AI Engine – The Chatbot, AI Framework & MCP for WordPress vs PurePen AI – AI Content Generator with Claude, GPT-4o, Gemini & More

AI Engine connects WordPress with AI models. One install, stable connectors for every major AI provider: OpenAI, Anthropic, Google, Mistral, and more. Build intelligent chatbots, generate content, create AI forms, and automate tasks. All from your WordPress dashboard. Please make sure you read the disclaimer. For more information, check the official website of AI Engine. Quick Intro Hello! ☀️ I built AI Engine to bring OpenAI, Anthropic, and other AI models into WordPress. Create chatbots that understand your content, generate posts in your voice, translate instantly, create images, or build custom AI tools. For developers: internal APIs, REST endpoints, function calling, and MCP support. Build AI features, automate workflows, or create SaaS applications on WordPress. There is also a Workspace: a full-screen AI chat inside wp-admin, with every model you configured, and a free iOS app so you can keep working on your site from your phone. Details on workspace.press. Feeling overwhelmed? 🤪 Start simple: Create a chatbot. Then connect Claude Code, Claude, ChatGPT, or OpenClaw through MCP, giving AI direct access to your site. Desktop clients can connect via OAuth: users just paste the MCP URL, sign in to WordPress, and approve. No shared token to manage. Add SEO Engine and watch it manage SEO in ways you never imagined. You can even connect AI Engine to multiple WordPress sites and manage them all through conversation. You’ll be having a blast before you’ve explored everything. You’ll probably spot bits of AI Engine in plenty of other AI plugins, code and UI alike. Flattering, really… or fishy? 🤣 But only AI Engine keeps pushing forward with real care for its community, a drive toward perfection, and the patience to get the details right.

Features modular UI Builder, conversation memory, and MacOS-style components. 🖥️ Workspace (with a free iOS app) A full-screen AI chat inside your WordPress admin: every model you configured, conversation history and folders, a prompt library, image generation, web search, and hands-on access to your site through the MCP tools.

Every model you configured is one tap away, in the same conversation: start a thread on Claude, continue it on ChatGPT or Gemini, generate an image, search the web, then let it work on the site itself through the MCP tools, with an approval dialog before anything is changed. Workspace for WordPress brings all of it to your iPhone and iPad. You scan a QR code once to pair it with your site, no password typed on a phone keyboard, and the pairing is a revocable Application Password you can cut off at any time. Your conversations, folders and themes stay on your own site, and your API keys never leave it. The app is free, the plugin is free, and there is no markup on anything: you pay your AI providers directly, at their price. More about it on workspace.press.

AI agents like ChatGPT, Claude, Claude Code, and OpenClaw can connect directly, browse content, edit posts, manage media, and handle complex tasks through natural conversation. What AI Agents Can Do: Create and edit posts Moderate comments Install and manage plugins Customize themes Check SEO and analytics Manage media files Run SQL queries Manage WooCommerce products, orders, inventory, and customers Handle Polylang translations Setup Guides: General MCP Overview MCP with ChatGPT MCP with Claude MCP with Claude Code Plugin Integration: Other plugins add their features to the MCP system: SEO Engine – Let AI analyze and optimize your content, fix SEO issues, and manage meta data Social Engine – AI can schedule posts, manage social media, and create social content Code Engine – Give AI access to code snippets and custom functions AI Engine can also connect to external MCP servers, extending your chatbots with tools and services beyond WordPress. A note on safety and “full access”: AI Engine’s MCP tools are curated and permission-aware on purpose. They do not run arbitrary code, so your site stays safe even while an AI agent works on it. Some people have asked us to match tools like Novamira and give an AI agent full, unrestricted control of WordPress through arbitrary PHP execution. We will not add that to the official AI Engine plugin, because it is genuinely unsafe: it effectively turns your site into remote code execution. If you specifically want that Novamira-style power on a development or staging site, we made an optional companion plugin, AI Engine YOLO, which brings the same unrestricted PHP execution and file access to AI Engine’s MCP server. It is dangerous by design, switches itself off on production, and is offered on GitHub only. Please never run it on a live site. Pro Features AI Forms: Create dynamic forms that generate answers, images, or files using AI. Embeddings & Vector Databases: Build knowledge bases from your content and PDFs for semantic search. Content-Aware: Let AI use your post and page content as context for smarter responses. Function Calling: Connect AI to WordPress functions, WooCommerce, or any custom API. Cross-Site Chatbots: Embed your chatbots on external websites. Editor Assistant: An AI sidebar in the post editor that can read, rewrite, insert, and rearrange your content blocks through chained function calls. Realtime Audio: Voice-based conversations on OpenAI’s GA Realtime API, with the latest voice reasoning capabilities. Statistics & Usage Control: Track usage, set limits per role, and monitor costs. Extra MCP Tools: Adds plugin, theme, database, Polylang, and WooCommerce management to the MCP server. Priority Support: Get faster help from the Meow Apps team. Why AI Engine? Native to WordPress Built specifically for WordPress with seamless integration. No clunky interfaces, just native WordPress experience. Flexible & Powerful Built-in connectors for OpenAI, Anthropic, Google, xAI (Grok), Mistral, Perplexity, OpenRouter, Replicate, Azure (OpenAI), plus a Custom (OpenAI-compatible) connector for Ollama, LM Studio, vLLM, llama.cpp, LocalAI, or any self-hosted server. Use the models that work best for you. Google (Gemini) runs on the new Interactions API by default, bringing stateful conversations, streaming with a live event log, function calling, and built-in Google Search and Google Maps grounding, with the classic API kept as a one-click fallback. Developer Friendly Clean APIs, extensive hooks, and MCP support. Build custom AI features or entire SaaS applications on WordPress. Real MCP, for Real WordPress You may have heard of MCP Adapter, built by the WordPress team primarily for their WordPress.com hosting service. It’s essentially a thin layer on top of the REST API. AI Engine takes a different approach: its MCP tools are specifically crafted for AI agents, with rich context, smart defaults, and practical actions that go far beyond what a generic REST API wrapper can offer. And it works on any WordPress installation, regardless of your hosting provider. AI Engine also exposes its REST API as MCP tools if you want that, but the dedicated tools are where the real power is. Privacy First IP hashing, GDPR tools, secure file handling, and session-based tracking. You control your data. Constantly Evolving Weekly updates based on real user feedback. We listen, we improve. My Dream for AI I am excited about AI, but I believe we need to use it with intention and clarity. Social media showed us how powerful tools can reshape our lives in ways we never expected, sometimes for the better, sometimes not. I want to avoid repeating those mistakes. AI should help us remove the meaningless, tedious work or enhance the work we enjoy. Modern tools should give us more time for what truly matters: spending beautiful moments with the people we love! 💕 Disclaimer AI Engine is a plugin that helps you to connect your websites to AI services.
