Organize your docs. Help readers find them.
Structure a knowledge base for one product or many. Everything here is included in Free and Pro.
Products, sections and tags
Create unlimited products, sections and sub-sections. Choose single or multi-product mode, and group articles by theme with tags.
Blocks, shortcodes and widgets
Add listings with the Knowledge Base block or the [knowledgebase] shortcode. Eight blocks and four widgets cover listings, search, breadcrumbs, related articles and alerts.
Search and navigation
Live search suggestions appear as visitors type. Breadcrumbs show where readers are, an automatic table of contents is built from article headings, and related articles appear below each article.
Layouts and templates
Responsive grid layouts ship with the plugin. Style them with your own CSS, override templates in your theme, or use the block templates and patterns in a block theme.
Permalinks and content
Change the base slugs for articles, sections, products and tags. Write articles in the native editor, and add alert boxes with the [kbalert] shortcode or the Alerts block.
Performance and languages
Built-in caching keeps listings fast, with a separate cache for each language. WPML, Polylang and TranslatePress are supported, including translated products, sections and tags.
Setup and developers
Works on single sites and multisite networks. The Setup Wizard creates your structure and sample content, and settings export and import as JSON. Developers get hooks, a REST API and Abilities API tools for article search and section discovery.
Knowledge Base Pro
Gather feedback, guide readers and scale your docs
Knowledge Base Pro is a standalone plugin that includes every Free feature.
Find out what readers think
Readers rate articles with a binary or 5-star score. A low rating can ask a follow-up question, admins can get an email for each new rating, and admin lists can sort by Bayesian average.
Tracking and privacy
Choose a GDPR-friendly tracking mode, and use the suggested privacy policy text from the documentation.
Answer questions without leaving the page
A floating help widget gives live search and suggested articles on every page, and a contact form sends email notifications to you.
Labels, colors and suggestions
Set the widget labels and colors. Suggested articles are limited to published articles.
Build a three-column docs site
Documentation Layout Mode puts a sticky section tree on the left, the article in the center and an On this page outline on the right. It works on the knowledge base home, product and section archives, articles and search results.
Section Tree block and widget
The Section Tree is context-aware and highlights the current page. Use it as a block or a sidebar widget anywhere.
Control how the knowledge base looks
Choose from seven more layout styles, show the knowledge base as your homepage, and add a table of contents as a sidebar widget, a block or a floating panel.
Archive images
Featured images can appear on product and section archive pages.
Control URLs and caching
Build permalinks for articles, sections, tags and products from dynamic placeholders. Set the cache lifetime, clear the cache from the settings page, and flush permalinks from Settings.
Multilingual sites
With WPML, set the language URL format to Directory so custom permalink structures resolve for each language.
Manage content from GitHub or files
Sync Markdown documentation with a GitHub repository: a push updates the matching articles through a webhook, and changes can be pushed back. Export articles as a Markdown ZIP, SQL dump or XLSX file, and import a Markdown ZIP with taxonomy mapping.
Frontmatter and mapping
YAML frontmatter controls the slug, title, products and sections. Map repositories in Settings or on product terms.
Beta
Ask the Docs
Visitors ask a question in plain language and get a short answer drawn only from your published articles, with links to the sources. When the articles do not cover the question, it says so and points to the search results; an optional Content gaps report shows which questions went unanswered.
Turned on in Settings under AI (Beta). Requires WordPress 7.0+ and an AI provider connected under Settings, then Connectors. The provider bills each request.
Usage controls
Answers are cached, with daily and per-visitor limits, fallback providers and model comparison. The knowledgebase/ask ability and a draft-only knowledgebase/create-article ability are available to the WordPress Abilities API.
