AI summary of the plugin's readme

It connects WordPress to AI providers (OpenAI, Anthropic, Google, Mistral, and others) and exposes those capabilities through chatbots, AI forms, function calling, and an MCP server so AI agents can interact with the site.

Customizable chatbots with themes
Realtime audio conversations
Copilot editor assistant for text
AI Forms with conditional logic
Embeddings and knowledge bases from PDFs
Vector database integration (Pinecone, Chroma, Qdrant)
Function calling to WooCommerce and APIs
MCP server for AI agents

Frequently Asked Questions

Common questions about AI Engine - The Chatbot, AI Framework & MCP for WordPress

This error comes from OpenAI's API, not AI Engine. Set up billing limits in your OpenAI account. Caching plugins can sometimes store error responses, so clear your caches too.

AI Engine can be used by site owners, administrators, and visitors via chat widgets. To set query limits and prevent unlimited model runs, follow the Managing Limits guide.

AI models support many languages, but quality varies. There's no definitive list since models are constantly updated. Test your language in the AI Playground.

MCP (Model Context Protocol) exposes WordPress tools to AI agents. Learn how to enable the MCP endpoint, choose which tools to expose, and secure them. You can manage posts, comments, users, media, and more. Administrators get full access, and you can also let Editors connect with their own account for content only.

No. AI Engine is a complete, standalone solution: it talks to the providers directly and ships its own MCP server with more than fifty ready-to-use tools. The official AI plugin and its MCP Adapter are separate, experimental projects. You can keep them installed, but if both are active, let AI Engine manage the Connectors, or simply deactivate them to avoid confusion.

You can't completely block the model's built-in knowledge, but you can use smart prompts and embeddings to steer conversations toward your content. The chatbot doesn't appear or looks odd on my site Check the Common Issues guide for solutions to REST API problems, caching conflicts, nonce errors, and layout glitches.
