You can also use widget forms—the type is chosen when you set up the form (conversational vs widget). Submissions are stored locally, and each new entry can be delivered by email or Slack. ✅ Quick 3-Step AI Chatbot Setup Guided wizard launches after activation. Connect your AI provider, configure personality, add knowledge sources, and customize appearance—live in under 5 minutes. ✅ Advanced AI Chatbot RAG Technology Train on unlimited WordPress content using Retrieval-Augmented Generation. Supports pages, posts, custom post types, PDFs, text files, rich text input, Q&A entries, and webpage content fetched from URLs. Intelligent intent recognition retrieves the most relevant knowledge for accurate responses. Auto-sync keeps WordPress knowledge sources (pages, posts, custom post types) automatically up to date—no manual re-training needed when content changes. Knowledge Filtering lets you accurately filter and view which sources are available in your knowledge base. AI Agent can also render images from learned sources (Beta) for richer, more visual responses. ✅ Transcripts View all chats, see which knowledge sources were used per reply, add missing Q&A entries, and review user context (guest/logged-in status and IP addresses). ✅ Cost-Optimized AI Usage Smart token management minimizes API charges. Intelligent request optimization ensures you pay only for what you need. Configure rate limits to control expenses. ✅ Streaming AI Responses Real-time word-by-word AI replies for faster, more natural conversations. Especially useful when short answers setting is disabled – long responses are printed naturally and quickly instead of making users wait for the full response to be ready. ✅ Customizable Chat Experience Unlimited widgets including Message Starters, Message Prompts, Chat History, Links, Lead Generation, and custom announcements. The Lead Generation widget collects user name and email before allowing conversation to start—so you know who is chatting and can follow up or add them to your leads list. Fully customizable greetings with emoji support. Simplified single-step widget publishing makes adding widgets effortless. ✅ Flexible Vector Storage Choose local WordPress database (free, unlimited) or Pinecone for enterprise-scale knowledge bases.

External Services This plugin connects to third-party AI services to power the AI Chat Agent, AI Copilot, image generation, and video generation features. No data is transmitted until you explicitly configure an API key and initiate a request. What data is sent: Your WordPress content (post text, metadata, product details) as included in AI prompts, and MCP tool execution results when using the MCP server with external AI clients. When data is sent: Only when you have configured an API key for a provider AND actively send a message to the AI agent or Copilot, or when an external MCP client makes an authenticated request to the MCP server endpoint. Supported services and their policies: OpenAI — Used for GPT models (AI Chat Agent, AI Copilot), GPT Image / DALL·E (image generation), and Sora (video generation) Terms of Use | Privacy Policy Anthropic Claude — Used for Claude AI models (AI Chat Agent, AI Copilot) Terms of Service | Privacy Policy Google Gemini — Used for Gemini AI models (AI Chat Agent, AI Copilot), Gemini Image + Imagen 4 (image generation), and Veo 2/3 (video generation) Terms of Service | Privacy Policy Google Search Console – Used only when you connect your Google account in the SEO settings, for read-only site/search performance data. Terms of Service | Privacy Policy When using the MCP server with external AI clients (ChatGPT, Claude Desktop, LibreChat, etc.), API requests are made by the AI client’s backend servers to your WordPress MCP endpoint. The plugin itself does not send data to third parties in this scenario — the external MCP client initiates all communication.
