TechDelivery Chat indexes your WordPress website and allows visitors to ask questions about your website content.

Features included in the free version:

AI-powered chatbot
Semantic search using OpenAI embeddings
Incremental AJAX indexing
Clickable source references
Responsive chat widget
Adjustable chatbot title
Adjustable welcome message
Adjustable primary color
Fast indexing of changed content

The chatbot answers only from your own website content and provides links to the relevant pages.

Pro upgrade

TechDelivery Chat Pro is available as an optional upgrade and adds:

WooCommerce product and variation indexing
Product search mode in the chat widget
Product cards with image, price, and stock status
Conversation history for follow-up questions
Automatic product re-indexing when stock changes

WooCommerce is required for Pro product features. Product indexing, product search, product cards, and stock-related answers require WooCommerce to be installed and active. Without WooCommerce, Pro still adds conversation history and enhanced chat behaviour for website content, but not product features.

Upgrade from the plugin admin page after installing the free version.

External Services

This plugin connects to the OpenAI API to generate text embeddings and AI-generated responses.

The OpenAI service is required for the chatbot to index website content and answer visitor questions.

The plugin sends the following data to OpenAI:

During indexing, the content of published posts and pages is sent to the OpenAI Embeddings API to generate vector embeddings.
Every time a visitor submits a question through the chatbot, the question is sent to the OpenAI Chat Completions API.
Relevant indexed website content is included with the visitor’s question to generate an answer.

No data is transmitted until the site administrator enters a valid OpenAI API key and uses the indexing or chat features.

This service is provided by OpenAI.
