WhatsApp AI Assistant with Voice, Image & Web Search (Pinecone RAG)

This n8n workflow builds a genuinely multimodal AI assistant on WhatsApp. It understands text, images, and voice messages - transcribing audio automatically and analyzing photos with vision AI - and can respond back in either text or generated speech. Behind the scenes, an AI Agent has access to a full toolkit: real-time web search via SerpAPI, a calculator, a Pinecone-backed knowledge base for RAG-style answers, and even MCP client tools for extended capabilities. It's a comprehensive foundation for businesses that want a single, capable WhatsApp assistant handling customer questions, research, and calculations in whatever format the user prefers.
