🤖 AI Website Chat Widget – Self-Hosted RAG Chatbot
Empower your website with a powerful AI Chat Widget trained on your own content.
The AI Website Chat Widget is a production-ready, self-hosted AI assistant designed for businesses and developers who want complete control over their AI infrastructure and data.
Unlike SaaS chatbot platforms, this solution allows you to use your own LLM API keys (OpenAI, Claude, Groq, or Cloudflare) and run everything on your own server.
Powered by a robust RAG (Retrieval Augmented Generation) pipeline, the system automatically chunks, embeds, and retrieves information from your custom knowledge base, enabling the AI to deliver accurate, context-aware answers based strictly on your content.
Perfect for customer support automation, documentation assistants, SaaS onboarding, internal knowledge bots, and AI-powered help desks.
