Knowledge base

What is a knowledge base?

A knowledge base is a searchable library of articles, FAQs and how-to guides that helps customers find answers without contacting support. It also helps your support team work faster, because everything they need to answer a question lives in one place.

The good ones replace 30-50% of incoming tickets with self-service. The bad ones are graveyards of half-written articles nobody can find.

Internal vs external knowledge bases

• External (customer-facing). Lives on your website. Customers search it before they raise a ticket. Examples: help centers, FAQ pages, public documentation.
• Internal (team-facing). Lives in your help desk or wiki. Agents pull from it during a conversation. Often more detailed, with troubleshooting trees, escalation paths and exception cases.

The smart move is to keep them connected. The same source of truth, with internal-only sections agents can see.

What makes a good knowledge base

• Findable content. Search that actually returns the right article on the first try. AI-powered search is now table stakes.
• Structured by question, not by feature. Customers search how they think, not how your product is organized.
• Maintained, not just published. Articles get out of date faster than you'd think. Build review cycles in.
• Connected to support. When an agent answers a new question well, the answer should turn into an article. When the article is wrong, an agent should be able to flag it.

Knowledge base and AI

Modern AI agents and chatbots use the knowledge base as their training source. The cleaner and more current your articles, the better your bot performs. This means good knowledge base hygiene is now an SEO play, a self-service play, and an automation play, all at once.
