start from your three most common questions

Don't boil the ocean. List the three questions your support hears most, and make sure each has a clear, findable answer somewhere in the bot's content. That covers a surprising share of real traffic on day one.

Add the right sources

Breezaro builds its knowledge from a few source types:

• Documents. Upload PDF, DOCX, TXT or MD: your FAQ, returns and shipping policy, terms, size guides.
• Your website. Point the crawler at your site and it indexes your pages automatically.
• A product feed. For e-shops, connect your catalog so the bot can answer about specific products and prices.

Cover the basics first (policies and FAQ), then widen.

Write content the bot can actually use

• One topic per section, with a clear heading. Retrieval works best when each answer lives in a focused passage.
• Be specific. "Returns within 14 days of delivery" beats "we have a flexible returns policy".
• Cut the fluff. Marketing adjectives don't answer questions; facts do.

Keep it fresh

Outdated prices or deadlines turn into wrong answers, the fastest way to lose trust. When your content changes, sync the source again. For websites you can schedule automatic refreshes so the bot keeps up without you having to remember.

Close the gaps

This is the highest-leverage habit. Read your conversations. The ones where the bot fell back or couldn't help are a free to-do list of missing content. Add the answer, and next time the bot handles that question on its own. In the meantime, an operator can take over.

Mind your page allowance

Sources count toward your plan's page limit. If a large site would exceed it, ingestion stops at the cap (and you're notified), so point the crawler at the pages that matter rather than your entire archive.

FAQ

Do I need to "train" it like a machine-learning model? No. You add content; the bot does the rest. Training here means curating good sources and keeping them current.

What can I upload? Documents (PDF, DOCX, TXT, MD), your website via crawl, and a product feed for e-shops.

How do I improve answers over time? Watch the conversations for questions the bot struggled with, then add the missing content. It's a steady loop, not a one-off.

What if my site is huge? Ingestion respects your plan's page allowance and stops at the cap. Prioritize policies, FAQ and key pages.

Good training isn't a one-time setup. It's a short, repeating loop: add content, watch the gaps, fill them. Do that and the bot quietly handles more every week.
