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.
236
237	= What is RAG technology and how does it work? =
238
239	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.
240
241	= Does MxChat work with WooCommerce? =
242
243	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.

244

MxChat offers extensive customization options including custom colors, chatbot icon, AI avatar, chat bubble size, light/dark/system themes, positioning (left/right), custom CSS, greeting messages, placeholder text, and widget layouts. Use the built-in AI Theme Generator to describe your ideal design and let AI create custom styling automatically.
248
249	= How do I add the chatbot to my WordPress site? =
250
251	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.
252
253	= Does MxChat support streaming responses? =
254
255	Yes. MxChat supports real-time streaming responses for OpenAI, Anthropic Claude, and xAI Grok models. Streaming displays AI responses word-by-word as they're generated, providing a faster, more engaging chat experience for your visitors.
256
257	= What is the Chat Transcripts feature? =
258

260
261	= Can I see which content the AI chatbot used to answer questions? =
262
263	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.
264
265	= Is Pinecone vector database required? =
266
267	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.
268
269	= Does MxChat support multiple languages? =
270
271	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.
272
273	= How much do AI API calls cost? =
274
275	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. You can also set rate limits for guests and logged-in users to control usage.
276
277	= Is MxChat GDPR compliant? =
278
279	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.
280
281	= Can I restrict chatbot access to certain users? =

290
291	Actions are custom triggers that execute when user intent is detected. Create actions for lead capture, appointment booking, support tickets, page redirects, or custom JavaScript. The AI automatically recognizes when users want to perform these actions and triggers them contextually.
292
293	= Can visitors upload documents to chat? =

306
307	Yes. MxChat fully supports Advanced Custom Fields. ACF field data 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.
