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.
