Dynamic website assistant with DeepSeek AI, Pinecone Vectorstore & site-based routing

This workflow contains community nodes that are only compatible with the self-hosted version of n8n. 🚀 Overview This workflow enables a powerful AI-driven virtual assistant that dynamically responds to website queries using webhook input, Pinecone vector search, and OpenAI agents — all smartly routed based on the source website. 🔧 How It Works 1. Webhook Trigger The workflow starts with a Webhook node that receives query parameters: - query: The user's question - userId: Unique user identifier - site: Website identifier (e.g., testsite) - page: Page identifier (e.g., homepage, pricing) 2. Smart Routing A Switch node directs the request to the correct AI agent based on the site value. Each AI agent uses: - OpenAI GPT-4/3.5 model - Pinecone vector store for context-aware answers - SQL-based memory for consistent multi-turn conversation 3. Contextual AI Agent Each agent is customized per website using: - Site-specific Pinecone namespaces - Predefined system prompts to stay in scope - Webhook context including page, site, and userId 4. Final Response The response is sent back to the originating website using the Respond to Webhook node. 🧠 Use Case Ideal for multi-site platforms that want to serve tailored AI chat experiences per domain or page — whether it’s support, content discovery, or interactive agents. ✅ Highlights - 🧠 Vector search using Pinecone for contextual responses - 🔀 Website-aware logic with Switch node routing - 🔐 No hardcoded API keys - 🧩 Modular agents for scalable multi-site support
