Two courses in this track each built half of what a real support chatbot needs. Build a RAG Knowledge Base in WordPress, Course 10, built the pipeline that makes an assistant’s answers true: chunking, embeddings, a custom storage table, cosine similarity search, and a grounded prompt. Build Front-End AI Chat & Conversational Experiences for WordPress Visitors, Course 11, built the surface a real anonymous visitor actually talks to: a widget, a protected REST endpoint, session handling, and basic escalation. Neither course, on its own, is a shippable product. This course is where they merge into one.
This course assumes you’ve completed both Course 10 and Course 11, or are at minimum
comfortable with their core patterns: AiClient::input()->generateEmbedding(), a
dbDelta()-managed chunk table, cosine similarity retrieval, and the
register_rest_route() plus transient-session pattern for anonymous visitors. It does not
re-teach either. It builds past them, into the parts a real deployment needs that a course
introducing the fundamentals reasonably leaves out: indexing WooCommerce products and
custom post types, not just blog posts, citing real, verifiable URLs instead of a bare
list of source titles, a genuine real-time human takeover so a support agent can step into
a live conversation, honest answers on multilingual support and voice input, lead capture
inside the chat flow itself, an admin-facing analytics dashboard, and a closing look at why
keeping all of this data in your own database is a real architectural advantage, not just
a technical detail.
By the end, you’ll have something you could actually hand to a client or ship as a product: a chatbot that answers from real indexed content across post types and products, proves its answers with links back to the actual source pages, lets a human take over mid-conversation without the visitor starting over, and stores every piece of it, content, embeddings, and conversation history, on infrastructure you control.
