MxChat – AI Chatbot & Content Generation for WordPress

MxChat supports 100+ AI models, including OpenAI GPT-6.1 Sol and GPT-6, Anthropic Claude Haiku, Sonnet and Opus 5.5, Google Gemini 3.8 Flash and Gemini 4 Argon, xAI Grok 4.7 and DeepSeek Flash. With OpenRouter integration, you get models from OpenAI, Anthropic, Google, Meta, Mistral, and other providers with a single API key. When a provider discontinues a model, MxChat moves your chatbot to its current replacement automatically and shows you a notice.

For OpenAI, visit platform.openai.com and create an account. For Anthropic Claude, visit console.anthropic.com. For Google Gemini, visit ai.google.dev. For xAI Grok, visit x.ai. For DeepSeek, visit platform.deepseek.com. For OpenRouter (100+ models), visit openrouter.ai. Each provider offers different pricing tiers and free credits for new users.

Yes. MxChat supports unlimited knowledge base training using RAG (Retrieval-Augmented Generation) technology. Import content from WordPress pages, posts, WooCommerce products, custom post types, PDFs, Word documents, text files, sitemaps, and manual Q&A entries. The AI chatbot will use your content to provide accurate, contextually relevant responses.

RAG (Retrieval-Augmented Generation) is an AI technique that retrieves relevant information from your knowledge base before generating responses. When a visitor asks a question, MxChat searches your trained content using vector embeddings, finds the most relevant matches, and provides that context to the AI model. This ensures accurate, factual answers based on your actual website content rather than generic AI responses.

Yes. MxChat includes full WooCommerce integration. The AI chatbot can be trained on your product catalog including titles, descriptions, pricing, SKUs, categories, and custom fields. Enable auto-sync to automatically update the knowledge base when products change. Your chatbot can answer questions about products, pricing, availability, and help customers find what they need.

Yes. The free plugin lets you set the widget position (left or right), the greeting and placeholder text, and add your own custom CSS. The MxChat Theme Customizer add-on (Pro) handles the rest of the look: custom colors for around 20 widget elements, your own chatbot icon and avatar image, chat bubble size, light, dark and system themes, widget layouts, and a built-in CSS editor. Its AI Theme Generator lets you describe the design you want and generates the theme for you.

You can add the chatbot using the shortcode [mxchat_chatbot floating="yes"] for a floating widget or [mxchat_chatbot floating="no"] for an embedded chat. Alternatively, enable “Append to Body” in settings to automatically display the chatbot on all pages without shortcodes.

With the Complianz Integration setting on (Settings, Lead Capture, Privacy and Compliance), the chat appears only after Complianz confirms that the visitor has accepted marketing cookies, and MxChat waits for the Complianz script on the page to give that answer. On a page where Complianz does not load its script, the answer never comes, so the chat stays hidden for every visitor on that page, even one who has already accepted cookies elsewhere on your site. To fix it, make sure the Complianz script loads on that page: check that the page is not excluded in your Complianz settings, and that a caching or optimization plugin is not removing that script or blocking it from running there. Delaying the script is fine, because the chat appears as soon as Complianz runs. If you do not need a consent check for the chat, turn the Complianz Integration setting off. A chat placed in a page (the shortcode with floating set to no, or the MxChat block) waits for the same consent and shows a one-line note in its place until the visitor accepts.

Yes. MxChat supports real-time streaming responses for OpenAI, Anthropic Claude, xAI Grok, and DeepSeek models. Streaming displays AI responses word-by-word as they’re generated, providing a faster, more engaging chat experience for your visitors.

The Chat Transcripts dashboard provides comprehensive conversation management. View all chat histories, see detailed conversation flows, track which knowledge sources the AI used for each response, monitor user engagement, and analyze chat analytics including daily activity, peak hours, and user distribution.

Yes. Give their role the mxchat_view_transcripts capability and they see only Transcripts under the MxChat menu: they can read, search and export chats and leads, but cannot delete anything, translate chats or change settings, and the rest of the MxChat and WordPress settings stay closed to them. Administrators already have the capability. Add it with a role editor plugin, or with two lines of code that run once, for example for a role called support_agent:

$role = get_role( 'support_agent' ); $role->add_cap( 'mxchat_view_transcripts' );

To reuse a capability the role already has instead, return its name from the mxchat_transcripts_capability filter.

Yes. MxChat includes full knowledge source transparency. In the Chat Transcripts and the optional debug panel, you can see exactly which pages, posts, products, or Q&A entries the AI retrieved and used to generate each response, along with relevance scores.

No. MxChat includes free, unlimited local vector storage in your WordPress database. Pinecone integration is optional and recommended only for enterprise-scale knowledge bases with thousands of entries requiring faster search performance.

Yes. The AI chatbot supports multi-language conversations and automatically responds in the language your visitors use. MxChat also supports right-to-left (RTL) languages like Arabic and Hebrew.

API costs depend on your chosen provider and model. OpenAI, Anthropic, Google, and others charge based on token usage. DeepSeek and Google Gemini offer generous free tiers. MxChat includes intelligent token optimization to minimize API costs, and Transcripts show the tokens each reply used, including tokens served from the provider’s prompt cache. You can also set rate limits for guests and logged-in users to control usage.

Yes. All conversation data is stored locally on your WordPress site, giving you complete control. Configure automatic data retention policies, export chat transcripts, or delete conversations as needed for compliance.

Yes. MxChat includes role-based access controls. Restrict the chatbot to logged-in users only, specific user roles, or keep it public. You can also restrict specific knowledge base content to certain user roles.

Yes. MxChat integrates with Slack for live agent handoff. When the AI cannot help or a visitor requests human support, conversations can be seamlessly transferred to your team via Slack.

Actions are capabilities your chatbot can perform — lead capture, appointment booking, support tickets, page redirects, image generation, web search, or custom JavaScript. MxChat gives you two ways to fire them, and you can use either one or both together:

• Trigger Phrases – the original system. A smart vector embedding match fires an action when a visitor’s message matches a phrase you’ve set up. Precise, deterministic control over exactly when each action runs.
• AI Tools (function calling) – the chatbot decides on its own when to run an enabled action, straight from natural language, with no phrases to configure. The easiest way to get started; it needs a tool-capable AI model.

Manage both from the Actions area in your MxChat settings, which holds Trigger Phrases and AI Tools side by side.

Yes. Enable document uploads to let visitors chat with PDFs and Word documents. The AI extracts and processes document content in real-time, allowing contextual Q&A about uploaded files.

Yes. With OpenAI GPT Image and Google Nano Banana integration, the AI chatbot can generate images based on user descriptions directly within the chat conversation.

Enable auto-sync for posts, pages, WooCommerce products, or custom post types. When you publish or update content, MxChat automatically updates the knowledge base with the new information, including pages built with ACF Blocks or page builders such as Breakdance, Oxygen, Bricks and Divi. A save that changes nothing sends no request to your embedding provider. No manual re-importing required.

Yes. MxChat fully supports Advanced Custom Fields. ACF field data, including fields inside ACF Blocks, is automatically included when importing content. Use the ACF Field Settings to control which custom fields are included or excluded from the knowledge base—perfect for hiding private notes or internal data from the chatbot.

Built in: OpenAI (text-embedding-ada-002, text-embedding-3-small, text-embedding-3-large), Google Gemini embedding, and Voyage AI. You can also use any OpenAI-compatible embeddings endpoint — Ollama, LM Studio, vLLM, LocalAI, or Azure OpenAI — by configuring the Custom Provider under Settings, then enabling “Use custom provider for embeddings” and naming your embedding model (for example nomic-embed-text) in the
