What to look for

An AI knowledge base is only as good as the articles behind it and what the AI does when they run out.

Can people read it?

A published help centre lets customers and search engines find answers without asking. The AI should answer from the same pages.

Does it show where answers came from?

Answers that link the articles they used can be checked, and corrected by editing the article.

What happens when it doesn’t know?

Ask each vendor whether the AI says so and hands over to a person, or answers anyway.

Who approves AI-written content?

If the AI drafts articles, check whether anything can go live without a person reading it first.

Does it show what’s missing?

The questions the AI couldn't answer are the articles to write next. Look for a tool that collects and ranks them.

Can you bring what you have?

Moving should keep your articles' addresses, or bookmarks break and search rankings reset.
