How to Install on WordPress

ProductLift is not a WordPress plugin you install from the directory. It is a hosted service you embed with one line of code. This means zero database tables, no custom post types, and no performance overhead as your documentation grows.

  • Add the ProductLift JavaScript SDK to your page (one script tag)
  • Paste the iframe embed code into a Custom HTML block, or use an HTML widget in your page builder
  • Or host your knowledge base on a subdomain like help.yoursite.com and link from your WordPress menu
  • Works with Gutenberg, Elementor, Divi, and any page builder

This tool is literally a needle in a haystack. I was using Frill, and this doesn't even compare. The user interface, the way it lays out — so amazing. Also amazing support team!

Who Uses a Knowledge Base on WordPress

Plugin and Theme Developers

Your users need more than a readme.txt. Setup guides, troubleshooting articles, and configuration references all in one searchable place.

WooCommerce Store Owners

Shipping FAQs, return policies, and product guides organized by category. Analytics show which articles your customers read most.

Membership and LMS Sites

Onboarding docs, course support, and billing FAQs. A hosted knowledge base loads fast even on membership sites already running dozens of plugins.

Agencies Creating Client Portals

Centralized docs for common WordPress tasks: updating content, managing media, basic troubleshooting. Stop answering the same client questions.

Connected to Feedback and Roadmap

Connected to Feedback and Roadmap

Most WordPress knowledge base plugins are standalone documentation tools. ProductLift connects your knowledge base to your feedback board, roadmap, and changelog in one platform.

  • Turn common support questions into feature requests and track them
  • Knowledge base articles link to related feature requests
  • Changelog entries reference documentation for new features
  • One embed code on your WordPress site for complete product communication

Most WordPress knowledge base plugins are dumping grounds for articles nobody reads. The problem is not the content. It is discoverability and the database overhead that comes with traditional plugins.

ProductLift uses AI-powered search to help users find answers instantly, and stores everything outside your WordPress database so your site stays fast. That's why over 3,000 WordPress sites use ProductLift.

WordPress Knowledge Base Plugin FAQ

How do I add a knowledge base to my WordPress site?

Sign up for ProductLift and create your knowledge base. Write and organize your articles. Click Embed to get your code snippet. In WordPress, add a Custom HTML block, paste the code, and publish. Or host on a subdomain like help.yoursite.com.

Do I need to install a WordPress plugin?

No. ProductLift is hosted on its own servers and embedded via a small code snippet. There is nothing to install through the WordPress Plugins menu, no database tables created, and no custom post types registered.

How is this different from BetterDocs or Echo Knowledge Base?

BetterDocs and Echo Knowledge Base store everything in your WordPress database with custom post types and taxonomy tables. This works for small documentation sets but adds overhead as you grow. ProductLift is hosted externally, so your database stays clean and your site stays fast.

Will it slow down my WordPress site?

No. The embed loads asynchronously after your page content renders. Zero database queries on your WordPress server. This is the opposite of traditional KB plugins, which add queries on every page load.

Will it work with my theme and page builder?

Yes. The embed works inside any HTML block, so it is compatible with Gutenberg, Elementor, Divi, and any other page builder. It adapts to your theme automatically, and you can customize colors and fonts to match.

Does it support multiple languages?

Yes. ProductLift supports 22 languages. Create separate categories per language or use a single language. No need for additional translation plugins.

Can I restrict access to certain articles?

Yes. Create public and private knowledge base sections. Private articles require authentication and can be restricted to specific user groups. Useful for membership sites with different content tiers.

Is there a free trial?

Yes. 14-day free trial with full access, no credit card required. Plans start at $14/month per team member with AI features, analytics, and unlimited articles included.
