// WHAT IS WP-RAG?
Most search tools return a list of links. WP-RAG gives users answers.
RAG stands for Retrieval-Augmented Generation — a technique where an AI model is given relevant context retrieved from your own content before it generates a response. Instead of relying solely on what a language model was trained on, RAG grounds the answer in your actual data. The result is accurate, source-cited responses that reflect your site, not generic internet knowledge.
RAG is a well-established pattern in the Python and data-science world, but it has rarely made its way into the PHP ecosystem — and almost never as a native WordPress plugin. Typically it requires separate infrastructure: a Python service, a vector database like Pinecone or Chroma, and glue code to connect everything to your CMS.
WP-RAG is different. The entire RAG pipeline — content ingestion, text chunking, vectorization, embedding storage, and similarity retrieval — runs entirely within WordPress and MariaDB. There is no Python runtime, no external vector store, and no additional services to manage. The only external call is to OpenAI to generate embeddings and chatbot responses.
Your WordPress content is the knowledge base. WP-RAG keeps it that way.
Install the plugin, index your content, and drop one shortcode onto any page or post:
// ADMIN DASHBOARD
Index your content from a single dashboard.
Monitor indexing progress, check your LLM provider status, and manage your content index — all from the familiar WordPress admin interface.
// HOW IT WORKS
Four steps. One shortcode.
1 — Install
Upload the provided zip (available soon), then activate it on your site.
2 — Configure
Add your OpenAI API key, choose your embedding model, and select which content types to index.
3 — Index
Run the indexer to process your pages, posts, and uploaded documents. Monitor progress from the dashboard.
4 — Deploy
Paste [hauswprag_chat] into any page, post, or widget area. The chatbot is live instantly.
// REQUIREMENTS
What your server needs to run WP-RAG.
WP-RAG uses MariaDB's native vector storage to keep your embeddings entirely within your existing WordPress database — no external vector store required.
Current requirements
- MariaDB 11.8.3 or higher — required for native vector column support used by the embeddings index.
- PHP 8.0 or higher — required for plugin compatibility and modern WordPress support.
- WordPress 6.0 or higher — recommended for full block editor and REST API support.
- OpenAI API key — used for generating embeddings and chatbot responses in the free version.
Pro version — coming soon: MySQL 9 vector support is on the Pro roadmap, enabling WP-RAG to work on hosts running MySQL 9 instead of MariaDB. Additional LLM providers including Claude / Anthropic and Ollama self-hosted models will also be available in Pro.
Why MariaDB?
MariaDB 11.8 introduced a first-class VECTOR column type and VEC_DISTANCE_EUCLIDEAN function that let WP-RAG store and query embeddings using SQL — keeping everything in one place with no additional infrastructure.
Not sure about your host?
Most managed WordPress hosts — including Kinsta, WP Engine, Cloudways with MariaDB stacks, and self-hosted setups — can be configured to meet these requirements. Contact us if you need help assessing compatibility.

// BEYOND THE PLUGIN
Need more than
a plugin can hold?
WP-RAG is our production RAG stack packaged for WordPress. The embedding pipeline, vector search, and retrieval logic are the same foundation we build into bespoke systems for enterprise clients.
If your organization needs RAG integrated into a system that isn't WordPress — private knowledge bases, multi-tenant architectures, or RAG pipelines connected to an existing CRM or intranet — that's a custom engagement. We've built both.
// When to talk to us
- ›Your knowledge base can't live in WordPress
- ›You need multi-tenant RAG across teams or clients
- ›Compliance or data residency rules out a hosted plugin
- ›RAG needs to connect to your CRM, ERP, or internal systems
- ›You need self-hosted or private LLM infrastructure
// LET'S WORK TOGETHER
Give your WordPress site
an AI assistant.
Install WP-RAG, index your content, add the shortcode, and let visitors ask questions instead of digging through pages and documents.
