mayooear/langchain-supabase-website-chatbot

Implements automated web scraping with customizable CSS selectors to extract and embed website content into Supabase's pgvector extension, enabling semantic search via OpenAI embeddings. The chatbot leverages LangChain's retrieval-augmented generation (RAG) pattern to ground responses in your site's actual content, with a Next.js frontend handling real-time chat interactions. Setup requires configuring target URLs and content extraction rules, then running a batch embedding script before deploying the chat interface.
