How Do I Add a Help Center to My WordPress Site?
Add a help center to WordPress without plugins. Embed Kairoo's AI-powered widget with one line of code or link to your hosted help center.
TL;DR
Add a help center to WordPress by embedding Kairoo's widget script in your theme footer (takes 2 minutes). Your customers get AI-powered search and chat without a WordPress plugin, without database load, and without plugin conflicts.
Why not use a WordPress plugin?
WordPress knowledge base plugins (BetterDocs, Heroic KB, etc.) have downsides:
- They add database load to your WordPress hosting - They conflict with other plugins and page builders - They don't include AI chatbot functionality - They look like WordPress, not like a modern product - They require maintenance, updates, and security patches
A hosted help center like Kairoo runs on its own infrastructure. Your WordPress site stays fast. No plugin conflicts, no database bloat, no security surface.
How to add Kairoo to WordPress
Option 1: Widget only (2 minutes)
Add the widget script to your theme. Go to Appearance > Theme Editor > footer.php, and add before the closing </body> tag:
<script src="https://getkairoo.com/widget.js" data-help-center="your-slug"></script>
Or use a plugin like "Insert Headers and Footers" to add the script without editing theme files.
Option 2: Link to hosted help center
Add a "Help" or "Support" link in your navigation pointing to your Kairoo help center URL (help.yoursite.com or yoursite.getkairoo.com).
Option 3: Both
Most teams do both — the widget on every page for quick access, plus a full help center page linked from the footer.
Customization
Match the widget to your WordPress theme:
- Set your brand color in Kairoo's dashboard (Settings > Widget) - Position the button (bottom-left or bottom-right) - Add a custom welcome message - Enable/disable pre-chat form
For the full help center appearance, use Kairoo's custom CSS feature to match fonts and colors to your WordPress theme.

Frequently asked questions
Will the widget slow down my WordPress site?
No. The widget loads asynchronously (doesn't block page rendering) and is under 15KB. It has zero impact on your WordPress performance or Core Web Vitals.
Do I need WooCommerce for this?
No. Kairoo works with any WordPress site — WooCommerce stores, blogs, agency sites, membership sites. It's platform-agnostic.
