Bring AI Search to WordPress.

FE Search AI Pro is an add-on that extends the functionality of FE Search AI, our free WordPress plugin for adding AI search and an Advanced RAG chatbot to your site.

It includes a wide range of features designed for more robust, production-ready operations, such as flexible model selection, masking of configured forbidden words, opt-in support for Terms of Service and Privacy Policy agreements, API rate-limit settings, a built-in MCP-compatible server that enables AI agents to use AI search, and API token issuance for using AI search from mobile apps and headless environments.

While leveraging the capabilities of powerful AI models such as GPT and Claude, the AI search and chatbot in FE Search AI answer users’ questions based solely on information available on your website—unlike general-purpose services such as ChatGPT. Users can ask naturally, as if they were having a conversation, about anything they want to know regarding your site.

For site owners, FE Search AI helps visitors discover content more easily. Its hybrid search combines vector search with keyword search, making it possible to find information more accurately—including content that is difficult to locate with conventional keyword search alone.

A plugin that redefines the search performance WordPress needs in the AI era.

Unlike general-purpose AI chat services such as ChatGPT, FE Search AI is installed as a plugin on a WordPress website. When visitors ask a question through the chat interface, the plugin searches content within the site based on their request, and the AI generates an answer using the retrieved information. In other words, it serves as a guide for your WordPress site.

With conventional keyword search, visitors may not be able to find the information they need unless they already know the right keywords to use. FE Search AI helps guide users to relevant information more accurately than before—even when their questions are vague or phrased in natural language.

FE Search AI is available in both a Free edition and a Pro edition. The Free edition alone provides robust AI search and RAG chat functionality, making it easy to introduce on a wide range of websites.
Please note that usage fees for AI providers such as GPT, Claude, and Gemini are charged separately on a pay-as-you-go basis.

By using the Pro edition, you can also access advanced features and dedicated support, including:

• Flexible AI model selection based on your site’s goals and budget
• Support for specifying AI models in on-premises or local LLM environments in accordance with your security policies
• Prohibited-word settings
• Terms-of-use opt-in functionality
• Detailed logging and feedback features
• Integration with AI agents through MCP-compatible server functionality
• API token issuance for integration with headless environments and mobile applications

Discover FE Search AI, bringing next-generation search capabilities to WordPress in the age of AI.
