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., test_site)
   • 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
