AI Engine – The Chatbot, AI Framework & MCP for WordPress vs Rapls AI Chatbot – Self-Hosted RAG & MCP Server

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. Core Modules 🤖 Chatbots Create intelligent chatbots with customizable themes, realtime audio, and multi-file support. 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. It also runs on your iPhone and iPad, through Workspace for WordPress. 🎨 Content & Media Generate content, translate text, create images and videos from prompts, and use Copilot in the WordPress editor to correct, enhance, translate, or rewrite text. 📝 AI Forms Build custom AI-powered forms that handle text, images, audio, or file uploads. Create advanced apps with conditional logic. 🧠 Knowledge & Embeddings Create embeddings and build knowledge bases from PDFs. Connect with Pinecone, Chroma, Qdrant, or OpenAI Vector Store for semantic search. 🔧 Function Calling Connect AI to WordPress functions, WooCommerce, appointments, or custom APIs. Let AI interact with your site’s data and services in real-time. 🛡️ Security & Moderation IP banning, word filtering, and content moderation to keep your AI interactions safe. 💡 Advisor AI-powered recommendations and insights to help you set up and optimize your WordPress site. 🔌 Developer Tools Internal APIs, REST endpoints, MCP support, and extensive hooks. Build AI-driven features, automate workflows, or create SaaS applications. 🖥️ Workspace (and its iOS app) A full-screen AI chat that lives in your WordPress admin, and now in your pocket too. 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.

APIs: Internal API for plugin integration REST API for external applications MCP (Model Context Protocol) support Function calling framework Integration: Works with SEO Engine, Social Engine, Code Engine Media File Renamer support Custom shortcodes and hooks Extensive WordPress filters Resources: Code Examples & Customization MCP (Model Context Protocol) AI Engine turns your WordPress site into an intelligent MCP server. 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.

Add an AI chatbot that answers visitors from your own content — and admits when it doesn’t know. Rapls AI Chatbot searches your posts, pages, and knowledge base first, then replies in natural language, in the visitor’s own language. With Grounded Answers Only mode, if your content has no answer, the bot says so instead of making something up. You can be live in about five minutes, for free, with no credit card. On first setup a guided “Start for free” panel hands you a free key from OpenRouter or the Google Gemini free tier, tests it, auto-selects a working model, and switches the chatbot on — no AI or API experience needed. Watch the setup, start to finish: No monthly SaaS fee — and no runaway bill. It runs on your own API key with no markup, and built-in Usage Control caps daily usage per visitor, so you can open the bot to the public without worrying about your API spend. A Monthly Cost Guard lets you set a hard budget, and Model Fallback keeps the bot answering on a lightweight model when your main model hits its quota. Conversations and keys stay on your own server. Built for site owners, agencies, and developers who want control over the model, the data, and the cost. Connect OpenAI, Anthropic Claude, Google Gemini, or OpenRouter, or any OpenAI-compatible endpoint such as Alibaba Tongyi Qwen (DashScope) — useful where OpenAI and Gemini are hard to reach — and switch anytime. Why site owners pick Rapls Free to try, fast to launch. Guided onboarding gets you from install to a working chatbot in minutes, with a no-credit-card OpenRouter or Gemini key. Grounded answers, or an honest “I don’t know.” RAG hybrid search grounds replies in your actual posts, pages, and knowledge base — and Grounded Answers Only mode keeps the bot from inventing answers your site doesn’t contain. Your bill can’t run away. Self-hosted and BYOK with no markup, plus per-visitor daily caps (Usage Control) so public traffic can’t drain your API budget. Replies that don’t sound like a robot. An optional AI-smell score reviews the bot’s Japanese replies for machine-sounding wording, so you can tune the tone. (Detection only — replies are never altered.) No lock-in. Switch between OpenAI, Claude, Gemini, and OpenRouter whenever you want. Speaks your visitors’ language. Automatic multi-language replies, so one bot serves an international audience. What it does Bring your own key: OpenAI, Anthropic Claude, Google Gemini, OpenRouter, or any OpenAI-compatible endpoint (Alibaba Qwen/DashScope, DeepSeek, Zhipu), switchable per site. Site learning: indexes your posts and pages so the bot answers from your content. Knowledge base: add Q&A or upload PDF/DOCX files, with priority over general answers. RAG hybrid search: combines keyword and semantic retrieval for grounded replies. Grounded Answers Only: an optional mode that makes the bot reply “I couldn’t find that” instead of inventing an answer your content doesn’t support. Web search: lets the bot pull current information when configured. MCP tools: exposes 5 Model Context Protocol tools, so agents such as Claude or ChatGPT can read and act on your site through conversation. Usage dashboard: tracks conversations, messages, and API cost. Usage Control: optional per-visitor daily caps so public traffic can’t run up your API bill. Unanswered Questions: records what the bot could not answer, with one-click “Add to knowledge” and an AI-drafted FAQ page. AI-smell score: an optional read-only score that flags machine-sounding wording in Japanese replies (detection only — replies are never altered). Industry starter templates: one click applies a ready-made system prompt and preset questions for hotels, shops, clinics, professional services, or company sites. Gutenberg block: drop the chatbot into any page or post. Deep-link auto-send: a ?raplsaich_q= URL opens the chatbot and sends the question automatically, so end-of-article “suggested questions” become one-click conversations. Turns visitor questions into content The bot doesn’t just answer — it tells you what your site is missing. Questions it could not answer from your content are recorded on the dashboard, one click turns them into a knowledge entry, and another click drafts an FAQ page from the last 30 days of real visitor questions. Answer gaps become content, content improves the bot, and the same pages work for SEO and AI search (LLMO). Self-hosted and private Conversations and keys stay on your own WordPress install. You are billed by your AI provider directly, so cost is transparent and there is no markup. Visitors can delete their own chat history from the widget (optional), and retention is configurable — GDPR-friendly by design. Free and Pro Free — not a trial. The free version is the full product: chatbot, site learning, knowledge base, RAG hybrid search, Grounded Answers Only, MCP server (5 tools), a usage dashboard (conversations, messages, and cost), and per-visitor daily caps. Run it forever at no cost on a free-tier key. Pro — for sites that run the bot as a business tool: Lead capture automation — collect contacts from conversations, with Google Sheets and Slack sync. Analytics — conversation, cost, and quality metrics at a glance. Usage Control suite — role-based limits, per-user monthly credits with auto-reset, and a usage-control dashboard to grant and track credits, so members and guests each get a fair share of your API budget. Extra MCP tools — product-search and analytics tools for AI agents, on top of the five in Free. Context & embedding controls — reprocess embeddings and shape the context retrieved for each reply. LINE integration (add-on) — connect the chatbot to LINE messaging, the dominant messenger in Japan. Up and running in about 5 minutes (free, no credit card) You do not need an API key or any AI experience to start. On first setup the plugin shows a “Start for free” panel with two no-credit-card paths: an OpenRouter free key or a Google Gemini free-tier key. Pick OpenRouter or Gemini. Click through to get a free key (about a minute) and paste it in. Press Test Connection — the key is validated and saved, a working free model is auto-selected, and the chatbot is switched on. That’s it. Each option states its data-handling trade-off up front (the Gemini free tier may use submitted content to improve Google’s models), so you choose with eyes open. You can switch to your own OpenAI, Claude, or Gemini key at any time.
