Yes. RAG Chat uses Claude AI to generate responses. You'll need an API key from console.anthropic.com. Creating an account is free; you only pay for actual usage (typically $1-5/month for small-to-medium sites).
Your content is indexed and stored in your WordPress database. Only small, relevant text chunks are sent to Claude's API when answering a specific question, along with the visitor's question. No third-party vector databases are used.
The Free version gives you a working AI chatbot with up to 200 indexed chunks. Pro unlocks unlimited indexing, WooCommerce support, FAQ page generation from content gaps, analytics, email collection, and the ability to remove branding.
Yes! The Pro plan automatically indexes your products including prices, sale prices, SKUs, stock status, categories, and attributes. Your chatbot becomes a knowledgeable product assistant.
RAG Chat only answers from your indexed content. If the information isn't in your content, it will tell the visitor it doesn't have that information rather than making something up. This is the core advantage of RAG over generic chatbots.
Absolutely. You can change the primary color, position (left or right), title, subtitle, welcome message, avatar image, and even add custom CSS (Pro). The widget uses a modern dark theme that looks great on any site.
When a visitor asks a question that the AI can't answer from your content, that question is logged as a "content gap." This is your content roadmap. With Pro, you can generate FAQ pages from these gaps with one click, then re-index so the chatbot can answer those questions next time.
