Automate AI-Powered Responses with Google Sheets, OpenAI, and Supabase

This workflow is designed to create a seamless AI-powered conversational assistant. It begins by monitoring Google Sheets for new user messages, ensuring each message is processed only once. The workflow then formats the conversation context by retrieving chat history and preparing it for AI processing. Using OpenAI's GPT-4 model, along with a vector store for knowledge retrieval and web search capabilities via SerpAPI, the AI generates contextual responses. These responses are then stored back in Google Sheets, completing the loop.
