How it works
How do I build a knowledge base with KnowX?
Four steps, all in the WordPress admin you already know.
Install the theme
Add KnowX from Appearance > Themes. On first activation it creates a Knowledge Base page and sets it as your home page.
Create your topics
Each WordPress category is a topic, such as Getting Started or Billing.
Write articles as posts
Publish a post and pick its category. It shows up in Recent Articles on the home page and on its topic page.
Make it yours
Set the logo, colours, fonts, header and footer in the Customizer.
What you get
What is in the theme?
Everything below is in the free download.
Two knowledge base home pages
Layout One has a hero with search, a tile for each topic, popular and recent articles, and a support section. Layout Two lists every topic with its articles.
Breadcrumbs and a search bar
An optional sub-header shows where the reader is and lets them search. It uses the Yoast SEO breadcrumb trail when you have it on.
A login screen in your brand
Set the login logo, its link and the page title from the Customizer.
Sidebars and widgets
Left and right sidebars, a KnowX Categories widget and four footer widget areas.

WordPress as knowledge base softwareHonest comparison
Hosted knowledge base software or WordPress with KnowX?
Both are fair choices. Pick by what matters most to you.
Hosted knowledge base software | WordPress with KnowX | |
|---|---|---|
| Getting started quickly | Usually the faster start | You set up WordPress first |
| Monthly software fee | Yes, often per agent or per seat | None for the theme. You pay for hosting |
| Where your articles live | On the provider's platform | In your own WordPress database |
| Hosting and updates | The provider looks after them | You or your developer look after them |
| Voting, analytics, AI answers, ticketing | Often built in | Not in KnowX. Added with plugins if you need them |
| Changing the design and behaviour | Limited to what the provider allows | Changeable with the Customizer and code |

Common questions
Is KnowX really free?
Yes. It is a free theme on WordPress.org under the GPL v3 licence. You pay only for your own hosting and domain.
Do I need to know how to code?
No. You write articles as normal WordPress posts and change the design in the Customizer.
Is KnowX a block theme?
No. It is a classic theme. You customise it through the Customizer, menus and widgets, and write articles in the block editor.
What does it not do?
KnowX does not include article voting, search analytics, AI answers, a chatbot or ticketing. If you need one of those, you add a WordPress plugin for it.
Can you build the knowledge base for us?
Yes. Wbcom Designs, the team behind KnowX, takes on custom work. It starts with a discovery call.
