Dynamic Multi-Site AI Assistant with Pinecone & Routing

This n8n workflow creates a powerful, scalable AI chatbot for multiple websites. It starts with a Webhook trigger capturing user queries, user IDs, site identifiers, and page context. A Switch node intelligently routes requests to site-specific AI agents based on the 'site' parameter, ensuring responses are hyper-relevant to each domain.

Each agent leverages OpenAI GPT-4/3.5 models integrated with Pinecone vector stores (using site-specific namespaces) for semantic search of relevant content, plus SQL-based memory for maintaining conversation history across multi-turn interactions. Custom system prompts keep responses in scope, incorporating page and site details for precision.

Benefits include no hardcoded API keys for security, modular design for easy scaling to new sites, and vector-powered contextual accuracy that outperforms basic chatbots. Ideal use cases: multi-tenant SaaS platforms, e-commerce support, content sites needing discovery aids, or enterprise knowledge bases requiring domain-specific AI assistance.

Highlights: Community nodes for self-hosted n8n, webhook responses for seamless frontend integration, and enterprise-grade routing for tailored experiences across sites.
