An AI-powered WordPress chatbot that answers visitor questions using your own website content.

== Description ==

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

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

== 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.
