# How to build a knowledge base chatbot

A knowledge base chatbot turns help articles into a conversational support layer. It should retrieve the right article, answer directly, cite the source, and reveal where the knowledge base is missing or unclear.

## What is a knowledge base chatbot?

A knowledge base chatbot is an AI assistant connected to help center articles, docs, FAQs, policies, and product guides. Instead of showing a list of search results, it composes an answer from the best matching source content.

## Why citations matter

A support answer without a source is hard to trust and hard to debug. Citations let users keep reading and let the support team inspect whether the answer came from the correct article.

## How to prepare the knowledge base

Use descriptive headings, one topic per page, direct answers near the top, stable URLs, and clear policy wording. Remove duplicate or conflicting articles before expecting a chatbot to answer reliably.

## What to monitor after launch

Monitor unanswered questions, wrong citations, low-confidence answers, feedback, escalation reasons, and repeated search terms. These signals show which articles need rewriting or splitting.

## Where usedocs fits

usedocs crawls knowledge bases, answers with citations, records gaps, and helps teams convert repeated misses into a prioritized content backlog.

## FAQ

### Is a knowledge base chatbot the same as site search?

No. Search returns pages; a chatbot returns an answer and source links from those pages.

### Can it work with a small knowledge base?

Yes, but coverage will be limited. The bot should say when the answer is not in the available content.

### How often should a knowledge base chatbot sync?

Sync after product launches, pricing changes, policy updates, and any major support-content rewrite.

## Use usedocs for this
