== Frequently Asked Questions ==

### What is required to use AI Search for WordPress?
You need an OpenAI API key to use this plugin. You can get one from the [OpenAI website](https://openai.com/).

### How does this plugin work?
The plugin uses OpenAI’s `text-embedding-ada-002` model to generate embeddings for your posts. When users search, it matches the query embedding with post embeddings in the database for more relevant results.

### What happens if the OpenAI API fails?
The plugin handles API errors by logging them and reverting to the default search query.

== External Service ==

This plugin connects with Completions API from Open AI to get the embedding of the products. It also connects to the Embeddings endpoint.
