Yes. Zendesk has a knowledge base built on its help center, where Knowledge admins and permitted agents write and publish articles. Articles sit in sections, you can create up to 40,000 of them, and user segments control who can see what. Some features, such as the generative AI tools, need the Knowledge Professional or Enterprise add-on.
Who writes, who reads
Before you plan your first article, it's worth knowing who can do what. Knowledge admins can create new articles. Agents without that role can too, as long as they've been given management permissions. End users, meaning your customers, can't contribute articles, so there's no risk of public edits.
Permissions split into two kinds. View permissions decide who can read an article, and they apply to both internal and external users. Management permissions decide who can edit and publish, and they apply to internal users only. You can apply management permissions at the article level, so one sensitive policy page can have tighter control than the rest.
| Management permission option | Notes |
|---|---|
| Administrators | The default for new articles |
| Agents and admins | Opens editing to the wider team |
| Editors and Publishers | Enterprise plans only |
| Custom management permissions | Your own combination |
User segments keep internal articles internal
User segments define who can view, edit and publish. Two segments come built in, including signed-in users. That's how you keep internal guides for staff away from customers, or put a members-only section behind a login.
Writing and publishing an article
Every article has to live in a section, and at least one section must exist before you can create anything. Once you've got a section, you can create, edit, preview, save and publish articles, with formatting, links, images, tables, labels, tags and attachments.
The editor goes further than plain text. It supports callouts, accordions, tabs and markdown, plus an HTML source view, though Zendesk limits which HTML is allowed. Accordions and tabs are handy for long troubleshooting pages, because customers can jump to the bit that applies to them.
AI help with the writing
Generative AI tools can Expand, Simplify, Make more friendly or Make more formal. They're listed as part of Support with Knowledge Professional or Enterprise, so they're on the higher tiers rather than every account.
A starter structure for a small help centre
If you're starting from nothing, here's a simple shape I'd suggest. Begin with four sections: Getting started, Using the product, Orders and accounts, and Fixing common problems. Put your five most-asked questions into whichever section fits, and add a fifth section only when you've got enough articles to need it. Customers find answers faster in a short, obvious structure than in a long, clever one.
How big it can grow
You can create a maximum of 40,000 articles. That count excludes translations and archived articles, so a multilingual help centre doesn't eat into it faster. Very few small businesses will ever come close, so you won't need to plan around it.
Features that sit on the higher tiers
The Zendesk Help Center articles make clear that many knowledge base features sit behind the Knowledge add-on tiers. The generative AI tools and the fuller permissions model are listed under Knowledge Professional or Enterprise, and Editors and Publishers permissions are Enterprise only. So check what your plan includes before you promise your team a review-and-approve workflow.
Knowledge bases in two other help desks
Intercom publishes public articles through its Help Center. Articles must be in a collection to be visible and searchable, and its Fin AI Agent can use them to answer questions.

Freshdesk can run a multilingual knowledge base, with a portal that detects a customer's preferred language and colour-codes articles that need updates.

My take for a small support team
Yes, it has a solid knowledge base. Create three or four sections that match the questions customers ask most, write the top ten answers first, and use a signed-in segment for anything internal. Check your tier before relying on the AI tools or approval roles. And if you plan to feed your articles to an AI assistant later, my knowledge base prep checklist helps you structure them now.
