AI Engine (by Meow Apps) is the broadest AI plugin in the WordPress ecosystem and the most installed on WordPress.org, with tens of thousands of active sites. You bring your own API key and it gives you a chatbot builder, a content generator inside the editor, image generation, and a developer playground.
What it does well
- Chatbots you can drop on any page, trained on your content.
- Content and images generated right inside WordPress.
- Model choice: OpenAI, Anthropic, Google Gemini and a dozen more providers.
- MCP support so external AI clients can talk to your site.
Best for people who want one flexible plugin covering chat, content and images without stitching several tools together.
